William Henry Bragg married Gwendoline Todd in 1889. The couple had two sons, named William Lawrence and Robert, and a daughter named Gwendolen.
He died on March 10, 1942 in London, England, at the age of 79. The reasons behind his death are unknown.
William Henry Bragg was born on July 2, 1862 in Wigton, England, to Robert John Bragg and his wife Mary Wood. His father was a farmer and also worked as a merchant marine officer.
His mother passed away when he was only seven years old and his uncle, also named William Bragg, took the responsibility of raising him. He moved to Market Harborough, Leicestershire, to live with his uncle. He studied at the Old Grammar School in Market Harborough and then at the King William’s College located in the Isle of Man.
After graduating from high school, he won a scholarship from Trinity College, Cambridge University and started studying there in 1881. He studied mathematics under the tutorship of Dr. E. J. Routh and graduated in 1884 as third wrangler, and was awarded a first class honours in the mathematical tripos in 1885.
Following his graduation from University of Cambridge, the University of Adelaide in Australia appointed him as the Elder Professor of Mathematics and Experimental Physics in 1885. He took up the position the following year.
Gradually his interest in physics developed, particularly in the field of electromagnetism. He was greatly interested in new discovery of Wilhelm Röntgen, namely X-Rays. His friendship with Ernest Rutherford further developed his interest in the field.
In 1896, at a gathering of doctors, William Henry Bragg demonstrated that X-rays could be used to reveal structures that were otherwise invisible.
In 1904, he delivered an address in Dunedin, New Zealand for the Australian Association for the Advancement of Science on the theory of ionization of gases and his research on the subject bore fruit when his efforts led to a fellowship from the Royal Society of London. In the same year, he also published papers in relation to Alpha Rays and Ionization Curves of Radium.
During his time in Australia, he was also active in sports. He played golf, lawn tennis, lacrosse and chess. He helped establish the Adelaide University Lacrosse Club as well as the North Adelaide Lacrosse Club.
He along with his son, William Lawrence Bragg, invented the X-ray spectrometer, and the studies of the father-son duo led to the analysis of crystal structure by means of X-rays.
