Cultural Note

The Double Helix, a memoir (1968) by James D. Watson. In this personal account of the landmark discovery of the structure of the DNA molecule in 1953, for which Watson later shared a Nobel Prize with Francis Crick and Maurice Wilkins, scientific research is shown to be a competitive race in which ego, politics, and luck play prominent roles. Watson's less than generous treatment of Maurice Wilkins' and Rosalind Franklin's contribution to his work caused much controversy when the book was published.
