William Denby "Bill" Hanna (14 July 1910 - 22 March 2001) was an American animator, director, producer, voice actor, and cartoon artist.
During the 1930s, Hanna steadily gained skill and prominence while working on cartoons such as Captain and the Kids. In 1937, while working at Metro-Goldwyn-Mayer, Hanna met Joseph Barbera. The two men began a collaboration that was at first best known for producing Tom and Jerry. In 1957, they co-founded Hanna-Barbera, which became the most successful television animation studio in the business, producing programs such as The Flintstones, The Jetsons, Scooby-Doo, The Smurfs, and Yogi Bear.
