text: On 17 January 1991, Irving told a reporter from "The Jewish Chronicle" that "The Jews are very foolish not to abandon the gas chamber theory while they still have time". Irving went on to say that he believed antisemitism will increase all over the world because "the Jews have exploited people with the gas chamber legend" and that "In ten years, Israel will cease to exist and the Jews will have to return to Europe". In his 1991 revised edition of "Hitler's War", he had removed all references to death camps and the Holocaust. In a speech given in Hamburg in 1991, Irving stated that in two years' time "this myth of mass murders of Jews in the death factories of Auschwitz, Majdanek and Treblinka ... which in fact never took place" will be disproved (Auschwitz, Majdanek, and Treblinka were all well established as being extermination camps). Two days later, Irving repeated the same speech in Halle before a group of neo-Nazis, and praised Rudolf Hess as "that great German martyr, Rudolf Hess". At another 1991 speech, this time in Canada, Irving called the Holocaust a "hoax", and again predicted that by 1993 the "hoax" would have been "exposed". In that speech, Irving declared, "Gradually the word is getting around Germany. Two years from now too, the German historians will accept that we are right. They will accept that for fifty years they have believed a lie". During that speech given in October 1991, Irving expressed his contempt and hatred for Holocaust survivors by proclaiming that:


title: David Irving

text: Ridicule alone isn't enough, you've got to be tasteless about it. You've got to say things like 'More women died on the back seat of Edward Kennedy's car at Chappaquiddick than in the gas chambers at Auschwitz.' Now you think that's tasteless, what about this? I'm forming an association especially dedicated to all these liars, the ones who try and kid people that they were in these concentration camps, it's called the Auschwitz Survivors, Survivors of the Holocaust and Other Liars, 'ASSHOLs'. Can't get more tasteless than that, but you've got to be tasteless because these people deserve our contempt.


title: David Irving

text: In another 1991 speech, this time in Regina, Irving called the Holocaust "a major fraud... There were no gas chambers. They were fakes and frauds".


title: David Irving

text: In November 1992, Irving was to be a featured speaker at a world anti-Zionist congress in Stockholm that was cancelled by the Swedish government. Also scheduled to attend were fellow Holocaust-deniers Robert Faurisson and Fred A. Leuchter, and Louis Farrakhan, together with representatives of the militant Palestinian group Hamas, the Lebanese militant Shiite group Hezbollah, and the right-wing Russian antisemitic group Pamyat. In a 1993 speech, Irving claimed that there had been only 100,000 Jewish deaths at Auschwitz, "but not from gas chambers. They died from epidemics". Irving went on to claim that most of the Jewish deaths during World War II had been caused by Allied bombing. Irving claimed that "The concentration camp inmates arrived in Berlin or Leipzig or in Dresden just in time for the RAF bombers to set fire to those cities. Nobody knows how many Jews died in those air raids".


title: David Irving

text: In a 1994 speech, Irving lamented that his predictions of 1991 had failed to occur, and complained of the persistence of belief in the "rotting corpse" of the "profitable legend" of the Holocaust. In another 1994 speech, Irving claimed that there was no German policy of genocide of Jews, and that only 600,000 Jews died in concentration camps in World War II, all due to either Allied bombing or disease. At the same time, Irving started to appear more frequently at the annual conferences hosted by the IHR. In a 1995 speech, Irving claimed that the Holocaust was a myth invented by a "world-wide Jewish cabal" to serve their own ends. Irving also spoke on other topics at the IHR gatherings. A frequent theme was the claim that Winston Churchill had advance knowledge of the Japanese plans to attack Pearl Harbor, and refused to warn the Americans, in order to bring the United States into World War II. In 1995 he stated that, "We revisionists, say that gas chambers didn't exist and that the 'factories of death' didn't exist." In 1999, Irving said during a television interview, "I'm a gas chamber denier. I'm a denier that they killed hundreds of thousands of people in gas chambers, yes."


title: David Irving

text: At the same time, Irving maintained an ambivalent attitude to Holocaust denial depending on his audience. In a 1993 letter, Irving lashed out against his former friend Zündel, writing that: "In April 1988 I unhesitatingly agreed to aid your defence as a witness in Toronto. "I would not make the same mistake again". As a penalty for having defended you then, and for having continued to aid you since, my life has come under a gradually mounting attack: I find myself the worldwide victim of mass demonstrations, violence, vituperation and persecution" (emphasis in the original). Irving went on to claim his life had been wonderful until Zündel had got him involved in the Holocaust denial movement: van Pelt argues that Irving was just trying to shift responsibility for his actions in his letter. In an interview with Australian radio in July 1995, Irving claimed that at least four million Jews died in World War II, though he argued that this was due to terrible sanitary conditions inside the concentration camps as opposed to a deliberate policy of genocide in the death camps. Irving's statement led to a very public spat with his former ally Faurisson, who insisted that no Jews were killed in the Holocaust. In 1995, Irving stated in another speech that "I have to take off my hat to my adversaries and the strategies they have employed—the marketing of the very word Holocaust: I half expected to see a little TM after it". Likewise, depending on his audience, during the 1990s Irving either used the absence of a written "Führerbefehl" (Führer order) for the "Final Solution" to argue that Hitler was unaware of the Holocaust, or claimed that the absence of a written order meant there was no Holocaust at all.


title: David Irving

text: Although Irving denies being a racist, he has expressed racist and antisemitic sentiments, both publicly and privately. Irving has often expressed his belief in the conspiracy theory of Jews secretly ruling the world, and that the belief in the reality of the Holocaust was manufactured as part of the same alleged conspiracy. Irving used the label "traditional enemies of the truth" to describe Jews, and in a 1963 article about a speech by Sir Oswald Mosley wrote that the "Yellow Star did not make a showing". In 1992, Irving stated that "the Jews are very foolish not to abandon the gas chamber theory while they still have time" and claimed he "foresees a new wave of antisemitism" the world over due to Jewish "exploitation of the Holocaust myth". During an interview with the American writer Ron Rosenbaum, Irving restated his belief that Jews were his "traditional enemy". In one interview cited in the libel lawsuit, Irving also stated that he would be "willing to put [his] signature" to the "fact" that "a great deal of control over the world is exercised by Jews".


title: David Irving

text: After Irving was sacked by "The Sunday Times" to help them with their serialisation of the Goebbels diaries, he described a group of protesters outside of his apartment as, "All the scum of humanity stand outside. The homosexuals, the gypsies, the lesbians, the Jews, the criminals, the Communists..."


title: David Irving

text: Several of these statements were cited by the judge's decision in Irving's lawsuit against Penguin Books and Deborah Lipstadt, leading the judge to conclude that Irving "had on many occasions spoken in terms which are plainly racist." One example brought was his diary entry for 17 September 1994, in which Irving wrote about a ditty he composed for his young daughter "when half-breed children are wheeled past":


title: David Irving

text: Christopher Hitchens wrote that Irving sang the rhyme to Hitchens's wife, Carol Blue, and daughter, Antonia, in the elevator following drinks in the family's Washington apartment.


title: David Irving

text: After Irving denied the Holocaust in two speeches given in Austria in 1989, the Austrian government issued an arrest warrant for him and barred him from entering the country. In early 1992, a German court found him guilty of Holocaust denial under the "Auschwitzlüge" section of the law against "Volksverhetzung" (a failed appeal by Irving would see the fine rise from 10,000 DM to 30,000 DM), and he was subsequently barred from entering Germany. Other governments followed suit, including Italy and Canada, where he was arrested in November 1992 and deported to the United Kingdom. In an administrative hearing surrounding those events, he was found by the hearing office to have engaged in a "total fabrication" in telling a story of an exit from and return to Canada which would, for technical reasons, have made the original deportation order invalid. He was also barred from entering Australia in 1992, a ban he made five unsuccessful attempts to overturn.


title: David Irving

text: In 1992, Irving signed a contract with Macmillan Publishers for his biography of Joseph Goebbels titled "Goebbels: Mastermind of the Third Reich". Following charges that Irving had selectively "edited" a recently discovered complete edition of Goebbels's diaries in Moscow, Macmillan cancelled the book deal. The decision by "The Sunday Times" (who had bought the rights to serialised extracts from the diaries before Macmillan published them) in July 1992 to hire Irving as a translator of Goebbels's diary was criticised by Austrian-British historian Peter G. J. Pulzer, who argued that Irving, because of his views about the Third Reich, was not the best man for the job. Andrew Neil, the editor of "The Sunday Times", called Irving "reprehensible", but defended hiring him because he was only a "transcribing technician", which others criticised as a poor description of translation work.


title: David Irving

text: On 27 April 1993, Irving was ordered to attend court to be examined on charges relating to the "Loi Gayssot" in France, making it an offence to question the existence or size of the category of crimes against humanity. The law does not extend to extradition, and Irving refused to travel to France. Then, in February 1994, Irving spent 10 days of a three-month sentence in London's Pentonville prison for contempt of court following a legal wrangling over publishing rights.


title: David Irving

text: In 1995, St. Martin's Press of New York City agreed to publish the Goebbels biography: but after protests, they cancelled the contract, leaving Irving in a situation in which, according to D. D. Guttenplan, he was desperate for financial help, publicity, and the need to re-establish his reputation as a historian. The book was eventually self-published.


title: David Irving

text: On 5 September 1996, Irving filed a libel suit against Deborah Lipstadt and her British publisher Penguin Books for publishing the British edition of Lipstadt's book, "Denying the Holocaust", which had first been published in the United States in 1993. In the book, Lipstadt called Irving a Holocaust denier, falsifier and bigot, and said that he manipulated and distorted real documents.


title: David Irving

text: During the trial, Irving claimed that Hitler had not ordered the extermination of the Jews of Europe, was ignorant of the Holocaust and was a friend of the Jews.


