Actor Charles Trowbridge was born in Mexico to American parents. An architect for the first decade of his adult life, Trowbridge turned to stage acting in the early teens, making his film bow in 1918's Thais. Silver-haired even as a young man, Trowbridge was generally cast in kindly but authoritative roles, usually as doctors, lawyers and military officers. He also had a bad habit of being killed off before the film was half over; in 1940, Trowbridge had the distinction of being murdered (by Lionel Atwill and George Zucco respectively) in two separate Universal horror films, Man Made Monster and The Mummy's Hand. While he was active until 1957, Charles Trowbridge was best known to millions of wartime servicemen as the cautionary military doctor in John Ford's venereal disease prevention film Sex Hygiene (1941).
