'Simpsons' Actress Marcia Wallace Dies

In addition to her role as Edna Krabappel on the Fox show, she also starred on "The Bob Newhart Show."

Marcia Wallace, the voice of The Simpsons' Edna Krabappel who earlier played the quick-witted receptionist on The Bob Newhart Show, has died. She was 70.

"I was tremendously saddened to learn this morning of the passing of the brilliant and gracious Marcia Wallace. She was beloved by all at The Simpsons and we intend to retire her irreplaceable character," said Simpsons executive producer Al Jean in a statement.

Jean addressed a storyline that was previously teased about killing off a character on the show and noted that this was not associated with Wallace.

"Cheers to the hilarious, kind, fab Marcia Wallace, who has taken her leave of us. Heaven is now a much funnier place b/c of you, Marcia," Yeardley Smith, who voices Lisa Simpson, wrote on Twitter on Saturday morning.

On Newhart, which aired on CBS from 1972 to 1978, Wallace played Carol Kester, the wise-cracking, independent receptionist in a Chicago high rise that housed the offices of psychologist Bob Hartley (Newhart) and orthodontist Jerry Robinson (Peter Bonerz). She was in 139 of the show's 142 episodes.
