Revisiting Rosalind Franklin's Contribution to DNA Discovery.

Researchers argue that the popular narrative of Rosalind Franklin's X-ray diffraction image, Photo 51, being illicitly shown to James Watson, revealing to him that DNA has a double helix and allowing him and his colleague Francis Crick to deduce the structure and claim the glory, is far from the key to the puzzle. Instead, the success of Watson and Crick was down to trial and error with calculations and cardboard models, with the importance of Photo 51 augmented by Watson in his 1968 book, The Double Helix, to add drama to the tale of the discovery.
