George Brock Chisholm, CC, CBE, psychiatrist, medical administrator, soldier (born 18 May 1896 in Oakville, ON; died 4 February 1971 in Victoria, BC). After earning honours for courageous service in the First World War, Brock Chisholm became an influential psychiatrist. He introduced mental health as a component of the recruitment and management of the Canadian Army during the Second World War. He directed the army’s medical services, served in the federal government as deputy minister of health, and became the founding director-general of the World Health Organization (WHO). His vocal attacks on methods of indoctrinating children with societal myths made him a controversial public figure. He was an often provocative advocate of world peace and mental health.
