He met Flaherty (a strong influence) in the U.S.; reviewing Flaherty’s ‘Moana’, he was the first in English to employ the term ‘documentary’. McLaren, Lye, Cavalcanti, Jennings, Auden, Lee, Britten all worked for his renowned G.P.O. Film Unit, McLaren following him to Canada. The emigrée Reiniger made some films for him. Eisenstein (another formative influence) attended the première of Grierson’s ‘Drifters’. He said art was not a mirror, but a hammer.
