Francis Crick his skills in the analysis of X-ray diffraction data for proteins, working primarily on ribonuclease and the mechanisms of protein synthesis. David Harker, the American X-ray crystallographer, was described as "the John Wayne of crystallography" by Vittorio Luzzati, a crystallographer at the Centre for Molecular Genetics in Gif-sur-Yvette near Paris, who had worked with Rosalind Franklin. After the discovery of the double helix model of DNA, Crick's interests quickly turned to the biological implications of the structure. In 1953, Watson and Crick published another article in "Nature" which stated: "it therefore seems likely that the precise sequence of the bases
Raymond Gosling of x-ray diffraction photography of DNA and obtained at the time the sharpest diffraction images of DNA. Gosling made the X-ray diffraction image of DNA known as "Photograph 51". This work led directly to the 1962 Nobel Prize for Physiology or Medicine being awarded to Francis Crick, James D. Watson and Maurice Wilkins. Gosling was the co-author with Franklin of one of the three DNA double helix papers published in "Nature" in April 1953. His other King's colleagues included Alex Stokes and Herbert Wilson. Gosling briefly remained at King's College following the completion of his thesis in 1954 before lecturing
