Jackson, Wilfred (1906-1988) - As one of Walt Disney's earliest animators, Wilfred Jackson, familiar with the metronome because his mother was a music teacher, suggested using that instrument to aid in the synchronization of sound to the action in "Steamboat Willie" in 1928. He later went on to direct cartoons and features (he was a sequence director on eleven of them, from "Snow White and the Seven Dwarfs" to "Lady and the Tramp"), and eventually do the same for animated episodes of the anthology television series.
