Katherine MacGregor

Katherine "Scottie" MacGregor (born Dorlee Deane McGregor; January 12, 1925 – November 14, 2018) was an American actress, best known for her role as Harriet Oleson in Little House on the Prairie. Katherine MacGregor was born Dorlee Deane McGregor on January 12, 1925, in Glendale, California, to Ralph S. McGregor and Beatrice E. Willard.

When Katherine was a child, her mother Beatrice moved the family to Fort Collins, Colorado, where they lived most of Katherine's early life. She graduated from Northwestern University with a major in drama and moved to New York City in 1949. She was hired by the Arthur Murray Dance Studios as a dance instructor. She studied acting under N.

Richard Nash, Sanford Meisner, and Stella Adler. She did summer stock in Lebanon, Pennsylvania as Dorlee Deane McGregor but switched to using the stage name Scottie MacGregor as her acting career advanced. When she adopted the use of Katherine as her given name is unclear but she switched from using ‘Scottie’ as she matured in age on the advice of her manager. Beginning in the 1950s, as Scottie MacGregor, she worked in theatre on and off Broadway in New York City and other locations in plays such as The Seven Year Itch and Handful of Fire, and won such uncredited parts as "a longshoreman's mother" (On the Waterfront); "Alice Thorn" (The Traveling Executioner), and "Miss Boswell" (The Student Nurses).
