Walt Disney, born in Chicago in 1901, worked as a commercial artist before setting up a small studio in Los Angeles to produce animated cartoons. In 1928, his short film Steamboat Willy, starring the character “Mickey Mouse,” was a national sensation. It was the first animated film to use sound, and Disney provided the voice for Mickey. From there on, Disney cartoons were in heavy demand, but the company struggled financially because of Disney’s insistence on ever-improving artistic and technical quality. His first feature-length cartoon, Snow White and the Seven Dwarfs (1938), took three years to complete and was a great commercial success.
