DNA diffraction image (labeled as "Photo 51") taken by Rosalind Franklin and Raymond Gosling in May 1952, and the information that the DNA bases are paired. On 28 February 1953 Crick interrupted patrons' lunchtime at The Eagle pub in Cambridge to announce that he and Watson had "discovered the secret of life". Months earlier, in February 1953, Linus Pauling and Robert Corey proposed a model for nucleic acids containing three intertwined chains, with the phosphates near the axis, and the bases on the outside. Experimental evidence supporting the Watson and Crick model was published in a series of five articles in
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
