Professor Frink

39

Professor Frink's backstory involves being an eccentric, genius inventor on The Simpsons. He initially appeared evil before becoming a more nerdy character. His origins include a strained relationship with his father, Professor Frink Sr., and a family that is largely absent from the series, though he does have a wife and son who appeared in early episodes. Frink first appeared in 1991 as an evil scientist trying to get funding for a death ray. After Hank Azaria ad-libbed a voice based on Jerry Lewis, the character's personality and appearance were changed to be more like Lewis's "Julius Kelp" character, becoming a nerdy and mad scientist. His father, Professor Frink Sr., was also a scientist who was brought back to life by Frink after dying in a shark attack, but went on a rampage and was killed again. He has a son, Frink Jr., and a wife. His wife and son appeared in early episodes, but their current whereabouts are unknown. His son shares his father's mannerisms. He is a member of Springfield Mensa with an IQ of 197. He teaches at the Springfield Heights Institute of Technology. He often creates bizarre inventions that frequently cause more problems than they solve.
