Les Tremayne (1913-2003), though born in England, had moved with his family to Chicago at the age of four. Early on, he worked as an amusement park barker as well as in vaudeville. In the 1930s, he moved on to radio, the medium he's most associated with. Among his roles there are as Nick Charles in The Adventures of the Thin Man and the title character on The Falcon. By the 1950s, he had moved on to film and television, where he was often cast as shifty executives, errant husbands, and authoritative, no-nonsense professionals. In the latter stages of his career, he performed voice work in TV animation.
