Francis Crick (1916-2004), British molecular biologist and co- discoverer of the structure of DNA. Crick's education was in physics, but after World War 2 he moved to Cambridge and took up molecular biology. Crick met James Watson in 1951, the two agreeing to study the structure of DNA as the basis of the genetic code. Basing their theories on existing work, as well as the crystallography of Wilkins & Franklin, the two announced their 'double helix' structure in 1953. Crick, Watson and Wilkins shared the 1962 Nobel Prize for Physiology or Medicine. Crick's later work revolved around the way DNA codes for proteins. Photographed in 1993.
