Marcia Wallace, the voice of Edna Krabappel on The Simpsons, has died. She was 70.
The longtime TV actress' credits ranged from playing a wise-cracking receptionist on CBS' The Bob Newhart Show to appearances on Candice Bergen's Murphy Brown.
Simpsons executive producer Al Jean said in a statement Saturday, Oct. 26, that her death is a terrible loss. He said Wallace's "irreplaceable character," the fourth-grade teacher who has to deal with Bart Simpson's constant antics, would be retired from the show.
"Earlier we had discussed a potential storyline in which a character passed away; this was not Marcia's Edna Krabappel," Jean said.
Jean said Wallace was "beloved by all at The Simpsons."
