Rosalind Franklin captured Photo 51 in 1952—an extraordinary X-ray image that clearly showed DNA’s spiral shape, even revealing key measurements like the 3.4 Å spacing between bases. Her data was crucial to understanding DNA’s structure. But Maurice Wilkins shared the image and her unpublished findings with Watson without her knowledge or consent. Watson later described seeing it as a breakthrough moment. Watson and Crick published the double-helix model in Nature in 1953 and became famous. In 1962, they and Wilkins received the Nobel Prize. Franklin had died of ovarian cancer in 1958 at just 37. Her own paper appeared alongside theirs, yet most recognition passed her by.
Her work laid the foundation for modern genetics, yet she never received the credit she truly deserved.
