Jimmy MacDonald

John James MacDonald (May 19, 1906 – February 1, 1991) was a British-born American animator, voice actor, musician, and the original head of the Disney sound effects department. He was also the voice of Mickey Mouse from 1948 to 1977.

Career and sound effects
In addition to directing sounds for animated shorts as aurally complicated as Mickey's Trailer (1938), he developed many original inventions and contraptions to achieve expressive sounds for characters like Casey Jr., the circus train engine from Dumbo (1941); Evinrude the dragonfly from The Rescuers (1977); the bees in Winnie the Pooh and the Honey Tree (1966); and Buzz-buzz (later called "Spike"), the bee who gets the best of Donald Duck in his 1950s short films. He also made the sound effects of Tick Tock the crocodile from Peter Pan (1953) and Dragon Maleficent from Sleeping Beauty (1959) by using castanets.

MacDonald also added voice effects, like on-screen humming for Kirk Douglas in 20,000 Leagues Under the Sea (1954).

Almost all of his effects were available on Cartoon Trax Volume 1 in 1992.

By the time of his death, he was preparing to work on the sounds for the Splash Mountain attraction in Tokyo and Walt Disney World.
