Sir William Lawrence Bragg (31 March 1890 – 1 July 1971) was an Australian-born 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",[3] an important step in the development of X-ray crystallography.[4]
As of 2024, he is the youngest ever Nobel laureate in physics, or in any science category, having received the award at the age of 25.[5] Bragg was the director of the Cavendish Laboratory, Cambridge, when the discovery of the structure of DNA was reported by James D. Watson and Francis Crick in February 1953.