title: David Irving

text: Lipstadt hired the British solicitor Anthony Julius to present her case, while Penguin Books hired Kevin Bays and Mark Bateman, libel specialist from media firm Davenport Lyons. They briefed the libel barrister Richard Rampton QC and Penguin also briefed junior barrister Heather Rogers. The defendants (with Penguin's insurers paying the fee) also retained Professor Richard J. Evans, historian and Professor of Modern History at Cambridge University, as an expert witness. Also working as expert witnesses were the American Holocaust historian Christopher Browning, the German historian Peter Longerich, and the Dutch architectural expert Robert Jan van Pelt. The last wrote a report attesting to the fact that the death camps were designed, built and used for the purpose of mass murder, while Browning testified for the reality of the Holocaust. Evans' report was the most comprehensive, in-depth examination of Irving's work:


title: David Irving

text: Not only did Irving lose the case, but in light of the evidence presented at the trial a number of his works that had previously escaped serious scrutiny were brought to public attention. He was also ordered to pay all of Penguin's trial costs, estimated to be as much as £2 million (US$3.2 million), though it is uncertain how much of these costs he would ultimately pay. When he did not meet these, Davenport Lyons moved to make him bankrupt on behalf of their client. He was declared bankrupt in 2002, and lost his home, though he has been able to travel around the world despite his financial problems.


title: David Irving

text: Irving subsequently appealed to the Civil Division of the Court of Appeal. On 20 July 2001, his application for appeal was denied by Lords Justices Pill, Mantell and Buxton.


title: David Irving

text: Early in September 2004, Michael Cullen, the Deputy Prime Minister of New Zealand, announced that Irving would not be permitted to visit the country, where he had been invited by the National Press Club to give a series of lectures under the heading "The Problems of Writing about World War II in a Free Society". The National Press Club defended its invitation of Irving, saying that it amounted not to an endorsement of his views, but rather an opportunity to question him. A government spokeswoman said that "people who have been deported from another country are refused entry" to New Zealand. Irving rejected the ban and attempted to board a Qantas flight for New Zealand from Los Angeles on 17 September 2004. He was not allowed on board.


title: David Irving

text: On 11 November 2005, the Austrian police in the southern state of Styria, acting under the 1989 warrant, arrested Irving. Irving pleaded guilty to the charge of "trivialising, grossly playing down and denying the Holocaust". Irving stated in his plea that he had changed his opinions on the Holocaust, "I said that then based on my knowledge at the time, but by 1991 when I came across the Eichmann papers, I wasn't saying that anymore and I wouldn't say that now. The Nazis did murder millions of Jews." Irving had obtained the papers from Hugo Byttebier, a Belgian who had served in the SS during the war and had escaped to Argentina. Irving was sentenced to three years' imprisonment in accordance with the law prohibiting Nazi activities (, "Prohibition Law"). Irving sat motionless as judge Peter Liebetreu asked him if he had understood the sentence, to which he replied "I'm not sure I do" before being escorted out of the court by Austrian police. Later, Irving said that he was shocked by the severity of the sentence. He had reportedly already purchased a plane ticket home to London.


title: David Irving

text: In December 2006, Irving was released from prison and banned from ever returning to Austria. Upon Irving's arrival in the UK he reaffirmed his position, stating that he felt "no need any longer to show remorse" for his Holocaust views. On 18 May 2007, he was expelled from the 52nd Warsaw International Book Fair in Poland because the books he took there were deemed by the organizers as promoting Nazism and antisemitism, which is in violation of Polish law.


title: David Irving

text: Since then, Irving has continued to work as a freelance writer, despite his troubled public image. He was drawn into the controversy surrounding Bishop Richard Williamson, who in a televised interview recorded in Germany in November 2008 denied the Holocaust took place, only to see Williamson convicted for incitement in April 2010 after refusing to pay a fine of €12,000. Irving subsequently found himself beset by protesters on a book tour of the United States. He has also given lectures and tours in the UK and Europe; one tour to Poland in September 2010 which led to particular criticism included the Treblinka death camp as an itinerary stop. During his 2008 tour of the US, Deborah Lipstadt said Irving's audience was mainly limited to like-minded people.


title: David Irving

text: Irving and Nick Griffin (then the British National Party leader) were invited to speak at a forum on free speech at the Oxford Union on 26 November 2007, along with Anne Atkins and Evan Harris. The debate took place after Oxford Union members voted in favour of it, but was disrupted by protesters. Irving was lecturing to small audiences at venues disclosed to carefully vetted ticket-holders a day or two before the event on topics, including antisemitic conspiracy theories, and at one such event, claiming to write the truth unlike "conformist" historians while asserting fabrications about leading Nazis, the life and death of Heinrich Himmler and the saturation bombings during World War II.


title: David Irving

text: Irving established a website selling Nazi memorabilia in 2009. The items are offered by other people, with Irving receiving a commission from each sale for authenticating them. Irving stated in 2009 that the website was the only way he could make money after being bankrupted in 2002. Items sold through the website include Hitler's walking stick and a lock of the dictator's hair. Irving has also investigated the authenticity of bones purported to be from Hitler and Eva Braun.


title: David Irving

text: In 2009, during an interview with Johann Hari, Irving claimed that Hitler appointed him to be his biographer:


title: David Irving

text: During the same interview, Irving claimed that various Nazis hid what was happening to the Jews from Hitler because he was "the best friend the Jews had in the Third Reich".


title: David Irving

text: In October 2008, controversy arose in Norway over Irving's invitation to speak at the 2009 Norwegian Festival of Literature. Several of Norway's most distinguished authors protested against the invitation. The leader of the board for the festival, Jesper Holte, defended the invitation by stating: "Our agenda is to invite a liar and a falsifier of history to a festival about truth. And confront him with this. Irving has been invited to discuss his concept of truth in light of his activity as a writer of historical books and the many accusations he has been exposed to as a consequence of this." Although Irving was introduced in the festival's webpages as "historian and writer", the board chair leader defended the more aggressive language being used to characterise Irving in connection with the controversy that had arisen. Lars Saabye Christensen and Roy Jacobsen were two authors who had threatened to boycott the festival on account of Irving's invitation, and Anne B. Ragde stated that Sigrid Undset would have turned in her grave. As the festival has as its subsidiary name "Sigrid Undset Days", a representative of Undset's family had requested that the name of the Nobel laureate be removed in connection with the festival. Also, the Norwegian free speech organization Fritt Ord was critical of letting Irving speak at the festival and had requested that its logo be removed. In addition, Edvard Hoem announced that he would not attend the 2009 festival with Irving taking part. Per Edgar Kokkvold, leader of the Norwegian Press Confederation, advocated cancelling Irving's invitation.


title: David Irving

text: Days after the controversy had started, the invitation was rescinded. This led to the resignation of Stig Sæterbakken from his position as content director as he was the person who had invited Irving to the event. The head of the Norwegian Festival of Literature, Randi Skeie, deplored what had taken place: "Everything is fine as long as everyone agrees, but things get more difficult when one doesn't like the views being put forward." Sæterbakken called his colleagues "damned cowards", arguing that they were walking in lockstep.


title: David Irving

text: According to editor-in-chief Sven Egil Omdal of "Stavanger Aftenblad", the opposition to Irving's participation at the festival appeared as a concerted effort. He suggested that campaign journalism from two of Norway's largest newspapers, "Dagbladet" and "Aftenposten", and Norway's public service broadcaster NRK was behind the controversy.


title: David Irving

text: David Irving commented that he had not been told that the festival was going to present him as a liar, and that he was preparing a lecture about the real history of what took place in Norway during World War II, contrary to what official historians have presented. Irving stated that he had thought the Norwegian people to be made of tougher stuff.


title: David Irving

text: Only days after the cancellation Irving announced that he would go to Lillehammer during the literature festival and deliver his two-hour lecture from a hotel room.


title: David Irving

text: Irving, once held in regard for his expert knowledge of German military archives, was a controversial figure from the start. His interpretations of the war were widely regarded as unduly favourable to the German side. At first this was seen as personal opinion, unpopular but consistent with full respectability as a historian.


title: David Irving

text: By 1988, however, Irving had begun to reject the status of the Holocaust as a systematic and deliberate genocide. He soon became the main proponent of Holocaust denial. This, along with his association with far-right circles, dented his standing as a historian. A marked change in Irving's reputation can be seen in the surveys of the historiography of the Third Reich produced by Ian Kershaw. In the first edition of Kershaw's book "The Nazi Dictatorship" in 1985, Irving was called a "maverick" historian working outside the mainstream of the historical profession. By the time of the fourth edition of "The Nazi Dictatorship" in 2000, Irving was described only as a historical writer who had in the 1970s engaged in "provocations" intended to provide an "exculpation of Hitler's role in the Final Solution". Other critical responses to his work tend to follow this pattern.


title: David Irving

text: The description of Irving as a historian, rather than a historical author, is controversial, with some publications since the libel trial continuing to refer to him as a "historian" or "disgraced historian", while others insist he is not a historian, and have adopted alternatives such as "author"


title: David Irving

text: The military historian John Keegan praised Irving for his "extraordinary ability to describe and analyse Hitler's conduct of military operations, which was his main occupation during the Second World War". Donald Cameron Watt, Emeritus Professor of Modern History at the London School of Economics, wrote that he admires some of Irving's work as a historian, though he rejects his conclusions about the Holocaust. At the libel proceedings against Irving, Watt declined Irving's request to testify, appearing only after a subpoena was ordered. He testified that Irving had written a "very, very effective piece of historical scholarship" in the 1960s, which was unrelated to his controversial work. He also said that Irving was "not in the top class" of military historians.


