In 1916, Humphrey traveled to
Canada to teach classics at
St. Francis Xavier University until 1918. After receiving his doctorate in 1920, he took a job as an assistant professor for four years at Wesleyan University in the
United States. Humphrey returned to Canada and was given the position of Charlton Professor in Philosophy at Queen's University from 1924 to 1947. When he arrived at the university, psychology was a relatively new field of study and was included in the Department of Philosophy. He made great strides to further develop this aspect of the department. In 1939, he founded the Canadian Psychological Association and appointed Donald Hebb to be the first instructor in experimental psychology at Queen's. Like other experimental psychologists at the time, he set up his own laboratory to bring the study of experimental psychology to the university. He was named head of the department and added new psychology courses, including graduate courses. Because of Humphrey's contributions, the university began to recognize psychology as being independent from the philosophy department, but wasn't formalized until 1949 after he left. He went on to become the first professor of psychology at his alma mater, University of Oxford, which had just opened a new honors school in psychology, philosophy, and physiology. He prompted the university to establish the Oxford Institute of Experimental Psychology and was named its first director. Humphrey also helped to develop military personnel tests and directed research for the
Canadian Army during
World War II. In 1956, he retired to Cambridge, England at the age of 67. Though no longer a professor, he continued to give lectures in
Germany for the British Embassy. == Major contributions and works ==
