As Edna Krabappel on The Simpsons, Marcia Wallace may be the only 4th-grade teacher to have the same student for 24 years. Before that, she was beloved as Carol Kester, the lovelorn, wisecracking secretary on The Bob Newhart Show.

Wallace, who was a breast cancer survivor for 28 years, has died at age 70, according to the showrunner of The Simpsons. “I was tremendously saddened to learn this morning of the passing of the brilliant and gracious Marcia Wallace,” producer Al Jean said in a statement to EW. “She was beloved by all at The Simpsons and we intend to retire her irreplaceable character.”

That's sad.

Aww she wasn't that old. She'll always be remembered through the Simpsons.
RIP

Sad news, R.I.P.

That sucks. I certainly hope they send her off with a tribute show for the character, like they did for the man who voiced Troy McClure. Would be a nice touch. RIP.
