Alvin and the Chipmunks is a six-time Grammy Award-winning animated music group created by Ross Bagdasarian, Sr. in 1958. The group consists of three singing animated chipmunks: Alvin, the mischievous troublemaker, who quickly became the star of the group; Simon, the tall, bespectacled intellectual; and Theodore, the chubby, impressionable sweetheart. The trio is managed by their human father and confidant, David Seville. In reality, David Seville was Bagdasarian's stage name, and the Chipmunks themselves are named after the executives of their original record label, Liberty Records: Alvin Bennett (the president), Simon Waronker (the founder and owner), and Theodore Keep (the chief engineer).   Wikipedia
