Alvin and the Chipmunks is a five-time Grammy Award-winning animated music group, created by Ross Bagdasarian, Sr. in 1958. The group consists of three singing 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.
