Stephen Bosustow

Stephen Reginald Bosustow was a Canadian-born American film producer from 1943 until his retirement in 1979. He was one of the founders of United Productions of America (UPA) and produced nearly 600 cartoon and live-action shorts. He is chiefly remembered for producing a string of Mr. Magoo and Gerald McBoing-Boing cartoons in the 1950s, three of which earned Academy Awards. He is the only film producer in history who received all the Oscar nominations in one category (1956), guaranteeing him the winning Oscar. Magoo's Puddle Jumper was the eventual winner.
