Despite what Watson said, Rosalind Franklin understood structure of DNA first

A new study published in the journal Nature Methods has shed new light on the discovery of the structure of DNA, crediting Rosalind Franklin with understanding the structure before James Watson and Francis Crick. Researchers analyzed the unpublished notebooks of Franklin, a British biophysicist and X-ray crystallographer, and found that she had solved the structure of DNA before the famous 'Photograph 51' image, which is often credited with helping Watson and Crick determine the double helix model. Franklin's notebooks revealed that she had worked out the structure of DNA in 1952, but her work was not widely recognized at the time.
