Harry Allen was an Australian-born American character actor of the silent and sound film eras. He was born in Melbourne, Victoria, Australia. Allen's World War One registration card gives his date of birth as 10 July, 1876 and confirms his place of birth as Melbourne, although at least one obituary gives the later birth year of 1883.
