Rosalind Franklin had seen the helix: A forgotten photograph rewrites the history of DNA’s structure
For decades, one of the best-known stories in science was told like a movie. In 1953, at the age of 23, James Watson visited Maurice Wilkins’s laboratory at King’s College London. There, Wilkins showed him a photograph of DNA taken by Rosalind Franklin, and Watson had an epiphany. “The instant I saw the picture my mouth fell open and my pulse began to race,” Watson wrote in The Double Helix: A Personal Account of the Discovery of the Structure of DNA, the book in which he recounted, 15 years later, how he and Francis Crick unraveled the structure of DNA.
