The Simpsons pays tribute to late actress Marcia Wallace

Wallace's character will be "retired" following the actress's death

Marcia Wallace, the late actress who provided the voice of schoolteacher Edna Krabappel in The Simpsons, has been remembered in its latest episode.

Sunday's edition of the series began with Bart Simpson at the blackboard, standing beneath the poignant message: "We'll really miss you Mrs. K."

Wallace died of complications from pneumonia on 25 October at her home in Los Angeles at the age of 70.

The actress won an Emmy in 1992 for her work on the long-running animated show.

Sunday's edition of The Simpsons was preceded on the Fox channel in the US by a re-run of 2011 episode The Ned-liest Catch.

Wallace appeared in 178 episodes in all, voicing grumpy fourth-grade teacher Edna in all but three of them.

The actress's death was confirmed on 26 October by The Simpsons' executive producer Al Jean, who said she had been "brilliant and gracious".

"She was beloved by all at The Simpsons and we intend to retire her irreplaceable character," he said in a message on Facebook.
