Her laugh will live on. Shirley Mitchell, best known as Lucy Ricardo's cackling friend on I Love Lucy, has died at the age of 94, her sister-in-law Nancy Olson told The Hollywood Reporter on Nov. 13.
Believed to be the last surviving cast member of the legendary sitcom, Mitchell passed away of heart failure at her condo in Westwood, Calif., Olson said. (Olson herself is an Oscar-nominated actress who starred in Sunset Blvd.)
Mitchell joined the cast of I Love Lucy during the third season, which ran from October 1953 to May 1954. According to THR, she appeared in three episodes as Marion Strong, the woman who set up Lucy (Lucille Ball) and Ricky (Desi Arnaz) on their first date. (Marion was originally played by Margie Liszt in one episode of season two.)
Other TV credits on Mitchell's resume included Opal Clampett on The Beverly Hillbillies, Marge Thornton on Please Don't Eat the Daisies, and Clara Appleby on The Red Skelton Show. On the big screen, she appeared in 1944's Jamboree and 1989's War of the Roses, among others.
She is survived by Olson, as well as children Scott and Brooke.
