Born in Odessa, Ukraine Leon Belasco was prepared for a musical career at various seats of learning in Japan and Manchuria. For several years, Belasco was first violinist for the Tokyo Symphony, and later led his own orchestra. Though he made his first film in 1926, his Hollywood career proper didn't begin until 1939. Together with Leonid Kinsky and Mischa Auer, Belasco was one of filmdom's favorite comic Russians, usually cast as an excitable musician, choreographer or aesthete. He also registered well in sinister roles, especially in World War II and Cold War espionagers. On radio, Leon Belasco was heard as larcenous informant Pagan Zeldschmidt on The Man Called X; his best-known TV role was Appopoplous the landlord in My Sister Eileen (1960).
