Peggy Knudsen was born on April 27, 1923, in Duluth. Her parents were Conrad, a Duluth firefighter, and Helen. They lived in the Stratford Apartments at 18th Avenue East and 4th Street. As a child, Peggy studied the violin and also read extensively about the theater. She attended high school at Stanbrook Hall (College of St. Scholastica), taking part in musical and theatrical activities in her spare time. While in high school, she also won roles in two plays presented by the Little Theatre of Duluth, playing Blossom in “Susan and God” and Kendall Adams in “Stage Door” in 1939 and 1940 respectively. Her father died of a brain hemorrhage at the age of 46 in 1940. She graduated from Stanbrook Hall in 1941. Later that year, because of Peggy’s talent and interest in acting, her mother moved them to Chicago. Peggy soon landed a leading role in “Woman in White,” a popular daytime radio program. In 1942, she was hired to replace Jo Ann Sayers in the starring role of “My Sister Eileen” on Broadway. After completing the season in that role, she moved to Hollywood and signed a contract with Warner Brothers. She appeared in “Never Say Goodbye,” ” Humoresque,” “The Big Sleep” (with Humphrey Bogart), “Stallion Road,” “My Wild Iris Rose,” “Unchained,” and “Good Morning, Miss Dove.” In the 1950s and early 1960s, she made numerous TV appearances in such shows as “Your Show Time,” “Alfred Hitchcock Presents,” “Perry Mason,” “Bat Masterson,” and “Ozzie and Harriet.” Peggy was married twice, with both marriages ending in divorce. She had three daughters, Peggy, Molly, and Janice. She suffered from crippling arthritis in her later years and worked to support the Arthritis Foundation. She died in Encino, California, on July 11, 1980.
