Fun and Fancy Free
Disney had provided the voice for Mickey Mouse since his debut in 1928, and "Fun and Fancy Free" was the last time he would voice the role regularly, as he no longer had the time or energy to do so. Disney recorded most of Mickey's dialogue in the spring and summer of 1941. Sound effects artist Jimmy MacDonald would become the character's new voice actor, starting in 1948. Disney, however, did reprise the role for the introduction to the original 1955–59 run of "The Mickey Mouse Club".
Walt Disney
Born in Chicago in 1901, Disney developed an early interest in drawing. He took art classes as a boy and got a job as a commercial illustrator at the age of 18. He moved to California in the early 1920s and set up the Disney Brothers Studio with his brother Roy. With Ub Iwerks, Walt developed the character Mickey Mouse in 1928, his first highly popular success; he also provided the voice for his creation in the early years. As the studio grew, Disney became more adventurous, introducing synchronized sound, full-color three-strip Technicolor, feature-length cartoons and technical developments in cameras. The results, seen in features such as "Snow White and the Seven Dwarfs" (1937), "Pinocchio", "Fantasia" (both 1940), "Dumbo" (1941), and "Bambi" (1942), furthered the development of animated film. New animated and live-action films followed after World War II, including the critically successful "Cinderella" (1950) and "Mary Poppins" (1964), the latter of which received five Academy Awards.
