A bit of background

Ross Bagdasarian Sr. came up with the Chipmunks after experimenting with sped‑up vocal recordings that he had first used on his novelty hit “Witch Doctor.” Building on that sound, he created “The Chipmunk Song (Christmas Don’t Be Late)” in 1958, introducing Alvin, Simon, and Theodore as a fictional singing trio managed by his human persona, David Seville.

The characters quickly expanded beyond that single song into albums, TV shows, and later films, turning into a long‑running entertainment franchise handled after his death by his son Ross Bagdasarian Jr. and daughter‑in‑law Janice Karman.

TL;DR: Ross Bagdasarian Sr. (David Seville) created Alvin and the Chipmunks in 1958 as a sped‑up vocal novelty act that grew into the famous animated chipmunk trio seen in TV and movies today.
