Photo 51 (1952)

In 1952, Rosalind Franklin and Raymond Gosling obtained Photo 51, a key image of DNA's structure.

In 1952, Rosalind Franklin and Raymond Gosling, at King's College London, obtained through X-ray diffraction the photograph known as Photo 51.

The image showed an X-shaped pattern characteristic of a helical structure and provided the molecule's dimensions, data that proved decisive for proposing the DNA double helix model.

The video recounts that Franklin perfected the X-ray diffraction technique until she achieved, after 100 hours of radiation exposure, this photograph, and explains that her colleague Maurice Wilkins showed it without permission to James Watson, who together with Francis Crick built his model from that data.
