Actress Nancy Cartwright is best known for a role for which she never appeared on camera. As Bart Simpson on the Fox animated comedy "The Simpsons" (1990- ) and before that in shorts on "The Tracey Ullman Show" (Fox, 1987-90), her work was well known, although as a voice actor she was largely unrecognized in person. From childhood, Cartwright realized she had unusual vocal talents, and after a job at an Ohio radio station afforded her an opportunity to use her skills and get them noticed, it was advised that she get involved in animation. One of the contacts recommended to her was the legendary voice actor Daws Butler, who had brought life to Elroy Jetson, among other classic cartoon characters. Her ambition putting her into immediate action, Cartwright called Butler, and transferred to UCLA to be closer to his Beverly Hills home, where she was trained by him in vocal technique. Together they produced her demo reel, which got her work on the ABC Saturday morning animated series "The Richie Rich Show" (1980-82), voicing Richie's girlfriend Gloria. From there, many other animated voices would follow, with roles on several series including "Snorks" (NBC, 1984-86), "Galaxy High School" (CBS, 1986-88) and Pound Puppies (ABC 1986). Her voice could also be heard in the animated features "My Little Pony" (1986), "The Chipmunk Adventure" (1987), "Little Nemo: Adventures in Slumberland" (1990) and Disney's "The Little Mermaid" (1989).
