Wilfred Jackson played an important role in synchronizing sound to the movements of animated characters. He got his start working on Disney Studios' early Mickey Mouse and Silly Symphony shorts in 1928. Jackson won Oscars during the '30s for his shorts the Tortoise and the Hare, Me Country Cousin, and The Old Mill. After that he worked as a sequence director on Disney's first animated features, including Snow White and the Seven Dwarves and Fantasia. In the late '50s, Jackson produced and directed episodes of the Disneyland television series.
