Growing up in a family active in the entertainment field, Arngrim was introduced to show business at an early age. She began her career as a child model and actress, appearing in various television commercials. Her brother, Stefan Arngrim, was also a child actor, known for his role in the 1960s series "Land of the Giants."

Breakthrough Role: Nellie Oleson on Little House on the Prairie

Alison Arngrim achieved widespread recognition in 1974 when she was cast as Nellie Oleson in the NBC historical drama series Little House on the Prairie. Originally auditioning for the roles of Laura and Mary Ingalls, she ultimately secured the part of Nellie, a spoiled and mean-spirited character whose antics became iconic. Her portrayal contributed to the show's popularity during its run and established her as a cultural symbol of the "bad girl" persona of 1970s television.

Arngrim remained with the series for seven seasons, from 1974 to 1981, and her character remains one of the most memorable in the show's history. Her nuanced portrayal of Nellie Oleson earned her both lasting fame and a complex relationship with the television audience.

Later Career and Memoir

In 2010, Arngrim published her memoir, Confessions of a Prairie Bitch: How I Survived Nellie Oleson and Learned to Love Being Hated. The book details her experiences growing up in the entertainment industry, her time on Little House on the Prairie, and her personal journey toward resilience and self-acceptance. The memoir was well-received for its candid tone and blend of humor and insight.

Personal Life

Arngrim has been married twice. Her first marriage was to writer Donald Spencer, which took place in the late 1980s. She later married musician Robert Paul Schoonover. Beyond her work in entertainment, Arngrim has become an advocate for various causes, including child abuse prevention and HIV/AIDS awareness.