title: David Irving

text: In 1961, while living in Spain, Irving met and married a Spaniard, María del Pilar Stuyck. They have four children. They divorced in 1981. In 1992, Irving began a relationship with a Danish model, Bente Hogh. They have a daughter, born in 1994.


title: David Irving

text: Irving's daughter Josephine suffered from schizophrenia. She was involved in a car crash in 1996 which resulted in her having to have both of her legs amputated. In September 1999, at the age of 32, she committed suicide by throwing herself out of a window of her central London flat. One of the wreaths sent to her funeral contained a card which stated, "Truly a merciful death, Philipp Bouhler and friends". The reference to Bouhler was a reference to the Nazi who was in charge of Hitler's euthanasia programme. Irving described it as a "very cruel taunt".


title: Chromatography

text: In chemical analysis, chromatography is a laboratory technique for the separation of a mixture into its components. The mixture is dissolved in a fluid solvent (gas or liquid) called the "mobile phase", which carries it through a system (a column, a capillary tube, a plate, or a sheet) on which a material called the "stationary phase" is fixed. Because the different constituents of the mixture tend to have different affinities for the stationary phase and are retained for different lengths of time depending on their interactions with its surface sites, the constituents travel at different apparent velocities in the mobile fluid, causing them to separate. The separation is based on the differential partitioning between the mobile and the stationary phases. Subtle differences in a compound's partition coefficient result in differential retention on the stationary phase and thus affect the separation.


title: Chromatography

text: Chromatography may be preparative or analytical. The purpose of preparative chromatography is to separate the components of a mixture for later use, and is thus a form of purification. This process is associated with higher costs due to its mode of production. Analytical chromatography is done normally with smaller amounts of material and is for establishing the presence or measuring the relative proportions of analytes in a mixture. The two types are not mutually exclusive.


title: Chromatography

text: Chromatography, pronounced , is derived from Greek χρῶμα "chroma", which means "color", and γράφειν "graphein", which means "to write". The combination of these two terms was directly inherited from the invention of the technique first used to separate pigments.


title: Chromatography

text: Chromatography was first devised in Russia by the Italian-born scientist Mikhail Tsvet in 1900. He developed the technique and coined the term "chromatography" in the first decade of the 20th century, primarily for the separation of plant pigments such as chlorophyll, carotenes, and xanthophylls. Since these components separate in bands of different colors (green, orange, and yellow, respectively) they directly inspired the name of the technique. New types of chromatography developed during the 1930s and 1940s made the technique useful for many separation processes.


title: Chromatography

text: Chromatography technique developed substantially as a result of the work of Archer John Porter Martin and Richard Laurence Millington Synge during the 1940s and 1950s, for which they won the 1952 Nobel Prize in Chemistry. They established the principles and basic techniques of partition chromatography, and their work encouraged the rapid development of several chromatographic methods: paper chromatography, gas chromatography, and what would become known as high-performance liquid chromatography. Since then, the technology has advanced rapidly. Researchers found that the main principles of Tsvet's chromatography could be applied in many different ways, resulting in the different varieties of chromatography described below. Advances are continually improving the technical performance of chromatography, allowing the separation of increasingly similar molecules.


title: Chromatography

text: Chromatography is based on the concept of partition coefficient. Any solute partitions between two immiscible solvents. When we make one solvent immobile (by adsorption on a solid support matrix) and another mobile it results in most common applications of chromatography. If the matrix support, or stationary phase, is polar (e.g. paper, silica etc.) it is forward phase chromatography, and if it is non-polar (C-18) it is reverse phase.


title: Chromatography

text: Column chromatography is a separation technique in which the stationary bed is within a tube. The particles of the solid stationary phase or the support coated with a liquid stationary phase may fill the whole inside volume of the tube (packed column) or be concentrated on or along the inside tube wall leaving an open, unrestricted path for the mobile phase in the middle part of the tube (open tubular column). Differences in rates of movement through the medium are calculated to different retention times of the sample.


title: Chromatography

text: In 1978, W. Clark Still introduced a modified version of column chromatography called "flash column chromatography" (flash). The technique is very similar to the traditional column chromatography, except that the solvent is driven through the column by applying positive pressure. This allowed most separations to be performed in less than 20 minutes, with improved separations compared to the old method. Modern flash chromatography systems are sold as pre-packed plastic cartridges, and the solvent is pumped through the cartridge. Systems may also be linked with detectors and fraction collectors providing automation. The introduction of gradient pumps resulted in quicker separations and less solvent usage.


title: Chromatography

text: In expanded bed adsorption, a fluidized bed is used, rather than a solid phase made by a packed bed. This allows omission of initial clearing steps such as centrifugation and filtration, for culture broths or slurries of broken cells.


title: Chromatography

text: Phosphocellulose chromatography utilizes the binding affinity of many DNA-binding proteins for phosphocellulose. The stronger a protein's interaction with DNA, the higher the salt concentration needed to elute that protein.


title: Chromatography

text: "Planar chromatography" is a separation technique in which the stationary phase is present as or on a plane. The plane can be a paper, serving as such or impregnated by a substance as the stationary bed (paper chromatography) or a layer of solid particles spread on a support such as a glass plate (thin-layer chromatography). Different compounds in the sample mixture travel different distances according to how strongly they interact with the stationary phase as compared to the mobile phase. The specific Retention factor (R) of each chemical can be used to aid in the identification of an unknown substance.


title: Chromatography

text: Paper chromatography is a technique that involves placing a small dot or line of sample solution onto a strip of "chromatography paper". The paper is placed in a container with a shallow layer of solvent and sealed. As the solvent rises through the paper, it meets the sample mixture, which starts to travel up the paper with the solvent. This paper is made of cellulose, a polar substance, and the compounds within the mixture travel further if they are less polar. More polar substances bond with the cellulose paper more quickly, and therefore do not travel as far.


title: Chromatography

text: Thin-layer chromatography (TLC) is a widely employed laboratory technique used to separate different biochemicals on the basis of their relative attractions to the stationary and mobile phases. It is similar to paper chromatography. However, instead of using a stationary phase of paper, it involves a stationary phase of a thin layer of adsorbent like silica gel, alumina, or cellulose on a flat, inert substrate. TLC is very versatile; multiple samples can be separated simultaneously on the same layer, making it very useful for screening applications such as testing drug levels and water purity. Possibility of cross-contamination is low since each separation is performed on a new layer. Compared to paper, it has the advantage of faster runs, better separations, better quantitative analysis, and the choice between different adsorbents. For even better resolution and faster separation that utilizes less solvent, high-performance TLC can be used. An older popular use had been to differentiate chromosomes by observing distance in gel (separation of was a separate step).


title: Chromatography

text: A molecule with a high affinity for the chromatography matrix (the displacer) competes effectively for binding sites, and thus displaces all molecules with lesser affinities.


title: Chromatography

text: There are distinct differences between displacement and elution chromatography. In elution mode, substances typically emerge from a column in narrow, Gaussian peaks. Wide separation of peaks, preferably to baseline, is desired for maximum purification. The speed at which any component of a mixture travels down the column in elution mode depends on many factors. But for two substances to travel at different speeds, and thereby be resolved, there must be substantial differences in some interaction between the biomolecules and the chromatography matrix. Operating parameters are adjusted to maximize the effect of this difference. In many cases, baseline separation of the peaks can be achieved only with gradient elution and low column loadings. Thus, two drawbacks to elution mode chromatography, especially at the preparative scale, are operational complexity, due to gradient solvent pumping, and low throughput, due to low column loadings. Displacement chromatography has advantages over elution chromatography in that components are resolved into consecutive zones of pure substances rather than "peaks". Because the process takes advantage of the nonlinearity of the isotherms, a larger column feed can be separated on a given column with the purified components recovered at significantly higher concentrations.


title: Chromatography

text: Gas chromatography (GC), also sometimes known as gas-liquid chromatography, (GLC), is a separation technique in which the mobile phase is a gas. Gas chromatographic separation is always carried out in a column, which is typically "packed" or "capillary". Packed columns are the routine work horses of gas chromatography, being cheaper and easier to use and often giving adequate performance. Capillary columns generally give far superior resolution and although more expensive are becoming widely used, especially for complex mixtures. Further, capillary columns can be split into three classes: porous layer open tubular (PLOT), wall-coated open tubular (WCOT) and support-coated open tubular (SCOT) columns. PLOT columns are unique in a way that the stationary phase is adsorbed to the column walls, while WCOT columns have a stationary phase that is chemically bonded to the walls. SCOT columns are in a way the combination of the two types mentioned in a way that they have support particles adhered to column walls, but those particles have liquid phase chemically bonded onto them. Both types of column are made from non-adsorbent and chemically inert materials. Stainless steel and glass are the usual materials for packed columns and quartz or fused silica for capillary columns.


title: Chromatography

text: Gas chromatography is based on a partition equilibrium of analyte between a solid or viscous liquid stationary phase (often a liquid silicone-based material) and a mobile gas (most often helium). The stationary phase is adhered to the inside of a small-diameter (commonly 0.53 – 0.18mm inside diameter) glass or fused-silica tube (a capillary column) or a solid matrix inside a larger metal tube (a packed column). It is widely used in analytical chemistry; though the high temperatures used in GC make it unsuitable for high molecular weight biopolymers or proteins (heat denatures them), frequently encountered in biochemistry, it is well suited for use in the petrochemical, environmental monitoring and remediation, and industrial chemical fields. It is also used extensively in chemistry research.


title: Chromatography

text: Liquid chromatography (LC) is a separation technique in which the mobile phase is a liquid. It can be carried out either in a column or a plane. Present day liquid chromatography that generally utilizes very small packing particles and a relatively high pressure is referred to as high-performance liquid chromatography (HPLC).


