Francis crick

Francis crick --> Crick, Francis

(Science: person) An english biologist born in 1916 who was one of three people to win the Nobel Prize in 1962 for the category of physiology or medicine. He and James Watson, an American biochemist and alumnus of Indiana university, discovered the double-stranded helix structure of the dna molecule and built the Watson-Crick model of this structure.

Their work was heavily based on the work of Maurice Wilkins (who also won the Nobel Prize in physiology or medicine in 1962) and Rosalind Franklin (who died before the 1962 Nobel Prize winners were selected). The model they postulated is the accepted model used today.

Lived: 1916-
