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.
These four scientistsâWatson, Crick, Franklin, and Wilkinsâcodiscovered the double-helix structure of DNA, which formed the basis for modern biotechnology. Home / Learn / Historical Biographies At Kingâs College London, Rosalind Franklin obtained images of DNA using X-ray crystallography, an idea first broached by Maurice Wilkins. Franklinâs images allowed James Watson and Francis Crick to create their famous two-strand, or double-helix, model. In 1962 Watson (b. 1928), Crick (1916â2004), and Wilkins (1916â2004) jointly received the Nobel Prize in Physiology or Medicine for their 1953 determination of the structure of deoxyribonucleic acid (DNA).
