Walt Disney was an American animator, film producer, and businessman who was the founder of The Walt Disney Company. He created many famous animated films and characters from the Golden Age of Animation in the 1930s and 1940s, including Steamboat Willie, Silly Symphonies, and Snow White and the Seven Dwarfs. Snow White was groundbreaking as it was the first full-length animated feature film and pioneered the use of techniques like rotoscoping to make character movements more lifelike. Fantasia was also innovative for being the first film to use stereophonic sound. While Walt Disney passed away in 1966, The Princess and the Frog in 2009 was Disney's last traditionally drawn animated film.
