Wilfred Emmons Jackson (January 24, 1906 – August 7, 1988) was an American animator, musical arranger and director best known for his work with Walt Disney Productions.
He was soon promoted to an animator and was instrumental in developing the Mickey Mousing technique, which synchronized the music and action for Steamboat Willie (1928).
He was then made the director for the Mickey Mouse and Silly Symphonies cartoon series, of which he directed the Academy Award-winning short films: The Tortoise and the Hare (1935), The Country Cousin (1936), and The Old Mill (1937).
A year later, after recovering, Disney asked Jackson to produce and direct animated segments for the Disneyland series.
Through an acquaintance from a close friend, Jackson called Walt Disney at his Hyperion studio, asking to speak with him.
Disney agreed, and Jackson was assigned to help John Lott, a studio janitor, wash paint off the animation cels.
