Voiced by Glenn Close in some episodes, Homer's mom appears periodically and is revealed to be a political activist. What is her name?

Mona Penelope Simpson is the estranged wife of Homer's dad Abe, and she first appears in the 1991 episode "Oh Brother, Where Art Thou?". In the episode "Mother Simpson", it was established that Homer believed that his mother was dead, which was a lie his father told him. In truth, she was on the run from the law since she once destroyed Mr. Burns's biological warfare lab in an act of political activism.
