Mary Margaret “Peggy” Cass (May 21, 1924 – March 8, 1999) was an American actress, comedian, game show panelist, and announcer. A native of Boston, Massachusetts, Cass became interested in acting as a member of the drama club at Cambridge Latin School; however, she attended all of high school without a speaking part. After graduating from high school, she spent most of the 1940s in search of an acting career, eventually landing Jan Sterling's role in a traveling production of Born Yesterday. Cass made her Broadway debut in 1949 with the play Touch and Go. Remembered today primarily as a regular panelist on the long-running To Tell The Truth, Cass was best known for her performance as Agnes Gooch in Auntie Mame on both Broadway and in the film version (1958), a role for which she won the Tony Award for Best Supporting Actress, and later received an Oscar nomination for Best Supporting Actress. Cass was also part of the nine member ensemble cast for the 1960 Broadway revue A Thurber Carnival, adapted by James Thurber from his own works.
