According to Wikipedia: "Joseph Roland Barbera was an American animator, director, producer, storyboard artist, and cartoon artist, whose film and television cartoon characters entertained millions of fans worldwide for much of the 20th century. He was born to Italian immigrants in New York City, where he lived, attended college and began his career through his young adult years. After working odd jobs and as a banker, Barbera joined Van Beuren Studios in 1927 and subsequently Terrytoons in 1929. In 1930, he moved to California and while working at Metro-Goldwyn-Mayer (MGM), Barbera met William Hanna. The two men began a collaboration that was at first best known for producing Tom and Jerry. In 1957, after MGM dissolved their animation department, they co-founded Hanna-Barbera, which became the most successful television animation studio in the business, producing programs such as The Flintstones, Yogi Bear, Scooby-Doo, Top Cat, The Smurfs, Huckleberry Hound, and The Jetsons. In 1967, Hanna-Barbera was sold to Taft Broadcasting for $12 million, but Hanna and Barbera remained heads of the company. In 1991, the studio was sold to Turner Broadcasting System, which in turn was merged with Time Warner, owners of Warner Bros., in 1996; Hanna and Barbera stayed on as advisors."
