Overview
Edna Krabappel-Flanders is a fictional character from the American animated sitcom The Simpsons, voiced by Marcia Wallace. A 4th-grade teacher, she teaches Bart Simpson's class at Springfield Elementary School. In the twenty-third season, she marries Ned Flanders.
Following Marcia Wallace's death in 2013, the show's producers announced that her character would be retired. The epilogue of the season 25 episode "The Man Who Grew Too Much" marks Edna Krabappel's final original speaking role.
Profile
Edna Krabappel holds a Master's from Bryn Mawr College. She is a surly, 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.
