Onslow Stevens was an American stage, television and film actor.
Born Onslow Ford Stevenson in Los Angeles, California, he was the son of character actor Housley Stevenson. Stevens became involved in performing in 1928, appearing in Under the Roof at the Pasadena Community Playhouse, where his entire family worked as performers, directors and teachers. His first major success came from his performance in the Broadway play Stage Door. He then went on to star in over 80 films, at first as the lead actor, but mostly in character roles later in his career.
He spent the last years of his life in a nursing home in Van Nuys, Los Angeles, California, where, according to his wife, he was abused by his fellow patients. He died of pneumonia after suffering a broken hip in 1977, at the age of 74. His interment was located in Valhalla Memorial Park Cemetery with an unmarked grave.
