James Watson and Francis Crick
The Discovery of DNA's Structure. Taken in 1952, this image is the first X-ray picture of DNA, which led to the discovery of its molecular structure by Watson and Crick. Created by Rosalind Franklin using a technique called X-ray crystallography, it revealed the helical shape of the DNA molecule. Watson and Crick realized that DNA was made up of two chains of nucleotide pairs that encode the genetic information for all living things.

For their work, Watson, Crick, and Wilkins received the Nobel Prize in 1962. Despite her contribution to the discovery of DNA's helical structure, Rosalind Franklin was not named a prize winner: She had died of cancer four years earlier, at the age of 37. Watson and Crick realized that DNA was made up of two chains of nucleotide pairs that encode the genetic information for all living things.

James Watson and his British colleague Francis Crick discovered the double helix structure of DNA. For this fundamental finding James, Francis and Maurice Wilkins were awarded the Nobel Prize for Physiology or Medicine in 1962. Unravelling the double helix Stories The discovery of the structure of DNA by James Watson and Francis Crick in 1953 is one of the most famous scientific discoveries of all time. Unravelling the double helix Stories. It is a common misconception that James Watson and Francis Crick discovered DNA in the 1950s. In reality, DNA was discovered decades before. It was by following the work of the pioneers before them that James and Francis were able to come to their ground-breaking conclusion about the structure of DNA in 1953. Unravelling the double helix Stories The discovery of the structure of DNA by James Watson and Francis Crick in 1953 is one of the most famous scientific discoveries of all time. Unravelling the double helix Stories. Instead, it was Franklin's famous photograph 51 that finally revealed the helical structure of DNA to Watson and Crick in 1953. This picture of DNA that had been crystallized under moist conditions shows a fuzzy X in the middle of the molecule, a pattern indicating a helical structure. It appeared in April 1953 in the scientific paper where James Watson and Francis Crick presented the structure of the DNA-helix, the molecule that carries genetic information from one generation to the other. A+E Networks. On this day in 1953, Cambridge University scientists James D. Watson and Frances H.C. Crick announce that they have determined the double-helix structure of DNA, the molecule containing human genes. The discovery of DNA by James Watson and Frances Crick being a major one for the scientific community. Not only was DNA discovered on this day, but the Republican Party was founded in Wisconsin. Fifty years ago, James Watson and Francis Crick announced to patrons in a Cambridge pub that they had just discovered the secret of life. Their discovery was that the DNA double helix explained how cells divide and develop.  Francis Crick and his American colleague, James Watson, discovered the double helix structure of DNA. For this fundamental finding Francis, James and Maurice Wilkins were awarded the Nobel Prize for Physiology or Medicine in 1962.

Unravelling the double helix Stories. James Watson and Francis Crick, 1959 © Crick and Watson, together with Maurice Wilkins, won the 1962 Nobel Prize in Medicine for their discovery of the structure of DNA. This was one of the most significant scientific discoveries of the 20th century. Francis Harry Compton Crick was born on 8 June 1916 near Northampton. Crick and Watson used their findings in their own research. In April 1953, they published the news of their discovery, a molecular structure of DNA based on all its known features-the double helix.
