James Dewey Watson was born in Chicago, Ill., on April 6, 1928. He attended Horace Mann Grammar School and then South Shore High School. At the age of 15, he transferred to the University of Chicago in an experimental scholarship program for gifted youngsters. A lifelong interest in birds led him to study biology, and he was awarded his Bachelor of...
Watson and Crick decided to use a model-building approach to try to discern the molecular structure of the DNA molecule. Both were convinced that understanding the molecular geometry would be central to discovering how DNA could transmit genetic information from parent to daughter cells. The men understood that discovering the structure of the DNA ...
Watson and Crick used the new information to construct a new double-stranded helix model with the nitrogen bases paired A to T and C to G in the center. This base pairing immediately suggested to Crick that one side of the molecule could serve as a template to exactly replicate DNA sequences to pass on genetic information during cell reproduction. ...
In 1968, Watson became the director of the Cold Spring Harbor Laboratory. At the time, the institution was struggling financially, but Watson proved to be very good at raising funds for research. Under Watson’s leadership, Cold Spring became one of the world’s leading institutions for research in molecular biology. In 1990, Watson was named head of...

James Dewey Watson is an American geneticist and biophysicist. He is noted for his decisive work in the discovery of the molecular structure of DNA, the hereditary material associated with the transmission of genetic information. He shared the Nobel Prize for Physiology or Medicine with Francis Crick and Maurice Wilkins in 1962.
Mar 3, 2022 · James Watson became a Senior Research Fellow in Biology at the California Institute of Technology, before returning to Cambridge in 1955. The following year he moved to Harvard University, where he became Professor of Biology, a post he held until 1976.
The Nobel Prize in Physiology or Medicine 1962 was awarded jointly to Francis Harry Compton Crick, James Dewey Watson and Maurice Hugh Frederick Wilkins "for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material"
