Francis Crick DNA crystals revealed to Crick that the two DNA strands were antiparallel. In January 1953, Watson was shown an X-ray photograph of B-DNA (called photograph 51), by Wilkins. Wilkins had been given photograph 51 by Rosalind Franklin's Ph.D. student Raymond Gosling. Wilkins and Gosling had worked together in the Medical Research Council's (MRC) Biophysics Unit before director John Randall appointed Franklin to take over both DNA diffraction work and guidance of Gosling's thesis. It appears that Randall did not communicate effectively with them about Franklin's appointment, contributing to confusion and friction between Wilkins and Franklin. In the middle of February
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
