Mary Kay Bergman

Mary Kay Bergman (June 5, 1961 – November 11, 1999), also briefly credited as Shannen Cassidy, was an American voice actress and voice-over teacher. She was the official voice of the Disney character Snow White from 1989 to 1999 and the lead female voice actress on the adult animated television series South Park from the show's debut in 1997 until her death in 1999. In 1997, she was cast as nearly every female character in South Park after giving Trey Parker and Matt Stone ideas they originally did not have.

Her characters included Liane Cartman, Sheila Broflovski, Shelly Marsh, Sharon Marsh, Carol McCormick, and Wendy Testaburger. Although the show appealed to Bergman's "dark sense of humor", she was credited as Shannen Cassidy (taken from Shannen Doherty and David Cassidy) in the first two seasons due to the concerns that her voice role as Snow White would be taken out if the Walt Disney Company knew that she was in South Park. On November 11, 1999, Bergman wrote two suicide notes and shot herself in the head. Shortly after she died, her widower, Dino Andrade, established the Mary Kay Bergman Memorial Fund.
