Debut of Mickey Mouse

November 18, 1928, was the debut of Mickey Mouse. Walt Disney was quoted as saying, “I only hope that we never lose sight of one thing—that it was all started by a mouse.” He was talking, of course, about Mickey Mouse, who made his debut in Disney’s first sound-synchronized animated film, Steamboat Willie. Disney’s impact on generations of children is impossible to measure, and his career started in Missouri.
