James D. Watson

The Double Helix

1. IDEA 1

   Discovery was a race

   Watson tells his personal story of how he and Francis Crick discovered the structure of DNA in 1953. He presents science as a competitive race, full of ambition, rivalry and luck.

2. IDEA 2

   Two young scientists teamed up

   Watson describes meeting Crick at Cambridge, where they shared an obsession with understanding DNA. Their very different personalities, he says, worked well together. Together, they kept pushing each other to try new ideas and drop weak ones.

3. IDEA 3

   Franklin's images were crucial

   Watson describes the X-ray images of DNA produced by Rosalind Franklin at King's College London. One image, often called Photo 51, gave key clues about DNA's helical shape. Her careful work gave the evidence that the model had to match.
