Watson is a U.S. molecular biologist, geneticist and zoologist, best known as one of the co-discoverers of the structure of DNA in 1953 with Francis Crick. In 1998, the Modern Library placed The Double Helix at number 7 on its list of the 100 best nonfiction books of the 20th century.
Watson and Crick used many aluminium templates like this one, which is the single base Adenine (A), to build a physical model of DNA in 1953. When Watson and Crick produced their double helix model of DNA, it was known that most of the specialized features of the many different life forms on Earth are made possible by proteins.
The inscription on the helices of a DNA sculpture (which was donated by James Watson) outside Thirkill Court, Clare College, Cambridge, reads: "The structure of DNA was discovered in 1953 by Francis Crick and James Watson while Watson lived here at Clare." and on the base: "The double helix model was supported by the work of Rosalind Franklin ...
DNA model built by Crick and Watson in 1953, in the Science Museum, London. In mid-March 1953, Watson and Crick deduced the double helix structure of DNA. [11] Crucial to their discovery were the experimental data collected at King's College London—mainly by Rosalind Franklin for which they did not provide proper attribution.

Watson and Crick completed their model, which is now accepted as the first correct model of the double helix of DNA. On 28 February 1953 Crick interrupted patrons' lunchtime at The Eagle pub in Cambridge, England to announce that he and Watson had "discovered the secret of life".

February 15 – Linus Pauling proposes a DNA triple helix structure, [1] which is rapidly shown to be incorrect. 25 April 1953: the DNA double helix is first formally described. February 28 – Francis Crick and James Watson enter The Eagle, Cambridge, for a pub lunch announcing "We have discovered the secret of life." [2]
In 1953, James Watson and Francis Crick discovered the double helical structure of the DNA molecule based on the discoveries made by Rosalind Franklin. [5] In 1961, François Jacob and Jacques Monod demonstrated that the products of certain genes regulated the expression of other genes by acting upon specific sites at the edge of those genes.
