Jean Stapleton (January 19, 1923 – May 31, 2013)

Stapleton was a trained mezzo-soprano. She made
her operatic debut in 1984 at the Baltimore
Opera Company in Bernstein's Candide.

"The daughter of an opera singer and businessman, Stapleton grew up on Long Island and in New York City. It was there during the early 1940s, while working as a typist for the British War Ministry Office, that she began her career in theater. Stapleton made it to Broadway in the production In the Summer House in 1953, the same year of her television debut on the daytime drama Woman With a Past. Other big stage roles followed, including in Bells Are Ringing and Damn Yankees. She also did more and more television, including appearances on shows such as Philco TV Playhouse and Dr. Kildare. Her breakout role was as Edith Bunker, the conscience of All in the Family as the kindhearted foil to husband Archie, played by the late Carroll O'Connor."
