Cuban-born bandleader of the 30s/40s, who co-starred in and produced I Love Lucy. His thick accent, along with such things as Lucy's "red" hair and thwarted showbiz ambitions, was a running motif in the show's run. At Desilu, he had a hand in several hit TV shows of the 50s/60s, like The Untouchables, The Andy Griffith Show (he "owned" Mayberry), The Mothers-in-Law (in which he made a very brief return to acting), and The Dick Van Dyke Show.
