Peter McCullough Peter R. McCullough ( ; born August 20, 1964, Providence, Rhode Island) is an American astronomer, founder of the XO Project and discoverer of extrasolar transiting planets, such as XO-1b. Soon after the U.S. declassification of the laser beacon adaptive optics technique in 1991, he identified dusty disks around newborn stars, later referred to as proplyds, in observations of the Orion Nebula made with the Starfire Optical Range. Astronomers John Gaustad, McCullough, and David Van Buren with engineer Wayne Rosing mapped the entire southern sky in the hydrogen alpha transition with sufficient sensitivity for decontamination of the Milky Way from the cosmic microwave background. McCullough's modification to the Stromgren sphere model often produces more realistic results than the original.

André-Adolphe-Eugène Disdéri André-Adolphe-Eugène Disdéri (] ; 28 March 1819 – 4 October 1889) was a French photographer who started his photographic career as a daguerreotypist but gained greater fame for patenting his version of the "carte de visite," a small photographic image which was mounted on a card. Disdéri, a brilliant showman, made this system of mass-production portraiture world famous.

John Iliopoulos John Iliopoulos (Greek: Ιωάννης Ηλιόπουλος; 1940, Kalamata, Greece) is a Greek physicist and the first person to present the Standard Model of particle physics in a single report. He is best known for his prediction of the charm quark with Sheldon Lee Glashow and Luciano Maiani (the "GIM mechanism"). Iliopoulos is also known for demonstrating the cancelation of anomalies in the Standard model. He is further known for the Fayet-Iliopoulos D-term formula, which was introduced in 1974. He is currently an honorary member of Laboratory of theoretical physics of École Normale Supérieure, Paris.

John Linsley John David Linsley (12 March 1925 – 25 September 2002) was an American physicist who performed pioneering research on cosmic rays, particularly ultra-high-energy cosmic rays. He did his most significant work from 1959 to 1978 using a ground-based array of detectors at Volcano Ranch in New Mexico. He is best known for being the first to detect an air shower created by a primary particle with an energy of 10 eV. This was the highest energy cosmic ray observed up to that point. Linsley's observations suggested that not all cosmic rays are confined within the galaxy and showed the first evidence of a flattening of the cosmic ray spectrum at energies above 10 eV.

John William Draper John William Draper (May 5, 1811 – January 4, 1882) was an English-American scientist, philosopher, physician, chemist, historian and photographer. He is credited with producing the first clear photograph of a female face (1839–40) and the first detailed photograph of the moon in 1840. He was also the first president of the American Chemical Society (1876–77) and a founder of the New York University School of Medicine. One of Draper's books, the "History of the Conflict between Religion and Science", popularised the conflict thesis proposing intrinsic hostility in the relationship between religion and science. It was widely read, and was translated into several languages. His son, Henry Draper, and his granddaughter, Antonia Maury, were astronomers, her younger sister, Carlotta Maury was a paleontologist, and his eldest son, John Christopher Draper, was a chemist.

Jack Oliver (scientist) John "Jack" Ertle Oliver (September 26, 1923 – January 5, 2011) was an American scientist. Oliver, who earned his PhD. at Columbia University in 1953, studied earthquakes and ultimately provided seismic evidence supporting plate tectonics. In the 1960s, Oliver and his former graduate student, Bryan Isacks, set up seismographic stations in the South Pacific to record earthquake activity, and the data collected led to the insight that part of the ocean floor was being pushed downward.

Xerography Xerography or electrophotography is a dry photocopying technique. Its fundamental principle was invented by Hungarian physicist Pál Selényi and based on Selényi's publications Chester Carlson applied for and was awarded U.S. Patent  on October 6, 1942. The technique was originally called electrophotography. It was later renamed xerography—from the Greek roots ξηρός "xeros", "dry" and -γραφία "-graphia", "writing"—to emphasize that, unlike reproduction techniques then in use such as cyanotype, this process used no liquid chemicals.
