Edna Krabappel was a recurring character and a 4th-grade teacher at Springfield Elementary School up until her unspecified death in 2013. She lived at 82 Evergreen Terrace, but later moved to 744 Evergreen Terrace, after marrying Ned Flanders, the widower of Maude Flanders. Outside school, Edna was portrayed as a typical mid-life single adult, heavy smoker, gambler, and occasional solitary drinker trying to find the right man. She had numerous affairs with many Springfieldians; her recurring choice always being Principal Skinner, usually out of pity rather than affection. From Season 23 until her retirement in Season 25, Edna Krabappel was married to Ned Flanders. She was 41 years old and she was born in 1949. Al Jean announced Edna would be retired due to the death of Marcia Wallace (her voice actress) on October 25, 2013. The process began in 'Four Regrettings and a Funeral' when 'We'll really miss you Mrs. K.' was shown on the chalkboard gag during the title sequence, which premiered nine days after Marcia's death. In the Season 25 episode 'The Man Who Grew Too Much', Ned and Nelson mentioned that they miss her. Her passing was indicated by Ned wearing a black armband, but was never shown on-screen.
