Jack Pennick was an American film actor, a familiar face, primarily in the movies of John Ford. He was born in Portland, Oregon, the son of gold miner Albert R. and Bessie (Murray) Pennick. After himself working as a gold miner, Pennick joined the U.S. Marine Corps and served, with the Pekin Legation Guard, in China in 1912 and in World War I. He and his first wife, Grechin, had two children by the time he was 20. He had a third child with his second wife, Nona Lorraine. After the First World War, Pennick worked as a horse wrangler and got work as such in various film productions. His rather unforgettably unattractive face caught the attention of filmmakers, particularly Ford, and Pennick began to get work as an actor, as well as occasionally a military technical adviser. Pennick re-enlisted in the navy in 1942, at the age of 46. He served as Chief Petty Officer under Commander John Ford in the Field Photographic Unit and, according to Ford, was decorated with the Silver Star medal for action in which he was wounded at Majaz al Bab, Tunisia during World War II. He continued to appear in films after the war, his career waning simultaneously with Ford's. He died in Manhattan Beach, California, at the age of 68.
