Rudolph Anders (December 17, 1902 in Germany – March 27, 1987 in Woodland Hills, Los Angeles, California, USA) was a German character actor who came to the United States after the rise of Hitler, and appeared in numerous American films in the 1940s, 1950s and 1960s. During the 1940s, he used the stage name of Robert O. Davis. His German-accented English confined him largely to "accent roles", and during World War II to villain parts, although not leading roles as his small build, wide eyes, soft voice and naturally quiet demeanor did not allow him to appear overly menacing.
