Walter Elias Disney was an American business magnate, animator, cartoonist, producer, director, screenwriter, and entrepreneur. He founded Walt Disney Studios and created many famous cartoon characters such as Mickey Mouse. Some of Disney's most commercially successful early films included Snow White and the Seven Dwarfs, Cinderella, and Peter Pan. He opened Disneyland in 1955, which was immensely popular. Disney had both positive effects on children by promoting values like equality, bravery, and happy endings, but also some negative effects through racial stereotypes and unrealistic body standards.
