Physicist, b. 1890, d. 1971. Bragg was born in Australia and attended Adelaide University. Later, he went to England with his father, and attended Trinity College, Cambridge. From 1912 to 1914, they studied the use of x-rays in determining the structure of crystals (x-ray crystallography).

William Lawrence Bragg worked at Trinity College (from 1914 to 1915), as a technical advisor for a company in France (from 1915 to 1917) and Manchester University (from 1919 to 1937). He then became director of the National Physical Laboratory from 1937 to 1938 and the Cavendish Professor of Experimental Physics at Cambridge from 1938 to 1953.

Bragg's research interests included the use of x-rays to determine the structure of proteins. He was in charge of the lab where James Watson and Francis Crick discovered the structure of the DNA molecule.

Bragg was awarded the 1915 Nobel Prize in physics jointly with his father, Sir William Henry Bragg

"for their services in the analysis of crystal structure by means of X-rays"