title: Chromatography

text: In HPLC the sample is forced by a liquid at high pressure (the mobile phase) through a column that is packed with a stationary phase composed of irregularly or spherically shaped particles, a porous monolithic layer, or a porous membrane. Monoliths are "sponge-like chromatographic media" and are made up of an unending block of organic or inorganic parts. HPLC is historically divided into two different sub-classes based on the polarity of the mobile and stationary phases. Methods in which the stationary phase is more polar than the mobile phase (e.g., toluene as the mobile phase, silica as the stationary phase) are termed normal phase liquid chromatography (NPLC) and the opposite (e.g., water-methanol mixture as the mobile phase and C18 (octadecylsilyl) as the stationary phase) is termed reversed phase liquid chromatography (RPLC).

text: Affinity chromatography is based on selective non-covalent interaction between an analyte and specific molecules. It is very specific, but not very robust. It is often used in biochemistry in the purification of proteins bound to tags. These fusion proteins are labeled with compounds such as His-tags, biotin or antigens, which bind to the stationary phase specifically. After purification, these tags are usually removed and the pure protein is obtained.


title: Chromatography

text: Affinity chromatography often utilizes a biomolecule's affinity for a metal (Zn, Cu, Fe, etc.). Columns are often manually prepared. Traditional affinity columns are used as a preparative step to flush out unwanted biomolecules.


title: Chromatography

text: However, liquid chromatography techniques exist that do utilize affinity chromatography properties. Immobilized metal affinity chromatography (IMAC) is useful to separate the aforementioned molecules based on the relative affinity for the metal. Often these columns can be loaded with different metals to create a column with a targeted affinity.

text: Supercritical fluid chromatography is a separation technique in which the mobile phase is a fluid above and relatively close to its critical temperature and pressure.


title: Chromatography

text: Ion exchange chromatography (usually referred to as ion chromatography) uses an ion exchange mechanism to separate analytes based on their respective charges. It is usually performed in columns but can also be useful in planar mode. Ion exchange chromatography uses a charged stationary phase to separate charged compounds including anions, cations, amino acids, peptides, and proteins. In conventional methods the stationary phase is an ion-exchange resin that carries charged functional groups that interact with oppositely charged groups of the compound to retain. There are two types of ion exchange chromatography: Cation-Exchange and Anion-Exchange. In the Cation-Exchange Chromatography the stationary phase has negative charge and the exchangeable ion is a cation, whereas, in the Anion-Exchange Chromatography the stationary phase has positive charge and the exchangeable ion is an anion. Ion exchange chromatography is commonly used to purify proteins using FPLC.


title: Chromatography

text: Size-exclusion chromatography (SEC) is also known as "gel permeation chromatography" (GPC) or "gel filtration chromatography" and separates molecules according to their size (or more accurately according to their hydrodynamic diameter or hydrodynamic volume).


title: Chromatography

text: Smaller molecules are able to enter the pores of the media and, therefore, molecules are trapped and removed from the flow of the mobile phase. The average residence time in the pores depends upon the effective size of the analyte molecules. However, molecules that are larger than the average pore size of the packing are excluded and thus suffer essentially no retention; such species are the first to be eluted. It is generally a low-resolution chromatography technique and thus it is often reserved for the final, "polishing" step of a purification. It is also useful for determining the tertiary structure and quaternary structure of purified proteins, especially since it can be carried out under native solution conditions.


title: Chromatography

text: An expanded bed chromatographic adsorption (EBA) column for a biochemical separation process comprises a pressure equalization liquid distributor having a self-cleaning function below a porous blocking sieve plate at the bottom of the expanded bed, an upper part nozzle assembly having a backflush cleaning function at the top of the expanded bed, a better distribution of the feedstock liquor added into the expanded bed ensuring that the fluid passed through the expanded bed layer displays a state of piston flow. The expanded bed layer displays a state of piston flow. The expanded bed chromatographic separation column has advantages of increasing the separation efficiency of the expanded bed.


title: Chromatography

text: Expanded-bed adsorption (EBA) chromatography is a convenient and effective technique for the capture of proteins directly from unclarified crude sample. In EBA chromatography, the settled bed is first expanded by upward flow of equilibration buffer. The crude feed, a mixture of soluble proteins, contaminants, cells, and cell debris, is then passed upward through the expanded bed. Target proteins are captured on the adsorbent, while particulates and contaminants pass through. A change to elution buffer while maintaining upward flow results in desorption of the target protein in expanded-bed mode. Alternatively, if the flow is reversed, the adsorbed particles will quickly settle and the proteins can be desorbed by an elution buffer. The mode used for elution (expanded-bed versus settled-bed) depends on the characteristics of the feed. After elution, the adsorbent is cleaned with a predefined cleaning-in-place (CIP) solution, with cleaning followed by either column regeneration (for further use) or storage.


title: Chromatography

text: Reversed-phase chromatography (RPC) is any liquid chromatography procedure in which the mobile phase is significantly more polar than the stationary phase. It is so named because in normal-phase liquid chromatography, the mobile phase is significantly less polar than the stationary phase. Hydrophobic molecules in the mobile phase tend to adsorb to the relatively hydrophobic stationary phase. Hydrophilic molecules in the mobile phase will tend to elute first. Separating columns typically comprise a C8 or C18 carbon-chain bonded to a silica particle substrate.


title: Chromatography

text: Hydrophobic Interaction Chromatography (HIC) is a purification and analytical technique that separates analytes, such as proteins, based on hydrophobic interactions between that analyte and the chromatographic matrix. It can provide a non-denaturing orthogonal approach to reversed phase separation, preserving native structures and potentially protein activity. In hydrophobic interaction chromatography, the matrix material is lightly substituted with hydrophobic groups. These groups can range from methyl, ethyl, propyl, butyl, octyl, or phenyl groups. At high salt concentrations, non-polar sidechains on the surface on proteins "interact" with the hydrophobic groups; that is, both types of groups are excluded by the polar solvent (hydrophobic effects are augmented by increased ionic strength). Thus, the sample is applied to the column in a buffer which is highly polar, which drives an association of hydrophobic patches on the analyte with the stationary phase. The eluent is typically an aqueous buffer with decreasing salt concentrations, increasing concentrations of detergent (which disrupts hydrophobic interactions), or changes in pH. Of critical importance is the type of salt used, with more kosmotropic salts as defined by the Hofmeister series providing the most water structuring around the molecule and resulting hydrophobic pressure. Ammonium sulfate is frequently used for this purpose. The addition of organic solvents or other less polar constituents may assist in improving resolution.


title: Chromatography

text: In general, Hydrophobic Interaction Chromatography (HIC) is advantageous if the sample is sensitive to pH change or harsh solvents typically used in other types of chromatography but not high salt concentrations. Commonly, it is the amount of salt in the buffer which is varied. In 2012, Müller and Franzreb described the effects of temperature on HIC using Bovine Serum Albumin (BSA) with four different types of hydrophobic resin. The study altered temperature as to effect the binding affinity of BSA onto the matrix. It was concluded that cycling temperature from 50 to 10 degrees would not be adequate to effectively wash all BSA from the matrix but could be very effective if the column would only be used a few times. Using temperature to effect change allows labs to cut costs on buying salt and saves money.


title: Chromatography

text: If high salt concentrations along with temperature fluctuations want to be avoided you can use a more hydrophobic to compete with your sample to elute it. [source] This so-called salt independent method of HIC showed a direct isolation of Human Immunoglobulin G (IgG) from serum with satisfactory yield and used Beta-cyclodextrin as a competitor to displace IgG from the matrix. This largely opens up the possibility of using HIC with samples which are salt sensitive as we know high salt concentrations precipitate proteins.


title: Chromatography

text: Hydrodynamic chromatography (HDC) is derived from the observed phenomenon that large droplets move faster than small ones. In a column, this happens because the center of mass of larger droplets is prevented from being as close to the sides of the column as smaller droplets because of their larger overall size. Larger droplets will elute first from the middle of the column while smaller droplets stick to the sides of the column and elute last. This form of chromatography is useful for separating analytes by molar mass, size, shape, and structure when used in conjunction with light scattering detectors, viscometers, and refractometers. The two main types of HDC are open tube and packed column. Open tube offers rapid separation times for small particles, whereas packed column HDC can increase resolution and is better suited for particles with an average molecular mass larger than formula_1 daltons. HDC differs from other types of chromatography because the separation only takes place in the interstitial volume, which is the volume surrounding and in between particles in a packed column.


title: Chromatography

text: HDC shares the same order of elution as Size Exclusion Chromatography (SEC) but the two processes still vary in many ways. In a study comparing the two types of separation, Isenberg, Brewer, Côté, and Striegel use both methods for polysaccharide characterization and conclude that HDC coupled with multiangle light scattering (MALS) achieves more accurate molar mass distribution when compared to off-line MALS than SEC in significantly less time. This is largely due to SEC being a more destructive technique because of the pores in the column degrading the analyte during separation, which tends to impact the mass distribution. However, the main disadvantage of HDC is low resolution of analyte peaks, which makes SEC a more viable option when used with chemicals that are not easily degradable and where rapid elution is not important.


title: Chromatography

text: HDC plays an especially important role in the field of microfluidics. The first successful apparatus for HDC-on-a-chip system was proposed by Chmela, et al. in 2002. Their design was able to achieve separations using an 80 mm long channel on the timescale of 3 minutes for particles with diameters ranging from 26 to 110 nm, but the authors expressed a need to improve the retention and dispersion parameters. In a 2010 publication by Jellema, Markesteijn, Westerweel, and Verpoorte, implementing HDC with a recirculating bidirectional flow resulted in high resolution, size based separation with only a 3 mm long channel. Having such a short channel and high resolution was viewed as especially impressive considering that previous studies used channels that were 80 mm in length. For a biological application, in 2007, Huh, et al. proposed a microfluidic sorting device based on HDC and gravity, which was useful for preventing potentially dangerous particles with diameter larger than 6 microns from entering the bloodstream when injecting contrast agents in ultrasounds. This study also made advances for environmental sustainability in microfluidics due to the lack of outside electronics driving the flow, which came as an advantage of using a gravity based device.


