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".
Floyd Gottfredson
Walt Disney Productions hired Gottfredson as an apprentice animator and in-betweener on December 19, 1929. In April 1930 he started working on the four-month-old "Mickey Mouse" daily comic strip. It had originally been scripted by Walt Disney and drawn by Ub Iwerks who was succeeded by Win Smith (cartoonist). Iwerks later tried to hire Gottfredson at his studio after the former had left Disney, but Roy Disney refused to allow Gottfredson out of his contract. In May, Win Smith refused to write the strip, and Disney assigned Gottfredson to it, promising it would be only a temporary arrangement until someone else could be found to take over. Gottfredson continued to produce the "Mickey Mouse" strips for the next 45 years.
