Summary: actress who played petty, gossiping Harriet Oleson on the long-running TV series Little House on the Prairie while nasty Nellie Oleson (played by Alison Arngrim) was the character viewers most loved to hate on NBC from 1974 to 1983 (her cruel mother Harriet was just as awful, never missing a chance at small-town social climbing or petty backbiting) as the Olesons stood on contrast to the warm, loving members of the Ingalls family who were the show's focus and often the Oleson's targets, who remained with the show for its entire run as did Michael Landon (d. 1991) and Melissa Gilbert, who played young Laura Ingalls.
