Watson and Crick, discoverers of the structure of DNA. James Watson (b.1928, left) and Francis Crick (1916-2004), with their model of part of a DNA molecule in 1953. Watson and Crick met at the Cavendish Laboratory, Cambridge, in 1951. Their work on DNA was performed with a knowledge of Chargaff's ratios of the bases in DNA and access to the X-ray crystallography of Maurice Wilkins and Rosalind Franklin at King's College London. Combining this knowledge led to the deduction that DNA exists as a double helix. Crick, Watson and Wilkins shared the 1962 Nobel Prize for Physiology or Medicine, Franklin having died in 1958. Photographed in the Cavendish Laboratory, University of Cambridge, UK, in May 1953.
