Bill Peet (born William Bartlett Peed; January 29, 1915 – May 11, 2002), was an American children's book illustrator and a story writer for Disney Studios. He joined Disney in 1937 and worked first on Snow White and the Seven Dwarfs (1937) near the end of its production. Progressively, his involvement in the Disney studio's animated feature films and shorts increased, and he remained there until early in the development of The Jungle Book (1967). A row with Disney over the direction of the project led to a permanent personal break. Other feature films that Peet worked on before he left include Pinocchio (1940), Fantasia (1940, The Pastoral Symphony sequence), Dumbo (1941), The Three Caballeros (1944), Song of the South (1946, cartoon sequences), So Dear to My Heart (1948, cartoon sequences), Cinderella (1950), Alice in Wonderland (1951), Peter Pan (1953), Sleeping Beauty (1959), 101 Dalmatians (1961), and The Sword in the Stone (1963). Peet's subsequent career was as a writer and illustrator of children's books.
