Austrian zither player and composer was born on this day in 1906. In the summer of 1948, director (Mr.) Carol Reed went to a nightclub in Vienna, heard Karas play, and asked if he would write the score for the film The Third Man. They sent Karas to England to compose, but after a while he was homesick and asked to go home. Reed said he could after the score was complete. "The Third Man Theme," also called "The Harry Lime Theme," sold half a million copies by 1949 and helped to make the movie and Karas a success. In this video, Karas is playing his own composition.
