Alison Margaret Arngrim (born January 18, 1962 in New York, New York) is an American actress and stand-up comedian. Arngrim's father, Thor Arngrim, was a well-known Hollywood manager. Her mother, Norma MacMillan, was a well-known voice actress, who provided the voices for characters on Casper the Friendly Ghost, Gumby, Davey and Goliath, and many other beloved animated programs. Her brother Stefan Arngrim was also a child actor. Arngrim is possibly best known as a former child star, playing the role of Nellie Oleson in the NBC television series Little House on the Prairie. She had originally auditioned for the role of Laura Ingalls, and later Mary Ingalls, on Little House on The Prairie, but received the role of Nellie Oleson. Arngrim lives in Los Angeles now with her musician husband, Robert Paul Schoonover. In 2010, she published her autobiography, titled Confessions of a Prairie Bitch: How I Survived Nellie Oleson and Learned to Love Being Hated. (Bowker Author Biography)
Alison Arngrim played Nellie Oleson on Little House on the Prairie from 1974 - 1982 (104 episodes). Alison wrote an official bio on the Internet Movie Database. Her book, Confessions of a Prairie Bitch is very well written and one of the best of the Little House memoirs. I highly recommend it. Click on the image for a link to Amazon to purchase it.
