Sir William Henry Bragg (2 July 1862 – 12 March 1942) was a British X-ray crystallographer who uniquely shared a Nobel Prize with his son Lawrence Bragg – the 1915 Nobel Prize in Physics "for their services in the analysis of crystal structure by means of X-rays," an important step in the development of X-ray crystallography.
