Franklin is best known for her work on the X-ray diffraction images of DNA while at King's College London, particularly Photo 51, taken by Franklin's student Raymond Gosling, which led to the discovery of the DNA double helix for which Francis Crick, James Watson, and Maurice Wilkins shared the Nobel Prize in Physiology or Medicine in 1962. Watson suggested that Franklin would have ideally been awarded a Nobel Prize in Chemistry, along with Wilkins but, although there was not yet a rule against posthumous awards, the Nobel Committee generally did not make posthumous nominations.