title: Chromatography

text: In some cases, the selectivity provided by the use of one column can be insufficient to provide resolution of analytes in complex samples. Two-dimensional chromatography aims to increase the resolution of these peaks by using a second column with different physico-chemical (chemical classification) properties. Since the mechanism of retention on this new solid support is different from the first dimensional separation, it can be possible to separate compounds by two-dimensional chromatography that are indistinguishable by one-dimensional chromatography. Furthermore, the separation on the second dimension occurs faster than the first dimension. An example of a two-dimensional TLC separation is where the sample is spotted at one corner of a square plate, developed, air-dried, then rotated by 90° and usually redeveloped in a second solvent system. Two-dimensional chromatography can be applied to GC or LC separations. This separation method can also be used in a heart-cutting approach, where specific regions of interest on the first dimension are selected for separation by the second dimension, or in a comprehensive approach, where all the analytes from the first dimension undergo the second dimension separation.


title: Chromatography

text: The simulated moving bed (SMB) technique is a variant of high performance liquid chromatography; it is used to separate particles and/or chemical compounds that would be difficult or impossible to resolve otherwise. This increased separation is brought about by a valve-and-column arrangement that is used to lengthen the stationary phase indefinitely.


title: Chromatography

text: In the moving bed technique of preparative chromatography the feed entry and the analyte recovery are simultaneous and continuous, but because of practical difficulties with a continuously moving bed, simulated moving bed technique was proposed. In the simulated moving bed technique instead of moving the bed, the sample inlet and the analyte exit positions are moved continuously, giving the impression of a moving bed.


title: Chromatography

text: True moving bed chromatography (TMBC) is only a theoretical concept. Its simulation, SMBC is achieved by the use of a multiplicity of columns in series and a complex valve arrangement, which provides for sample and solvent feed, and also analyte and waste takeoff at appropriate locations of any column, whereby it allows switching at regular intervals the sample entry in one direction, the solvent entry in the opposite direction, whilst changing the analyte and waste takeoff positions appropriately as well.


title: Chromatography

text: Pyrolysis–gas chromatography–mass spectrometry is a method of chemical analysis in which the sample is heated to decomposition to produce smaller molecules that are separated by gas chromatography and detected using mass spectrometry.


title: Chromatography

text: Pyrolysis is the thermal decomposition of materials in an inert atmosphere or a vacuum. The sample is put into direct contact with a platinum wire, or placed in a quartz sample tube, and rapidly heated to 600–1000 °C. Depending on the application even higher temperatures are used. Three different heating techniques are used in actual pyrolyzers: Isothermal furnace, inductive heating (Curie Point filament), and resistive heating using platinum filaments. Large molecules cleave at their weakest points and produce smaller, more volatile fragments. These fragments can be separated by gas chromatography. Pyrolysis GC chromatograms are typically complex because a wide range of different decomposition products is formed. The data can either be used as fingerprints to prove material identity or the GC/MS data is used to identify individual fragments to obtain structural information. To increase the volatility of polar fragments, various methylating reagents can be added to a sample before pyrolysis.


title: Chromatography

text: Besides the usage of dedicated pyrolyzers, pyrolysis GC of solid and liquid samples can be performed directly inside Programmable Temperature Vaporizer (PTV) injectors that provide quick heating (up to 30 °C/s) and high maximum temperatures of 600–650 °C. This is sufficient for some pyrolysis applications. The main advantage is that no dedicated instrument has to be purchased and pyrolysis can be performed as part of routine GC analysis. In this case, quartz GC inlet liners have to be used. Quantitative data can be acquired, and good results of derivatization inside the PTV injector are published as well.


title: Chromatography

text: Fast protein liquid chromatography (FPLC), is a form of liquid chromatography that is often used to analyze or purify mixtures of proteins. As in other forms of chromatography, separation is possible because the different components of a mixture have different affinities for two materials, a moving fluid (the "mobile phase") and a porous solid (the stationary phase). In FPLC the mobile phase is an aqueous solution, or "buffer". The buffer flow rate is controlled by a positive-displacement pump and is normally kept constant, while the composition of the buffer can be varied by drawing fluids in different proportions from two or more external reservoirs. The stationary phase is a resin composed of beads, usually of cross-linked agarose, packed into a cylindrical glass or plastic column. FPLC resins are available in a wide range of bead sizes and surface ligands depending on the application.


title: Chromatography

text: Countercurrent chromatography (CCC) is a type of liquid-liquid chromatography, where both the stationary and mobile phases are liquids and the liquid stationary phase is held stagnant by a strong centrifugal force.


title: Chromatography

text: The operating principle of CCC instrument requires a column consisting of an open tube coiled around a bobbin. The bobbin is rotated in a double-axis gyratory motion (a cardioid), which causes a variable gravity (G) field to act on the column during each rotation. This motion causes the column to see one partitioning step per revolution and components of the sample separate in the column due to their partitioning coefficient between the two immiscible liquid phases used. There are many types of CCC available today. These include HSCCC (High Speed CCC) and HPCCC (High Performance CCC). HPCCC is the latest and best-performing version of the instrumentation available currently.


title: Chromatography

text: In the CPC (centrifugal partition chromatography or hydrostatic countercurrent chromatography) instrument, the column consists of a series of cells interconnected by ducts attached to a rotor. This rotor rotates on its central axis creating the centrifugal field necessary to hold the stationary phase in place. The separation process in CPC is governed solely by the partitioning of solutes between the stationary and mobile phases, which mechanism can be easily described using the partition coefficients ("K") of solutes. CPC instruments are commercially available for laboratory, pilot, and industrial-scale separations with different sizes of columns ranging from some 10 milliliters to 10 liters volume.


title: Chromatography

text: In contrast to Counter current chromatography (see above), periodic counter-current chromatography (PCC) uses a solid stationary phase and only a liquid mobile phase. It thus is much more similar to conventional affinity chromatography than to counter current chromatography. PCC uses multiple columns, which during the loading phase are connected in line. This mode allows for overloading the first column in this series without losing product, which already breaks through the column before the resin is fully saturated. The breakthrough product is captured on the subsequent column(s). In a next step the columns are disconnected from one another. The first column is washed and eluted, while the other column(s) are still being loaded. Once the (initially) first column is re-equilibrated, it is re-introduced to the loading stream, but as last column. The process then continues in a cyclic fashion.


title: Chromatography

text: Chiral chromatography involves the separation of stereoisomers. In the case of enantiomers, these have no chemical or physical differences apart from being three-dimensional mirror images. To enable chiral separations to take place, either the mobile phase or the stationary phase must themselves be made chiral, giving differing affinities between the analytes. Chiral chromatography HPLC columns (with a chiral stationary phase) in both normal and reversed phase are commercially available.


title: Chromatography

text: Conventional chromatography are incapable of separating racemic mixtures of enantiomers. However, in some cases "nonracemic" mixtures of enantiomers may be separated unexpectedly by conventional liquid chromatography (e. g. HPLC without chiral mobile phase or stationary phase ).


title: Chromatography

text: Aqueous normal-phase (ANP) chromatography is characterized by the elution behavior of classical normal phase mode (i.e. where the mobile phase is significantly less polar than the stationary phase) in which water is one of the mobile phase solvent system components. It is distinguished from hydrophilic interaction liquid chromatography (HILIC) in that the retention mechanism is due to adsorption rather than partitioning.


title: Chromatography

text: Chromatography is used in many fields including the pharmaceutical industry, the food and beverage industry, the chemical industry, forensic science, environment analysis, and hospitals.


title: National People's Congress

text: The National People's Congress of the People's Republic of China (NPC; ), or simply the National People's Congress, is constitutionally the supreme state authority and the national legislature of the People's Republic of China.


title: National People's Congress

text: With 2,980 members in 2018, it is the largest legislative body in the world. The National People's Congress meets in full session for roughly two weeks each year and votes on important pieces of legislation and personnel assignments among other things, and due to the temporary nature of the plenary sessions, most of NPC's power is delegated to the Standing Committee of the National People's Congress (NPCSC), which consists of about 170 legislators and meets in continuous bi-monthly sessions, when its parent NPC is not in session.


title: National People's Congress

text: As China is an authoritarian state, the NPC has been characterized as a rubber stamp for the Chinese Communist Party (CCP) or as only being able to affect issues of low sensitivity and salience to the Chinese regime. Most delegates to the NPC are officially elected by local people's congresses at the provincial level; local legislatures which are indirectly elected at all levels except the county-level. The CCP controls nomination and election processes at every level in the people's congress system, allowing it to stamp out any opposition.


title: National People's Congress

text: Membership to the congress is part-time in nature and carries no pay. Members of the National People's Congress are allowed to simultaneously hold seats in other bodies of government and the party and the NPC typically includes all of the senior officials in Chinese politics. However, membership of the Standing Committee is often full-time and carries a salary, and Standing Committee members are not allowed to simultaneously hold positions in executive, judicial, prosecutorial or supervisory posts. Under China's Constitution, the NPC is structured as a unicameral legislature, with the power to legislate and oversee the operations of the government, the supreme court, special committees, the supreme procuratorate, the central military commission and elect the major officers of state.


