Otto Kruger was of German descent. He was the grandnephew of South African pioneer and president Paul Kruger. Otto was musically trained, but switched careers and became an actor. He studied briefly at Columbia University. Making his Broadway debut at the age of fifteen, Kruger quickly became a matinee idol. Though he started to get noticed in the early 1920s, it was the 1930s when his career was at its height, including an appearance in the film Chained (1934) with Joan Crawford and Clark Gable. Though he played the hero on occasion, for most of his career, he played the main villain or a charming or corrupt businessman. One of his best known roles was in the Douglas Sirk film Magnificent Obsession (1954). Kruger played the supporting role of Judge Percy Mettrick, who unsuccessfully urges Will Kane to leave town in High Noon (1952). Kruger is also remembered for playing the villain Tobin in Alfred Hitchcock’s film Saboteur (1942). His television roles included those of Dr. Mumford in the 1959 episode “Experiments in Terror” of the NBC science fiction/adventure series The Man and the Challenge, as Ben Tully in “Gun City” of the ABC western series, The Rebel, and as Franklyn Malleson Ghentin in the 1961 episode “A Fool for a Client” of James Whitmore ABC’s legal drama, The Law and Mr. Jones. Kruger made four guest appearances on CBS’s Perry Mason. In his first two appearances, “The Case of the Grumbling Grandfather” in 1961, and “The Case of the Counterfeit Crank” in 1962, he was cast as Mason’s client, and in both episodes was the title character. In his final appearance in 1964, he played Judge Norris in “The Case of the Missing Button.” On March 20, 1920, Kruger secretly married Broadway actress Susan “Sue” MacManamy (1892–1976). Their daughter, Ottilie (1926–2005), was also an actress and was the first wife of pioneering cinematographer Gayne Rescher. Kruger died at the Motion Picture and Television Country House in Woodland Hills, California, on his 89th birthday.
