Research professor, Queen's University
After graduating from Melbourne U in 1907, he worked in Rutherford's lab in Manchester, England, studying the interaction of electrons and X rays with atoms. From 1924 until retiring in 1954 he was research professor at Queen's. His discoveries regarding the breadth of the energy spectrum of electrons and the scattering of X rays were important contributions to the development of the new theory of the atom. His work foreshadowed the Compton effect. He received the first Gold Medal of the Can. Assn. of Physicists in 1956.
In 1912 he went to McGill, and after WW I returned there. During the war he located enemy batteries by sound ranging, and was awarded an OBE. Research prof., Queen's U., 1924-54. The Royal Society of London, to which he was appointed in 1932, credited his work as "clearly foreshadowing what is known as the Compton effect" (for which A.H. Compton received the Nobel Prize). RSC, 1922.
