He turned X-rays into a way to see the architecture of molecules — a technique that unlocked the structure of life itself and made modern molecular biology possible.

Biography

About

John Desmond Bernal was born in Ireland on 10 May 1901. He pioneered X-ray crystallography in molecular biology, using the method to reveal molecular structures that had been invisible before. Beyond the lab, he published extensively on the history of science and wrote popular books exploring the relationship between science and society. He was a communist activist and a member of the Communist Party of Great Britain. Bernal died on 15 September 1971, leaving a method that would shape decades of discovery.
