John Grierson (26 April 1898 – 19 February 1972) was a Scottish documentary maker, often considered the father of British and Canadian documentary film. In 1926, Grierson coined the term "documentary" in a review of Robert J. Flaherty's Moana. In 1939, Grierson established the all-time Canadian film institutional production and distribution company The National Film Board of Canada controlled by the Government of Canada.
