Mary Kay Bergman  Mary Kay Bergman (June 5, 1961 – November 11, 1999), initially credited as Shannen Cassidy, was an American voice actress and voice-over teacher. Bergman was the lead female voice actress on "South Park" from the show's 1997 debut until her death. Throughout her career, Bergman performed voice work for over 400 television commercials and voiced over 100 cartoon, film, and video game characters. Born in Los Angeles, she had an interest in fantasy and animation early in her life. She acted in plays during high school and also studied theater at University of California, Los Angeles (UCLA). After struggling to secure on-screen acting jobs, she began taking work as a voice-over actress. In 1989, she began voicing the Disney character Snow White. In the 1990s, she voiced Daphne Blake in three films from the "Scooby Doo" franchise. Bergman was married to voice actor Dino Andrade before her suicide in November 1999. Shortly after her death, Andrade established the Mary Kay Bergman Memorial Fund. Mary Kay Bergman was born on June 5, 1961, in Los Angeles. She was the only child of musicians David "Dave" Bergman and Patricia Paris "Pat" McGowan. She grew up around the corner from the home of Adriana Caselotti, the original voice of Snow White. Her parents performed as a singing duo at lounges and clubs in Reno and Las Vegas and in Los Angeles. They settled in Los Angeles after her mother became pregnant. Characterizing her mother's previous work inking and painting cels for Fleischer, Bergman said it was a mechanical task, but it piqued her mother's interest in animation that was shared with Bergman years later by watching Saturday morning cartoon series with her. Among Bergman's favorite series were "Jonny Quest", "The Flintstones", and "Wait Till Your Father Gets Home", which she considered a "precursor to "The Simpsons"." Bergman attended Le Conte Middle School and Hollywood High School, graduating in June 1978 with top academic honors. Following in the steps of one of her idols, Carol Burnett, Bergman attended University of California, Los Angeles (UCLA) and studied theater arts from 1978 until 1981. She was a classmate and friend of future "The Simpsons" voice actress Nancy Cartwright. Her parents were Jewish, but Bergman was non-practicing and converted to Roman Catholicism after exploring several Christian denominations; however, she still remained proud of her Jewish heritage.
