James D Watson

Scarce ballpoint sketch of a DNA strand on a 6.5 x 3.5 envelope from the Cold Spring Harbor Laboratory, signed “James D. Watson.” In very fine condition. Particularly elusive in uninscribed examples.

James Dewey Watson KBE (born April 6, 1928) is an American molecular biologist, geneticist and zoologist. In 1953, he co-authored with Francis Crick the academic paper proposing the double helix structure of the DNA molecule. Watson, Crick and Maurice Wilkins were awarded the 1962 Nobel Prize in Physiology or Medicine "for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material".
