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".
The Magic Kingdom: Walt Disney and the American Way of Life
Walt Disney was born in Chicago on December 5, 1901 and lived in Marceline, Missouri from 1905 to 1910. When he was young, he had a talent for drawing and he earned money doing illustrations for newspapers and advertisements. He left home in 1919 and worked at a commercial art studio in Kansas City, after he was fired from the studio, he started his own shop in 1920. Soon, Walt worked at the Kansas City Film Ad Co. which was his first direct employment in animation. In 1922, he started Laugh-O-Gram Films until he went bankrupt. In 1923, he went to Hollywood and started a Los Angeles studio called Disney.
And on that train ride from Manhattan to Los Angeles, Mickey Mouse was born.
