After a brief stint as a junior faculty member at the University of Toronto, he returned to Princeton, where he was a professor in the Department of Physics 1925–62.
Joseph Shenstone was a senior executive of the Massey-Harris Company,[1] a large manufacturer of agricultural equipment that later became Massey Ferguson.
Shenstone attended Huron Street Public School and Harbord Collegiate Institute in Toronto.
[3] He graduated magna cum laude in 1914 and then spent two terms at the Cavendish Laboratory of the University of Cambridge working on experiments under J. J. Thomson and C. T. R.
He saw action at Passchendaele and the Hindenburg Line, was promoted to captain in September 1917,[1] and received the Military Cross.
Shenstone struggled initially with returning to research after five years at war but was nonetheless awarded a prestigious fellowship.
This time he worked under Ernest Rutherford on experiments related to radioactivity and earned a second Bachelor of Arts from Cambridge.
He completed his Ph.D. at Princeton the following year, writing his dissertation on an experiment that attempted to show a connection between the Hall effect and photoemission.
At Princeton he secured new research equipment and performed important experiments, establishing himself as a leader in optical spectroscopy.
In November 1940 he moved to Ottawa, where he served as Special Assistant to the President of the Canadian National Research Council.
