Setting the scene
Walter Elias Disney was born on December 5, 1901, in Chicago, Illinois, and grew up in Marceline, Missouri, and Kansas City. He drew for a neighborhood paper and drove an ambulance in France after World War I before animating in Kansas City.
What happened
He co-founded Disney Brothers Studio with brother Roy, created Mickey Mouse in Steamboat Willie (1928), and released Snow White and the Seven Dwarfs (1937), the first full-length animated feature. Disneyland opened in Anaheim in 1955.
Why it still matters
Disney won 26 Academy Awards and built a media empire continued after his 1966 death. Memorable detail: Disney took out multiple mortgages on his house to finish Snow White; skeptics called it 'Disney's Folly' until it earned roughly $8 million in its initial run.
Background
Snow White and Disneyland followed.
