John James "Jimmy" MacDonald was a British-born American foley artist, voice actor, musician, conductor, and the original head of Walt Disney Productions' sound effects department. He was also the voice of Mickey Mouse from 1947 to 1976.
In addition to directing sounds for animated shorts as aurally complicated as Mickey's Trailer, MacDonald developed many original inventions and contraptions to achieve expressive sounds for characters, like Evinrude the dragonfly from The Rescuers, the bees in Winnie the Pooh and the Honey Tree, and Spike the bee who gets the best of Donald Duck in the 1950s cartoon shorts.
MacDonald also provided the voice for Jaq and Gus and Bruno the dog in Cinderella and Walt Disney's Mickey Mouse's Birthday Party, the Dormouse in Alice in Wonderland, Humphrey the Bear, and the Wolf in The Sword in the Stone.
In 1993, he was posthumously inducted as a Disney Legend.
