James Dewey Watson is an American geneticist who, with Francis Crick, discovered the double helical structure of the DNA molecule. For this work he received the Nobel Prize for Medicine in 1962 together with Crick and Maurice Wilkins. His personal and informal account of this discovery "The Double Helix" aroused some controversy with its frank account of the fiercely competitive nature of scientific research. In particular, he revealed that the crucial breakthrough was based on the work of Rosalind Franklin, and her unpublished experimental results were used without her knowledge or permission. Franklin died before the Nobel Prize was awarded.
In 1968 he became director of the Cold Spring Harbor Laboratory in Long Island NY and in from 1988 helped direct The Human Genome Project
