Overview

Katherine "Scottie" MacGregor (born Dorlee Deane MacGregor; January 12, 1925 – November 13, 2018) was an American actress and dancer whose performance as Harriet Oleson on the television series Little House on the Prairie made her a familiar face to television audiences. Born in Glendale, California, she worked across stage and screen and was often remembered for her comic timing and distinctive characterization.

Early life and stage career

MacGregor's early years included training in dance and work in regional theatre and touring productions. She used the nickname "Scottie" professionally and built experience in live performance before moving into television. Her dance background and stage discipline informed the expressive physicality she later brought to screen roles.

Little House on the Prairie and screen work

MacGregor achieved widespread recognition during the 1970s and 1980s for her recurring role as Harriet Oleson on the popular series Little House on the Prairie. The character served as a comic antagonist and small‑town foil to the Ingalls family, often providing both humor and dramatic tension. While most closely associated with that part, MacGregor's résumé included other television appearances and stage engagements over several decades.

Later life, writing and legacy

In later years MacGregor stepped back from frequent screen appearances and devoted time to writing and university and community theatre activities. She was regarded by fans and colleagues for creating a memorable, layered television persona: a character who could be petulant and scheming but also oddly human and entertaining. Her performance remains a touchstone for portrayals of comically cantankerous figures in family dramas.
