1909 – He went to England to enter Trinity College, Cambridge.
1912 – He was the discoverer of the Bragg law of X-ray diffraction, which is basic for the determination of crystal structure.
1914 – Bragg became a fellow and lecturer in natural sciences at Trinity College.
– He and his father were jointly awarded the Barnard Gold Medal of the U.S. Academy of Sciences, the first of many such honours and awards.
1915 – He was joint winner (with his father, Sir William Bragg) of the Nobel Prize for Physics.

– He was in France when the Nobel Prize for Physics was awarded jointly to his father and himself for demonstrating the use of X rays for revealing the structure of crystals.
1921 – He married Alice Hopkinson, a doctor’s daughter, by whom he had two sons and two daughters.
– He was elected a Fellow of the Royal Society.
1937 – Bragg was director of the National Physical Laboratory, but he was impatient with committee work.
