Susan Oliver (February 13, 1932 – May 10, 1990), stage name of Charlotte Gercke, was an Emmy-nominated American actress, television director and aviator.
Susan Oliver was born Charlotte Gercke, the daughter of journalist George Gercke and astrology practitioner Ruth Hale Oliver, in New York City in 1932. Her parents divorced when she was still a child. In June 1949, Oliver joined her mother in Southern California, where Ruth Hale Oliver was in the process of becoming a well-known Hollywood astrologer. Oliver made a decision to embark upon a career as an actress and chose the stage name Susan Oliver.
By September 1949, using her new name, Oliver returned to the East Coast to begin drama studies at Swarthmore College, followed by professional training at the Neighborhood Playhouse in New York City. After working in summer stock, regional theater and in unbilled bits in daytime and primetime TV shows and commercials, she made her first major television appearance playing a supporting role in the July 31, 1955 episode of the live drama series Goodyear TV Playhouse, and quickly progressed to leading parts in other shows.
