Clarence Bynold Farrar, SM (November 27, 1874 – June 3, 1970) was an influential psychiatrist, the first Director of the Toronto Psychiatric Hospital (succeeded in 1966 by the Clarke Institute), and editor of The American Journal of Psychiatry for 34 years.
As a chief psychiatrist for the Canadian Army, Captain Farrar researched psychiatric cases of soldiers with shell shock and published his findings with Charles Kirk Clarke.
Farrar worked at various times as an assistant physician and director of laboratories at Sheppard and Enoch Pratt Hospital, associate in psychiatry at the Johns Hopkins Medical School, assistant physician at Trenton State Hospital, lecturer in abnormal psychology at Princeton University, head of Homewood Sanitarium in Guelph, medical director of Toronto Psychiatric Hospital and the head of the department of psychiatry at the University of Toronto.
Farrar's contributions to the field of psychiatry were recognized through honorary doctorates from McGill University and the University of Toronto, the Medal of Service of the Order of Canada from the Governor General of Canada, and the Distinguished Service Award of the Thomas W. Salmon Committee on Psychiatry and Mental Hygiene of the New York Academy of Medicine.
Farrar wrote there was no evidence for the claims of Spiritualism and that mediumship phenomena could be explained by delusion, fantasy and fraud.
