James Watson
An American molecular biologist who co-discovered the structure of DNA, one of the most significant scientific discoveries of the 20th century
Working alongside a British colleague to crack one of biology's greatest remaining mysteries, this scientist's discovery of DNA's structure fundamentally transformed the entire field of genetics.
Co-Discovering DNA's Structure
Watson, along with colleague Francis Crick, co-discovered the double helix structure of DNA in 1953, one of the most significant scientific discoveries of the 20th century.
A Nobel Prize in Physiology or Medicine
Watson received the Nobel Prize in 1962, shared with Crick and researcher Maurice Wilkins, for the DNA structure discovery.
Building on Rosalind Franklin's Work
Watson and Crick's discovery relied significantly on X-ray crystallography data produced by researcher Rosalind Franklin, whose contribution was not fully recognized during her lifetime.
Transforming Modern Genetics
The discovery of DNA's structure fundamentally transformed modern genetics, enabling subsequent advances including genetic engineering and the Human Genome Project.
