Alvin and the Chipmunks were originally David Seville and the Chipmunks or simply the Chipmunks. They are an American animated music group created by Ross Bagdasarian Sr. for a novelty record in 1958. The group consists of three singing animated anthropomorphic chipmunks: Alvin, the mischievous troublemaker, who quickly became the star of the group; Simon, the tall, bespectacled intellectual; and Theodore, the chubby, impressionable one. The trio is managed by their human mentor and later adoptive father David (Dave) Seville. In reality, "David Seville" was Bagdasarian's stage name, and the Chipmunks themselves are named after the executives of their original record label. The characters became a success, and the singing Chipmunks and their manager were given life in several animated cartoon productions and eventually films, using redrawn, anthropomorphic chipmunks.
The voices of the group were all performed by Bagdasarian, who sped up the playback to make them high pitched. This oft-used process was not entirely new to Bagdasarian, who had also used it for two previous novelty songs, including "Witch Doctor", but it was so unusual and well-executed that it earned the record two Grammy Awards for engineering. Bagdasarian performed as the Chipmunks to release a long line of albums and singles, with "The Chipmunk Song" becoming a number-one single in the United States. After his death in 1972, the characters' voices were performed by his son Ross Bagdasarian, Jr. and the latter's wife Janice Karman in the subsequent incarnations of the 1980s and 1990s.
The characters were voiced in dialogue by Justin Long, Matthew Gray Gubler, and Jesse McCartney in the 2007 CGI/live-action film adaptation and its 2009 sequel. Bagdasarian, Jr. and Karman continue to perform the singing voices for Alvin, Theodore, and the Chipettes, but Steve Vining does Simon's singing voice. The project has earned five Grammy awards, an American Music Award, a Golden Reel Award, and three Kids' Choice Awards; it has also been nominated for three Emmy awards and has pending for three Golden Raspberry Awards.
