High Quality Content by WIKIPEDIA articles! Professor John Nerdelbaum Frink, Jr., or simply Professor Frink, is a recurring character in the animated television series The Simpsons. He is voiced by Hank Azaria, and first appeared in the 1991 episode "Old Money". Frink is Springfield`s nerdy scientist and professor and is extremely intelligent, though somewhat mad and socially inept. Frink often tries to use his bizarre inventions to aid the town in its crises but they usually only make things worse. His manner of speech, including the impulsive shouting of nonsensical words, has become his trademark.