title: National People's Congress

text: The NPC is elected for a term of five years. It holds annual sessions every spring, usually lasting from 10 to 14 days, in the Great Hall of the People on the west side of Tiananmen Square in Beijing. The NPC's sessions are usually timed to occur with the meetings of the National Committee of the People's Political Consultative Conference (CPPCC), a consultative body whose members represent various social groups. As the NPC and the CPPCC are the main deliberative bodies of China, they are often referred to as the Lianghui (Two Sessions). According to the NPC, its annual meetings provide an opportunity for the officers of state to review past policies and to present future plans to the nation.


title: National People's Congress

text: A number of similar bodies of deliberation seeking to represent the people of China had been established prior to the founding of the People's Republic of China and prior to the National People's Congress. Notably, this includes the National Assembly and Legislative Yuan of the Republic of China, and the People's Political Consultative Conference of the People's Republic of China.


title: National People's Congress

text: Calls for a National Assembly were part of the platform of the revolutionaries who ultimately overthrew the Qing dynasty. In response, the Qing dynasty formed the first assembly in 1910, but it was virtually powerless and intended only as an advisory body.


title: National People's Congress

text: Following the Xinhai Revolution, national elections yielded the bicameral 1913 National Assembly, but significantly less than one percent voted due to gender, property, tax, residential, and literacy requirements. It was not a single nationwide election but a series of local elections that began in December 1912 with most concluding in January 1913. The poll was indirect, as voters chose electors who picked the delegates, in some cases leading to instances of bribery. The Senate was elected by the provincial assemblies. The president had to pick the 64 members representing Tibet, Outer Mongolia, and Overseas Chinese for practical reasons. However, these elections had the participation of over 300 civic groups and were the most competitive nationwide elections in the history of China.


title: National People's Congress

text: The election results gave a clear plurality for the Kuomintang (KMT), which won 392 of the 870 seats, but there was confusion as many candidates were members in several parties concurrently. Several switched parties after the election, giving the Kuomintang 438 seats. By order of seats, the Republican, Unity, and Democratic (formerly Constitutionalist) parties later merged into the Progressive Party under Liang Qichao.


title: National People's Congress

text: After the death of Yuan Shikai, the National Assembly reconvened on 1 August 1916 under the pretext that its three-year term had been suspended and had not expired, but President Li Yuanhong was forced to disband it due to the Manchu Restoration on 1 June 1917. 130 members (mostly Kuomintang) moved to Canton (Guangzhou) where they held an "extraordinary session" on 25 August under a rival government led by Sun Yat-sen, and another 120 quickly followed. After the Old Guangxi Clique became disruptive, the assembly temporarily moved to Kunming and later Chungking (Chongqing) under Tang Jiyao's protection until Guangzhou was liberated. Lacking a quorum, they selected new members in 1919.


title: National People's Congress

text: The original Legislative Yuan was formed in the original capital of Nanking (Nanjing) after the completion of the Northern Expedition. Its 51 members were appointed to a term of two years. The 4th Legislative Yuan under this period had its members expanded to 194, and its term in office was extended to 14 years because of the Second Sino-Japanese War (1937–45). According to KMT political theory, these first four sessions marked the period of political tutelage.


title: National People's Congress

text: The current Constitution of the Republic of China came into effect on 25 December 1947, and the first Legislative session convened in Nanking on 18 May 1948, with 760 members. Under the constitution, the main duty of the National Assembly was to elect the President and Vice President for terms of six years. It also had the right to recall the President and Vice President if they failed to fulfill their political responsibilities. According to "National Assembly Duties Act", the National Assembly could amend the constitution with a two-thirds majority, with at least three-quarters membership present. It could also change territorial boundaries. In addition to the National Assembly, it has two chambers of parliament that are elected. Governmental organs of the constitution follow the outline proposed by Sun Yat-sen and supported by the Kuomintang (Nationalist Party), while also incorporating the opinions of the federalism supported the Chinese Communist Party (CCP) in the 1940s. The separation of powers was designed by Carsun Chang, a founding member of the China Democratic League.


title: National People's Congress

text: As the mechanism is significantly different from the Western "trias politica", the grand justices has an interpretation which ruled that these three organs all bear characteristics equivalent to a "parliament".


title: National People's Congress

text: However, the government of the Republic of China lost the Chinese Civil War in 1949 and retreated to Taiwan. A set of temporary provisions were passed by the National Assembly to gather more powers to the President and limit the functions of the tricameral parliament. Members of the tricameral parliament elected in China in 1947 and 1948 were transplanted to Taipei. On 24 February 1950, 380 of 3,045 National Assembly members convened at the Sun Yat-sen Hall in Taipei and kept serving without reelection until 1991.


title: National People's Congress

text: After a series of constitutional amendments in the 1990s in Taiwan, the new Additional Articles of the Constitution have changed the Legislative Yuan to a unicameral parliament with democratically-elected members. The Control Yuan is now appointed by the President with the Legislative Yuan's approval, while the National Assembly was "de facto" abolished.


title: National People's Congress

text: The current National People's Congress can trace its origins to the Chinese Soviet Republic beginning in 1931 where the First National Congress of the Chinese Soviets of Workers', Peasants' and Soldiers' Deputies was held on November 7, 1931 in Ruijin, Jiangxi on the 14th anniversary of the October Revolution with another Soviet Congress that took place in Fujian on March 18, 1932, the 61st Anniversary of the Paris Commune. A Second National Congress took place from January 22 to February 1, 1934. During the event, only 693 deputies were elected with the Chinese Red Army taking 117 seats.


title: National People's Congress

text: In 1945 after World War II, the CCP and the Kuomintang held a Political Consultative Conference with the parties holding talks on post-World War II political reforms. This was included in the Double Tenth Agreement, which was implemented by the Nationalist government, who organised the first Political Consultative Assembly from January 10–31, 1946. Representatives of the Kuomintang, CCP, Chinese Youth Party, and China Democratic League, as well as independent delegates, attended the conference in Chongqing, temporary capital of China.


title: National People's Congress

text: A second Political Consultative Conference took place in September 1949, inviting delegates from various friendly parties to attend and discuss the establishment of a new state (PRC). This conference was then renamed the People's Political Consultative Conference. The first conference approved the Common Program, which served as the "de facto" constitution for the next five years. The conference approved the new national anthem, flag, capital city, and state name, and elected the first government of the People's Republic of China. In effect, the first People's Political Consultative Conference served as a constitutional convention. It was a "de facto" legislature of the PRC during the first five years of existence.


title: National People's Congress

text: The NPC is an authoritarian legislature. It has alternatively been characterized as a rubber stamp for the Chinese regime or as only being able to affect issues of low sensitivity and salience to the Chinese regime. According to Rory Truex, NPC "deputies convey citizen grievances but shy away from sensitive political issues, and the government in turn displays partial responsiveness to their concerns." According to the "New York Times," the NPC "is a carefully crafted pageant intended to convey the image of a transparent, responsive government." One of the NPC's members, Hu Xiaoyan, told the BBC in 2009 that she has no power to help her constituents. She was quoted as saying, "As a parliamentary representative, I don't have any real power."


title: National People's Congress

text: Under the constitution, the NPC is the highest organ of state power in China, and all four Chinese constitutions have granted it a large amount of lawmaking power. There are mainly four functions and powers of the NPC:


title: National People's Congress

text: Only the NPC has the power to amend the Constitution. Amendments to the Constitution must be proposed by the NPC Standing Committee or 1/5 or more of the NPC deputies. In order for the Amendments to become effective, they must be passed by 2/3 majority vote of all deputies. In contrast with other jurisdictions by which constitutional enforcement is considered a judicial power, in Chinese political theory, constitutional enforcement is considered a legislative power, and Chinese courts do not have the authority to determine constitutionality of legislation or administrative measures. Challenges to constitutionality have therefore become the responsibility of the National People's Congress which has a recording and review mechanism for constitutional issues


title: National People's Congress

text: The NPC's primary duty is the enactment of laws and making amendments of existing legislation governing criminal offenses, civil affairs, state organs and other matters of concern. To do this, the NPC acts in accordance with the Constitution and laws of the People's Republic in regards to its legislative activities. When the congress is in recess, its Standing Committee enacts all legislation presented to it by the CCP Central Committee, the State Council, the Central Military Commission, other government organs or by the deputies themselves either of the standing committee or those of the committees within the NPC.


title: National People's Congress

text: The NPC elects the President of the People's Republic of China and the Vice President of the People's Republic of China. The NPC also appoints several governmental executives like the Premier of the State Council and many other crucial officials to the central state organs. The NPC has the power to remove the above-mentioned officials from the office. The NPC also elects the chairman, Vice Chairmen, Secretary-General and other members of its Standing Committee. In the performance of its electoral responsibilities, the NPC acts as a de facto electoral college for the elections to the offices of the President and Vice President. During the first general plenary session of a new term of the Congress, all its deputies regardless of their representation as provincial or sectoral deputies serve as electors of the offices of the presidency and vice presidency. If the President or Vice President has been impeached by a majority vote of Congress, resigns or dies in office, the NPC, through the NPCSC, orders a special general plenary to be convened for the election to either office. If both offices are vacant during their terms of office, the procedure of its deputy-electors to elect new office holders is the same as in a usual first general plenary session.


title: National People's Congress

text: The NPC's other legislative work is creating legislation on, examining, and reviewing major national issues of concern presented to the Congress by either the CCP Central Committee, the State Council, or its own deputies. These include legislation on the report on the plan for national economic and social development and on its implementation, the national budget, and other matters. The Basic Laws of both the Hong Kong Special Administrative Region and the Macao Special Administrative Region, and the laws creating Hainan Province and Chongqing Municipality and the building of the Three Gorges Dam on the Yangtze River were all decided by the NPC. In performing these responsibilities either as a whole chamber or by its Standing Committee, the NPC acts in accordance with the Constitution and the laws of the People's Republic in acting on these issues in aid of legislation.


