Edna Krabappel a cartoon character from the animated television series The Simpsons, who was voiced by Marcia Wallace until her death in 2013. She is the teacher of Bart Simpson's 4th grade class at Springfield Elementary School, and Ned Flanders's wife in later seasons. Krabappel was the only character that Wallace voiced on a regular basis. Following Wallace's death, the show's producers announced their intention to retire the character. Episodes featuring Edna since then have been small no-dialogue cameos, until the epilogue (which includes Wallace's voice) of the 25th season episode "The Man Who Grew Too Much".
Edna Krabappel holds a Master's from Bryn Mawr College. She is a grumpy and jaded caricature of the American public school system. In "The Seemingly Never-Ending Story", it is revealed that she was once a very optimistic woman who genuinely wanted to help people in need. It would seem that after years of frustration thanks to the school, and Bart Simpson in particular, this wore away. There is some inconsistency about Edna's origins. She is said to have come to Springfield to begin teaching in "The Seemingly Never-Ending Story". However, in a case of retconning, she can be seen in "Springfield Up" as a student running through the background at Springfield High School while a young Chief Wiggum is filmed carrying out his duties as a hall monitor, as part of the documentary featured in that episode. Krabappel smokes heavily, especially during school hours. In the episode "Grade School Confidential", she and Principal Skinner have a romance after they are invited to Martin Prince's party. They are witnessed kissing in Martin's playhouse by Bart. Principal Skinner then sends Bart to relate a message to Edna in front of his classmates who laugh at him making him furious. He then shows them what they are doing and tells them not tell about their romance to anyone, especially Superintendent Chalmers. Unknown to Bart they lose their jobs when Superintendent Chalmers finds out about their affair via Chief Wiggum and they lock themselves in the school with Bart until they are reinstated. They also apologize to Bart for embarrassing him. After getting their jobs back they resume their romance in the Janitor's closet. In "Bart Gets a 'Z'", she is fired from teaching after getting drunk (Bart spiked her coffee) and decides to open a muffin store. She is later rehired when the substitute teacher gets drunk. In "Moms I'd Like to Forget", she gets into a fight with the fifth grade teacher, Mike who talked badly about her students, leading to a massive teacher brawl. In "The Ned-Liest Catch", she is suspended from teaching for spanking Bart and is put in the Teacher Holding Facility; when Bart attempts to free her, she falls off a ladder but is saved by Ned Flanders.
