Fresh from the Marquette University drama department, Charles Siebert continued his theatrical studies at the London Academy of Music and Dramatic Arts. Upon his graduation, Siebert and his wife had become so enchanted with England that he attempted to extend his visa by claiming that he'd gotten a job as a jazz-dancing teacher--a ruse that worked for a full year before he was found out. Following his professional debut in a Morristown, New Jersey production of Oedipus Rex, Siebert sought out work on Broadway, paying the rent by appearing in such TV daytime dramas as Search for Tomorrow and As the World Turns, and accepting roles in what Siebert would later describe as "The God Shows:" Sunday-morning religious anthologies like Lamp Unto My Feet, Look Up and Live and The Eternal Light. In the late 1960s, he bemusedly found himself the subject of media attention when he appeared in the play The Changing Room, which featured one of Broadway's first all-male nude scenes. Moving to Hollywood in 1976, Siebert quickly became a member in good standing of producer Norman Lear's talent pool, guesting on such series as All in the Family and Maude and appearing regularly as Mr. Davenport on One Day at a Time. While he has appeared in a number of films and had recurring roles on several weekly series, Charles Siebert is best known for his work as ivy-league doctor Stanley Riverside II on the TV medical drama Trapper John MD (1979-1986).