title: National People's Congress

text: The drafting process of NPC legislation is governed by the "Organic Law of the NPC" (1982) and the "NPC Procedural Rules" (1989). It begins with a small group, often of outside experts, who begin a draft. Over time, this draft is considered by larger and larger groups, with an attempt made to maintain consensus at each step of the process. By the time the full NPC or NPCSC meets to consider the legislation, the major substantive elements of the draft legislation have largely been agreed to. However, minor wording changes to the draft are often made at this stage. The process ends with a formal vote by the Standing Committee of the NPC or by the NPC in a plenary session.However, it is not completely without influence. It functions as a forum in which legislative proposals are drafted and debated with input from different parts of the government and outside technical experts. However, there are a wide range of issues for which there is no consensus within the Party and over which different parts of the party or government have different opinions. Over these issues the NPC has often become a forum for debating ideas and for achieving consensus.


title: National People's Congress

text: In practice, although the final votes on laws of the NPC often return a high affirmative vote, a great deal of legislative activity occurs in determining the content of the legislation to be voted on. A major bill such as the Securities Law can take years to draft, and a bill sometimes will not be put before a final vote if there is significant opposition to the measure.

text: One important constitutional principle which is stated in Article 8 of the Legislation Law of the People's Republic of China is that an action can become a crime only as a consequence of a law passed by the full NPC and that other organs of the Chinese government do not have the power to criminalize activity. This principle was used to overturn police regulations on custody and repatriation and has been used to call into question the legality of re-education through labor.In practice, there is no mechanism to verify constitutionality of statute laws, meaning that local administrations could bypass the constitution through Administrative laws.

text: The legislative process of the NPC works according to a five-year work plan drafted by the Legislative Affairs Commission Within the work plan, a specific piece of legislative is drafted by a group of legislators or administrative agencies within the State Council, these proposals are collected into a yearly agenda which outlines the work of the NPC in a particular year. This is followed by consultation by experts and approving in principle by the Communist Party. Afterwards, the legislation undergoes three readings and public consultation. The final approval is done in a plenary session in which by convention the vote is near unanimous.


title: National People's Congress

text: The NPC had never rejected a government bill until 1986, during the Bankruptcy Law proceedings, wherein a revised bill was passed in the same session. An outright rejection without a revised version being passed occurred in 2000 when a Highway Law was rejected, the first occurrence in sixty years of history. Moreover, in 2015, the NPC refused to pass a package of bills proposed by the State Council, insisting that each bill require a separate vote and revision process. The time for legislation can be as short as six months, or as long as 15 years for controversial legislation such as the Anti-Monopoly Law.


title: National People's Congress

text: The NPC meets for about two weeks each year at the same time as the Chinese People's Political Consultative Conference, usually in the Spring. The combined sessions have been known as the "two meetings." Between these sessions, power is exercised by the Standing Committee of the National People's Congress which contains about 170 members.


title: National People's Congress

text: The sessions have become media events because it is at the plenary sessions that the Chinese leadership produces work reports. Although the NPC has thus far never failed to approve a work report or candidate nominated by the Party, these votes are no longer unanimous. It is considered extremely embarrassing for the approval vote to fall below 70%, which occurred several times in the mid-1990s. More recently, work reports have been vetted with NPC delegates beforehand to avoid this embarrassment.


title: National People's Congress

text: In addition, during NPC sessions the Chinese leadership holds press conferences with foreign reporters, and this is one of the few opportunities Western reporters have of asking unscripted questions of the Chinese leadership.


title: National People's Congress

text: A major bill often takes years to draft, and a bill sometimes will not be put before a final vote if there is significant opposition to the measure. An example of this is the Property Law of the People's Republic of China which was withdrawn from the 2006 legislative agenda after objections that the law did not do enough to protect state property. China's laws are usually submitted for approval after at most three reviews at the NPC Standing Committee. However, the debate of the Property Law has spanned nine years, receiving a record seven reviews at the NPC Standing Committee and stirring hot debates across the country. The long-awaited and highly contested Property Law was finally approved at the Fifth Session of the Tenth National People's Congress (NPC) on 16 March 2007. Among the 2,889 deputies attending the closing session, 2,799 voted for it, 52 against it, 37 abstained and one did not vote.

text: The NPC consists of about 2,980 delegates in 2018, making it the largest parliamentary body in the world. Delegates to the National People's Congress are elected for five-year terms via a multi-tiered representative electoral system. Delegates are elected by the provincial people's assemblies, who in turn are elected by lower level assemblies, and so on through a series of tiers to the local people's assemblies which are directly elected by the electorate.


title: National People's Congress

text: Hong Kong has had a separate delegation since the 9th NPC in 1998, and Macau since the 10th NPC in 2003. The delegates from Hong Kong and Macau are elected via an electoral college rather than by popular vote, but do include significant political figures who are residing in the regions. The electoral colleges which elect Hong Kong and Macau NPC members are largely similar in composition to the bodies which elect the chief executives of those regions. In order to stand for election, the candidate must be validated by the Presidium of the electoral college and must agree to uphold the constitution of the PRC and the Basic Law. Each elector can vote for the number of seats from the qualified nominees.


title: National People's Congress

text: Under the one country, two systems policy, the CCP does not operate in Hong Kong or Macau, and none of the delegates from Hong Kong and Macau are formally affiliated with the CCP. However, the electoral committee which elects the Hong Kong and Macau delegates are mainly supporters of the pro-Beijing pan-establishment camp, and so far, all of the candidates that have been elected from Hong Kong and Macau are from the pro-Beijing pan-establishment camp.


title: National People's Congress

text: In contrast to Mainland China where political opposition parties are not allowed, the political opposition controls about one quarter of the electoral college, opposition candidates have been allowed to run for NPC seats, although no opposition candidate has ever been elected. In the most recent election in 2017, the pan-democrats opposition declined to endorse candidates because they believed that constitutional changes made getting a seat useless. In this election, the Presidium refused to allow the candidacy of several Occupy and pro-independence candidates on the grounds that they refused to sign the electoral form pledging to uphold the constitution and the Basic Law. However, the Presidium did allow the candidacy of several moderate pan-democratic figures who were unable to be elected.


title: National People's Congress

text: Although the pan-democratic opposition in Hong Kong does not have enough votes to elect an opposition candidate, they have expressed the belief that they have enough seats to influence which pro-Beijing figures can get elected.


title: National People's Congress

text: The current method of electing SAR delegations began after the handovers of sovereignty to the PRC. Between 1975 and the handovers, both Hong Kong and Macau were represented by delegations elected by the Guangdong Provincial Congress.


title: National People's Congress

text: The NPC has included a "Taiwan" delegation since the 4th NPC in 1975, in line with the PRC's position that Taiwan is a province of China. Prior to the 2000s, the Taiwan delegates in the NPC were mostly Taiwanese members of the Chinese Communist Party who fled Taiwan after 1947. They are now either deceased or elderly, and in the last three Congresses, only one of the "Taiwan" delegates was actually born in Taiwan (Chen Yunying, wife of economist Justin Yifu Lin); the remainder are "second-generation Taiwan compatriots", whose parents or grandparents came from Taiwan. The current NPC Taiwan delegation was elected by a "Consultative Electoral Conference" () chosen at the last session of the 11th NPC.


title: National People's Congress

text: The People's Liberation Army has had a large delegation since the founding of the NPC, making up anywhere from 4 percent of the total delegates (3rd NPC), to 17 percent (4th NPC). Since the 5th NPC, it has usually held about 9 percent of the total delegate seats, and is consistently the largest delegation in the NPC. In the 12th NPC, for example, the PLA delegation has 268 members; the next largest delegation is Shandong, with 175 members.


title: National People's Congress

text: For the first three NPCs, there was a special delegation for returned overseas Chinese, but this was eliminated starting in the 4th NPC, and although overseas Chinese remain a recognized group in the NPC, they are now scattered among the various delegations. The PRC also recognizes 55 minority ethnic groups in China, and there is at least one delegate belonging to each of these groups in the current (12th) NPC. These delegates frequently belong to delegations from China's autonomous regions, such as Tibet and Xinjiang, but delegates from some groups, such as the Hui people (Chinese Muslims) belong to many different delegations.


title: National People's Congress

text: The Hurun Report has tracked the wealth of some of the NPC's delegates: in 2018, the 153 delegates classed by the report as "super rich" (including China's wealthiest person, Ma Huateng) had a combined wealth of $650 billion. This was up from a combined wealth of $500 billion for the wealthiest 209 delegates in 2017, when (according to state media) 20% of delegates were private entrepreneurs. In 2013, 90 delegates were among the richest 1000 Chinese, each having a net worth of at least 1.8 billion yuan ($289.4 million). This richest 3% of delegates' average net worth was $1.1 billion (compared to an average net worth of $271 million for the richest 3% in the United States Congress at the time).


title: National People's Congress

text: In addition to the Standing Committee, nine special committees have been established under the NPC to study issues related to specific fields. These committees include:


title: National People's Congress

text: A number of administrative bodies have also been established under the Standing Committee to provide support for the day-to-day operation of the NPC. These include:


title: National People's Congress

text: The Presidium of the NPC is a 178-member body of the NPC. It is composed of senior officials of the Chinese Communist Party (CCP), the state, non-Communist parties and All-China Federation of Industry and Commerce, those without party affiliation, heads of central government agencies and people's organizations, leading members of all the 35 delegations to the NPC session including those from Hong Kong and Macao and the People's Liberation Army. It nominates the President and Vice President of China, the chairman, Vice-chairman, and Secretary-General of the Standing Committee of the NPC, the Chairman of the Central Military Commission, and the President of the Supreme People's Court for election by the NPC. Its functions are defined in the "Organic Law of the NPC", but not how it is composed.


