Born in Germany, Anders was billed under his given name of Rudolph Amendt when he made his American screen bow in Stamboul Quest (1934). He became "Robert O. Davis" for such roles as Franz Joseph in Champagne Waltz (1937) and "His Excellency" in the 1941 serial King of the Texas Rangers. During the war years, when character actors with Germanic names became bankable commodities, he settled upon "Rudolph Anders," and remained so until his retirement in 1964. Anders flourished in sinister roles, often playing Nazis or communist spies. In the early 1950s, he was seen as Teutonic scientists in the sci-fiers Phantom from Space (1953) and The Snow Creature (1954). And on TV, he played Dr. Von Meter on the kiddie serial Space Patrol. Rudolph Anders was back at work for Der Fatherland as a Nazi doctor in his final film, 36 Hours (1964).
