Lisa Marie Simpson is a fictional character in the animated television sitcom series The Simpsons. She is the middle child of the Simpson family. Voiced by Yeardley Smith, Lisa was born as a character in The Tracey Ullman Show short "Good Night" on April 19, 1987. Cartoonist Matt Groening created and designed her while waiting to meet James L. Brooks. Groening had been invited to pitch a series of shorts based on his comic Life in Hell, but instead decided to create a new set of characters. He named the older Simpson daughter after his younger sister Lisa Groening Bartlett. After appearing on The Tracey Ullman Show for three years, the Simpson family were moved to their own series on Fox, which debuted on December 17, 1989.
Intelligent, kind, and passionate about the planet and all living things, Lisa Simpson is the second child of Homer and Marge. Born Mother's Day, May 9, 1981, she is the younger sister of Bart, and the older sister of Maggie, at age 8. Lisa's high intellect and left-wing political stance creates a barrier between her and other children her age; therefore she is a bit of a loner and social outcast with few friends. Lisa is a vegetarian, a strong environmentalist, a feminist, and a Buddhist. Lisa's character develops many times over the course of the show: most notably, she becomes a vegetarian in season 7 and converts to Buddhism in season 13. A strong liberal and activist for peace, equality, and the environment, Lisa advocates for a variety of political causes (e.g. standing against apartheid in South Africa and supporting the Tibetan independence movement) which sets her against most of the people in Springfield. However, she can also be somewhat intolerant of opinions that differ from her own, often refusing to consider alternative perspectives and showing a feeling of self-righteousness. In her free time, Lisa enjoys many hobbies such as reading and playing the baritone saxophone and guitar. She has appeared in other media relating to The Simpsons – including video games, The Simpsons Movie, The Simpsons Ride, commercials and comic books – and inspired a line of merchandise.
Yeardley Smith originally tried out for the role of Bart, while Nancy Cartwright (who was later cast as the voice for Bart) tried out for Lisa. Producers considered Smith's voice too high for a boy, so she was given the role of Lisa. In the Tracey Ullman Show shorts, Lisa was something of a "female Bart" who mirrored her brother's mischief, but as the series progressed she became a liberal voice of reason which has drawn both praise and criticism from fans of the show. Because of her unusual pointed hairstyle, many animators consider Lisa the most difficult Simpsons character to draw.
Originally conceived and described as simply the "middle child", without much other personality shown in her earliest appearances, Lisa has since undergone significant character expansion to the point where she is now commonly considered by critics, scholars and many fans to be one of the best-developed and most enduring female characters in television history. TV Guide ranked her 11th (tied with Bart) on their list of the "Top 50 Greatest Cartoon Characters of All Time". Her environmentalism has been especially well-received; several episodes featuring her have won Genesis and Environmental Media Awards, including a special "board of directors Ongoing Commitment Award" in 2001. People for the Ethical Treatment of Animals (PETA) included Lisa on their list of the "Most Animal-Friendly TV Characters of All Time". Yeardley Smith won a Primetime Emmy Award for Outstanding Voice-Over Performance in 1992, and Lisa and her family were awarded a star on the Hollywood Walk of Fame in 2000.