title: National People's Congress

text: Under the Constitution of the People's Republic of China, the Chinese Communist Party is guaranteed a leadership role, and the National People's Congress therefore does not serve as a forum of debate between government and opposition parties as is the case with Western parliaments. At the same time, the Constitution makes the Party subordinate to laws passed by the National People's Congress, and the NPC has been the forum for debates and conflict resolution between different interest groups. The Communist Party maintains control over the NPC by controlling delegate selection, maintaining control over the legislative agenda, and controlling the constitutional amendment process.


title: National People's Congress

text: The ruling Chinese Communist Party maintains control over the composition of people's congresses at various levels, especially the National People's Congress. At the local level, there is a considerable amount of decentralization in the candidate preselection process, with room for local in-party politics and for participation by non-Communist candidates. The structure of the tiered electoral system makes it difficult for a candidate to become a member of the higher level people's assemblies without the support from politicians in the lower tier, while at the same time making it impossible for the party bureaucracy to completely control the election process.


title: National People's Congress

text: One such mechanism is the limit on the number of candidates in proportion to the number of seats available. At the national level, for example, a maximum of 110 candidates are allowed per 100 seats; at the provincial level, this ratio is 120 candidates per 100 seats. This ratio increases for each lower level of people's congresses, until the lowest level, the village level, has no limit on the number of candidates for each seat. However, the Congress website says "In an indirect election, the number of candidates should exceed the number to be elected by 20% to 50%." The practice of having more candidates than seats for NPC delegate positions has become standard, and it is different from Soviet practice in which all delegates positions were selected by the Party center. Although the limits on member selection allows the Party leadership to block candidates it considers unacceptable, it also causes unpopular candidates to be removed in the electoral process. Direct and explicit challenges to the rule of the Communist Party are not tolerated, but are unlikely in any event due to the control the party center has on delegate selection.


title: National People's Congress

text: Furthermore, the constitution of the National People's Congress provides for most of its power to be exercised on a day-to-day basis by its Standing Committee. Due to its overwhelming majority in the Congress, the Communist Party has total control over the composition of the Standing Committee, thereby allowing it to control actions of the National People's Congress. However, the Communist Party uses the National People's Congress as a mechanism to coordinate different interests, weigh different strategies and incorporate these views into draft legislation.


title: National People's Congress

text: Although Party approval is in effect essential for membership in the NPC, approximately a third of the seats are by convention reserved for non-Communist Party members. This includes technical experts and members of the smaller allied parties. While these members do provide technical expertise and a somewhat greater diversity of views, they do not function as a political opposition.


title: National People's Congress

text: Under Chinese law, the Communist Party is barred from directly introducing legislation into the NPC. The primary role of the Communist Party in the legislative process largely is exercised during the drafting phase of the legislation. Before the NPC considers legislation, there are working groups which study the proposed topic, and it is necessary for the Party leadership to agree "in principle" to any legislative changes. This process overlaps with the early drafting phase as particularly controversial or sensitive issues requires approval and consensus from the Party leadership.


title: National People's Congress

text: The Communist Party leadership plays a particularly large role in the approval of constitutional amendments. In contrast to ordinary legislation, which the Communist Party leadership approves the legislation in principle, and in which the legislation is then introduced by government ministers or individual National People's Congress members, constitutional amendments are drafted and debated within the Communist Party, approved by the Central Committee of the Party and then presented to the National People's Congress. In contrast to ordinary legislation, in which the process is largely directed by the Legislation Law, the process for constitutional revision is largely described by Party documents. Unlike ordinary legislation in which the NPC routinely makes extensive revisions to legislative proposals which have been introduced to it, the changes to constitutional amendments from the draft approved by the party have been minor.


title: National People's Congress

text: In addition to passing legislation, the NPCSC interacts with local governments through its constitutional review process. In contrast to most Western nations, constitutional review is considered a legislative function and not a judicial one, and Chinese courts are not allowed to examine the constitutionality of legislation. The NPC has created a set of institutions which monitor local administrative measures for constitutionality. Typically, the Legislative Affairs Committee will review legislation for constitutionality and then inform the enacting agencies of its findings, and rely on the enacting agency to reverse its decision. Although the NPC has the legal authority to annul unconstitutional legislation by a local government, it has never used that power.


title: The Maltese Falcon (1941 film)

text: The Maltese Falcon is a 1941 American film noir written and directed by John Huston in his directorial debut, based on the 1930 novel of the same name by Dashiell Hammett and indebted to the 1931 movie of the same name. It stars Humphrey Bogart as private investigator Sam Spade and Mary Astor as his "femme fatale" client. Gladys George, Peter Lorre and Sydney Greenstreet co-star, with the last appearing in his film debut. The story follows a San Francisco private detective and his dealings with three unscrupulous adventurers, all of whom are competing to obtain a jewel-encrusted falcon statuette.


title: The Maltese Falcon (1941 film)

text: The film premiered in New York City on October 3, 1941, and was nominated for three Academy Awards. Considered one of the greatest films of all time, it was one of the first 25 films selected by the Library of Congress to be included in the National Film Registry for being "culturally, historically, or aesthetically significant". It is a part of Roger Ebert's series "The Great Movies" and was cited by "Panorama du Film Noir Américain" as the first major film noir.


title: The Maltese Falcon (1941 film)

text: In San Francisco in 1941, private investigators Sam Spade and Miles Archer meet prospective client Ruth Wonderly. She claims to be looking for her missing sister, who ran off from their home in New York and came to the city with a man named Floyd Thursby. Archer agrees to help get her sister back. However, later that night, the police inform Spade that Archer has been killed. Spade tries calling his client at her hotel to discover she has checked out. Back at his apartment, he is grilled by Police Detective Tom Polhaus and Lieutenant Dundy, who tell him that Thursby was murdered the same evening. Dundy suggests that Spade had the opportunity and motive to kill Thursby, who likely killed Archer.


title: The Maltese Falcon (1941 film)

text: Later that morning, Spade meets his client. Now calling herself Brigid O'Shaughnessy, she confesses to creating the story and convinces Spade to investigate the murders. She also reveals Thursby was her partner. He took advantage of her and probably killed Archer, but she claims to have no idea who killed Thursby. At his office, Spade meets Joel Cairo, who first offers him $5,000 to find a "black figure of a bird". When Spade is skeptical, Cairo pulls a gun on him and searches the room for it. Spade knocks Cairo out and goes through his belongings. When Cairo comes round, he hires Spade.


title: The Maltese Falcon (1941 film)

text: As he goes to visit O'Shaughnessy later that evening, he is followed by a young man on the way there, but manages to evade him. When he tells her about Cairo, her nervousness indicates she knows him. He arranges a meeting between the two at his apartment, where Cairo becomes agitated when O'Shaughnessy reveals that the "Fat Man" is in San Francisco. When Spade goes to Cairo's hotel in the morning, he spots the young man following him earlier. His name is Wilmer, and he works for Kasper Gutman, the "Fat Man". In his hotel suite, Gutman relates the history of the Maltese Falcon, then offers Spade his pick of $25,000 for the bird and another $25,000 after its sale, or a quarter of the proceeds from its sale. After Spade passes out because his drink is spiked, Wilmer and Cairo come in from another room and leave with Gutman.


title: The Maltese Falcon (1941 film)

text: On coming round, Spade searches the suite and finds a newspaper with the arrival time of the freighter "La Paloma" circled. He goes to the dock, only to find the ship on fire. Later, the ship's captain, Jacoby, shot several times, staggers into Spade's office before dying. The bundle he was clutching contains the Maltese Falcon. O'Shaughnessy calls the office, gives an address, then screams before the line goes dead.


title: The Maltese Falcon (1941 film)

text: Spade stashes the package at the bus terminal, then goes to the address, which turns out to be an empty lot. Spade returns home to find O'Shaughnessy hiding in a doorway. He takes her inside and finds Gutman, Cairo, and Wilmer waiting for him, guns drawn. Gutman gives Spade $10,000 for the Falcon, but Spade tells them that part of his price is someone he can turn over to the police for the murders of Thursby and Captain Jacoby, suggesting Wilmer, who, Gutman confirms, actually did shoot both. After some intense negotiation, Gutman and Cairo agree and Wilmer is knocked out and disarmed.


title: The Maltese Falcon (1941 film)

text: Just after dawn, Spade calls his secretary, Effie Perine, to bring him the bundle. However, when Gutman inspects the statuette, he finds it is a fake and Wilmer escapes during the tumult. Recovering his composure, Gutman invites Cairo to return with him to Istanbul to continue their quest. After they leave, Spade calls the police and tells them where to pick up the pair. Spade then angrily confronts O'Shaughnessy, telling her he knows she killed Archer to implicate Thursby, her unwanted accomplice. She confesses, but begs Spade not to turn her over to the police. Despite his feelings for her, Spade gives O'Shaughnessy up.


title: The Maltese Falcon (1941 film)

text: Hammett had once worked as a private detective for the Pinkerton Detective Agency in San Francisco, and he used his birth name "Samuel" for the story's protagonist. He wrote of the book's main character in 1934:


title: The Maltese Falcon (1941 film)

text: Spade has no original. He is a dream man in the sense that he is what most of the private detectives I worked with would like to have been, and, in their cockier moments, thought they approached.


title: The Maltese Falcon (1941 film)

text: Other characters in "The Maltese Falcon" were based on people whom he met or worked with during that time. The character of sinister "Fat Man" Kasper Gutman was based on Maundy Gregory, an overweight British detective-entrepreneur who was involved in many sophisticated endeavors and capers, including a search for a long-lost treasure like the jeweled Falcon. The character of Joel Cairo was based on a criminal whom Hammett arrested for forgery in Pasco, Washington, in 1920.
