Sad news for Simpsons fans everywhere hit the internet last week as it was revealed that Marcia Wallace–the voice of Bart’s school teacher, Edna Krabappel–had passed away. Deadline has the story that says that she died from complications of a long battle with breast cancer, while also providing an official press statement from Simpsons executive producer Al Jean.  “I was tremendously saddened to learn this morning of the passing of the brilliant and gracious Marcia Wallace,” he said. “She was beloved by all at The Simpsons and we intend to retire her irreplaceable character. Earlier we had discussed a potential storyline in which a character passed away. This was not Marcia’s Edna Krabappel. Marcia’s passing is unrelated and again, a terrible loss for all who had the pleasure of knowing her.”
