Martin Kosleck (March 24, 1904 – January 15, 1994) was a German film actor. Like many other German actors, he fled when the Nazis came to power. Inspired by his deep hatred of Adolf Hitler and the Nazis, Kosleck would make a career in Hollywood playing villainous Nazis in films. While in the United States, he would appear in more than 80 films and television shows in a 46-year span. His icy demeanor and piercing stare on screen made him a popular choice to play Nazi villains.
