James D. Watson (1928–2025) was an American molecular biologist and geneticist who, together with Francis Crick, proposed the double-helix structure of DNA in 1953, drawing upon crucial X-ray diffraction research by Rosalind Franklin and others. Watson shared the 1962 Nobel Prize in Physiology or Medicine with Crick and Maurice Wilkins for discoveries concerning the molecular structure of nucleic acids. One of the most consequential scientific breakthroughs of the 20th century, their work helped establish the foundations of modern molecular biology and genetics. Watson later served as director and president of Cold Spring Harbor Laboratory and was involved in the early development of the Human Genome Project.
