Background: Robert Emerson Clampett was born in San Diego, California on May 8, 1913. Clampett was displaying extraordinary art skills by the age of five. From the beginning, Clampett was intrigued with and influenced by Douglas Fairbanks, Lon Chaney, Charlie Chaplin, Buster Keaton and Harold Lloyd, and he began making film short-subjects in his garage beginning when he was twelve. While living in Hollywood as a young boy, Clampett and his mother Joan lived next door to Charlie Chaplin and his brother Syd.
Context: In 1946 after Warner Bros. bought out Leon Schlesinger, his key executives Henry Binder and Ray Katz went to Screen Gems and took Clampett with them. Clampett worked for a time at Screen Gems, then the cartoon division of Columbia Pictures, as a screenwriter and gag writer. In 1947 Republic Pictures incorporated animation (by Walter Lantz) into its Gene Autry feature film Sioux City Sue. It turned out well enough for Republic to dabble in animated cartoons; Bob Clampett directed a single cartoon, It's a Grand Old Nag, featuring the equine character Charlie Horse. Republic management, however, had second thoughts due to dwindling profits, and discontinued the series. Clampett took his direction credit under the name "Kilroy". In 1949, Clampett turned his attentions to television, where he created the famous puppet show Time for Beany. The show, featuring the talents of voice artists Stan Freberg and Daws Butler, would earn Clampett three Emmys. Groucho Marx and Albert Einstein were both fans of the series. In 1952, he created the Thunderbolt the Wondercolt television series and the 3D prologue to Bwana Devil featuring Beany and Cecil. In 1954, he directed Willy the Wolf (the first puppet variety show on television), as well as creating and voicing the lead in the Buffalo Billy television show. In the late 1950s, Clampett was hired by Associated Artists Productions to catalog the pre-August 1948 Warner cartoons it had just acquired. He also created an animated version of the puppet show called Beany and Cecil, whose 26 half-hour episodes were first broadcast on ABC in 1962 and were rerun on the network for five years. In his later years, Bob Clampett toured college campuses and animation festivals as a lecturer on the history of animation. In 1975 he was the focus of a documentary entitled Bugs Bunny: Superstar, the first documentary to examine the history of the Warner Bros. cartoons. Clampett, whose collection of drawings, films, and memorabilia from the golden days of Termite Terrace was legendary, provided nearly all of the behind-the-scenes drawings and home-movie footage for the film; furthermore, his wife, Sody Clampett, is credited as the film's production co-ordinator. In an audio commentary recorded for Bugs Bunny: Superstar, director Larry Jackson claimed that in order to secure Clampett's participation, and access to Clampett's collection of Warners history, he had to sign a contract that stipulated Clampett would host the documentary and also have approval over the final cut. Jackson also claimed that Clampett was very reluctant speaking about the other directors and their contributions. Clampett died of a heart attack on May 2, 1984 in Detroit, Michigan, six days before his 71st birthday, while touring the country to promote the home video release of Beany & Cecil cartoons. He is buried in Forest Lawn Hollywood Hills. CANNOTANSWER
