Bragg, William Lawrence, Sir, 1890-1971

Sir William Lawrence Bragg (31 March 1890 – 1 July 1971) was a British physicist who shared the 1915 Nobel Prize in Physics with his father, William Henry Bragg, "for their services in the analysis of crystal structure by means of X-rays", an important step in the development of X-ray crystallography. As of 2025, Bragg is the youngest ever Nobel laureate in physics, or in any science category, having received the award at the age of 25. Bragg was the director of the Cavendish Laboratory, Cambridge, when James D. Watson and Francis Crick reported the discovery of the structure of DNA in February 1953.
