Photography 51
One of the X-ray diffraction images that Rosalind has marked a milestone in the history of biology, in it the helical shape of the DNA strands can be seen. Without permission, his co-worker Wilkins takes the liberty of showing the snapshot to Watson, who later claimed to have been left “speechless” see it.
photography 51 is the confirmation of the theory of Watson and Crick, who are in a hurry to publish it in 1953, a marginal mention Rosalind Franklin, Part of the work also appears in the same edition of Nature. Later Arthur Kornberg, disciple of Severo Ochoa, would provide definitive experimental evidence of the model’s accuracy (by receiving the Nobel Prize for Medicine 1959 along with his mentor). [2]
photography 51. The authors are identified on the right: Franklin i Gosling
Raymond Gosling, a 1950 graduate student, supervised by Maurice Wilkins, took an X-ray photograph of a DNA fiber, the image that inspired the young James Watson when Wilkins was presented to a conference in Naples. The most famous “photo 51” was taken in May 1952 Gosling also, Already at that time assigned to Rosalind Franklin [3]
