Categories: Physicists

1862 – Born on July 2nd in Wigton, Cumberland, England. British scientist in solid-state physics who was a joint winner of the Nobel Prize for Physics.

1875 – He was sent to school at King William College, Isle of Man.

1882 – He was granted a scholarship at Trinity College, Cambridge.

1884 – He obtained third place in the Mathematical Tripos (final examinations), a splendid achievement.

1885 – He was appointed as professor of mathematics and physics at the young University of Adelaide.

1904 – Bragg became president of the physics section of the Australian Association for the Advancement of Science, that he began to think about original research.

1907 – He was elected to the fellowship of the Royal Society and within a year was offered a professorship in Leeds, England, where he developed his view that both gamma rays and X rays have particle-like properties.

1912 – He designed the Bragg ionization spectrometer, the prototype of all modern X-ray and neutron diffractometers, with which he made the first exact measurements of X-ray wavelengths and crystal data.

1915 – Joint winner (with his son Sir Lawrence Bragg) of the Nobel Prize for Physics for his research on the determination of crystal structures.

         – Bragg and his elder son, Lawrence, who was studying physics at Cambridge, then began to apply X rays to the study of crystal structure.

1920 – He was knighted.

1934-1940 – He was president of the Royal Society and received many other honours, but, to the last, he remained simple, gentle, and humble about his own success and proud of his son’s.
