Photo 51

Popular accounts of the discovery of DNA's structure claim Rosalind Franklin failed to grasp the significance of her famous Photo 51, crediting James Watson alone with the insight. A new paper by science historian Alistair Sponsel and a crystallographer revisits that narrative, arguing Franklin's own role in interpreting the evidence has been understated and the traditional story distorts how the breakthrough actually happened.

A new analysis revisits the long-standing claim that Rosalind Franklin failed to recognize the significance of her famous Photo 51 of DNA, concluding she did in fact understand the molecule was a helix. The piece challenges the familiar narrative that James Watson and Francis Crick alone grasped the structure while Franklin overlooked her own evidence, reigniting debate over how credit for the 1953 discovery was分配ed.

A new Science article revisits the claim that Rosalind Franklin failed to grasp the significance of Photo 51, her famous DNA diffraction image. The piece argues she did not miss the double helix at all, challenging the long-standing narrative about her role in the discovery alongside Watson and Crick. Readers are debating her historical credit and how the story of the 1953 breakthrough has been told.
