Bill Melendez, the Emmy Award-winning animator of more than 70 cartoons featuring characters from the Peanuts comic strip, has died aged 91 at a hospital in Santa Monica, California.

Melendez died on Tuesday, according to a statement on his website. The cause of death was not reported.

Melendez's most famous work was A Charlie Brown Christmas, a half- hour special produced in 1965 that is still replayed every year on US network television. The show represented Melendez's first attempts at animating cartoonist Charles M Schulz's popular characters. Sponsored Links:

Under the pressure of a tight deadline he even voiced the beloved character of Snoopy. He went on to serve as Snoopy's voice in 63 subsequent half-hour specials, five one-hour specials, the Saturday morning TV show and four feature films.

Melendez also animated more than 370 commercials using Peanuts characters and remains the only animator Schulz trusted to bring his famous comic strip figures to life. Sponsored Links:

Prior to working on Peanuts, Melendez drew many of the famous Disney and Warner Bros animated figures of the 1930s and 1940s, including Mickey Mouse, Donald Duck, Bugs Bunny and Porky Pig, and worked on the film classics Pinocchio, Fantasia, Bambi and Dumbo.

Melendez won five Emmy Awards for his work on Peanuts. He also won Emmys for creating the first animated cartoons of Jim Davis' Garfield and for animating CS Lewis' The Lion, the Witch and the Wardrobe. Sponsored Links:
