Theodore Bikel (born May 2, 1924) is an Austrian-born character actor and Jewish folk singer. He made his film debut in The African Queen and was nominated for an Academy award for his role in The Defiant Ones.
He played the Captain in the original Broadway cast of The Sound of Music, and also played Tevye in the original run (but not the original cast) of Fiddler On the Roof.
In 1962, while a folksinger in nightclubs in New York's Greenwich Village, he heard Bob Dylan give his premiere performance of "Blowin' In the Wind." Bikel then went to his scheduled performance at the nearby White Horse Tavern, and became the first singer besides Dylan to perform the song in public.
In the early 1990s, he made two appearances on Star Trek: The Next Generation, playing Sergei Rozhenko, a Russian-born retired petty officer on a Starfleet vessel, who had found Worf as a boy, and taken him home and raised him as his son.
