Jonathan "John" I.Q. Neidelbaum Frink, Jr., B.Sc., Ph.D. M.R.S.C., C.Chem, better known as Professor Frink and once referred to as Doctor Frink, is Springfield's 40-year-old local scientist and college professor, and is extremely brilliant, though somewhat socially inept. Frink often tries to use his bizarre inventions to aid the town in its crises, but they usually only make things worse.

Biography
Born sometime in the 1940's, Frink is Springfield's local mad scientist. He has a trademark mannerism of using tourettes-like gibberish when excited, such as "GLAYVIN!" and shouting other words that have no relevance to the situation at hand. He also occasionally refers to the importance of remembering to "carry the one" in various mathematical calculations. He is almost never seen without his glasses and has only taken them off once.

Frink is said to have an IQ of 197; 199 before he sustained a concussion during the collapse of Springfield's brief intellectual junta. He is a member of the Springfield Mensa and a college professor at Springfield Heights Institute of Technology.

Frink is fond of flubber, a material with enhanced bounce properties which his basketball shoes are made out of.

Professor Frink is the inventor of, among other things, hamburger earmuffs, the flying motorcycle and the 8-month after pill. Some of Frink's inventions, such as the automatic phone dialer, work better than others, such as his radio-controlled plane, which carries babies as passengers under their parents' control, or a secure house that sprouts legs and runs away from potential danger (the legs of which often collapsed causing the house to crash to the ground and catch fire). Frink has also discovered and cured "Frink's Disease" and discovered "Frinkonium."

In the 1960s, Professor Frink made napalm to drop on Da Nang. He once predicted that computers would be so large and so expensive that only the five richest kings of Europe would own them, a paraphrase of Thomas J. Watson's misquote.

Professor Frink has frequent contact with Lisa Simpson than the rest of the Simpsons family because she is more interested in science and makes more frequent visits to places such as the Natural History Museum and the Observatory.

Family
Frink has a wife, though they may be separated or divorced, and a young son who looks similar to him. When his son crashed through a window during a demonstration of a remote controlled airplane, he says "my wife is going to kill me", but his son is seen alive later, (this is either a different son or his son survived the accident).

His father (voiced by Jerry Lewis) appears in the Treehouse of Horror XIV. Professor Frink reanimates his father, Frink Sr, so that they could reconcile and see him (Frink Jr) receive the Nobel Prize. Alas Frink Sr has become Frinkenstine and begins to harvest body parts to improve himself. After see the anguish his actions have caused his son, Frink Sr stops being the monster and tries to make amends only to become the monster again when he sees all the nice big juicy brains dripping with knowledge at the Nobel Prize ceremony and going on a killing spree. With that Professor Frink did some calculations, found the weakest spot, and killed his father by kicking him in the crotch. Though all was not a loss Professor Frink was able to save his fathers soul in a box that he can converse with.

Future
In "Future-Drama", an episode set eight years into a possible future of Bart and Lisa's, a bespectacled skeleton dressed in a lab coat is observed hanging on a rope from a rafter in Frink's basement laboratory—indicating the professor has committed suicide in the interim - although this could be a clone or his aforementioned son -, his death gone unnoticed by family and friends. However, another episode set further in the future, "Lisa's Wedding", shows him alive and well as he leads a team trying to discover the cure for seventeen stab wounds in Mr. Burns' back, stating "Well, we're up to fifteen!".

Treehouse of Horror
"Frink out"

- Frink

In Treehouse of Horror XIV, it is revealed that Frink had a strained relationship with his father (voiced by Jerry Lewis). Frink said they got along like "positrons and antineutrinos." The senior Professor Frink was a "he-man" scientist who, according to his son, worked on the atom bomb by day, slept with Marilyn Monroe by night, and sold secrets to the Russians at lunch. Frink brought his father back to life after he died from a Shark Attack, but he went on a rampage and younger Frink was forced to kick the elder in the nuts, killing him. It is indicated in this episode that their shared middle name is "Neidelbaum". The two rebuild their relationship when the elder Frink is proud of his son for stopping him like a man. Frink had his father's soul put into a machine.

The Simpsons Game
In The Simpsons Game, he lives inside the Game Engine and marries a Koopa Troopa from Super Mario Bros.

Behind the Laughter
Professor Frink is voiced by Hank Azaria. The character was originally written as a mad scientist. However, when cast member Hank Azaria ad-libbed a voice for Frink, he did an impression of Jerry Lewis's The Nutty Professor character, and the writing staff started making Frink more of a parody of Lewis. Frink was named after writer John Frink; however, that was before he became a writer for the show. Frink was originally animated without his buckteeth. The nonsensical utterances that Frink makes are written in the scripts as "Frink noise".

Trivia

 * His popularity has led to him giving name to a computer programming language.
 * To him, the word "Nerd" stands for "Not Even Remotely Dorky". Possibly, because he doesn't want to be belittled. ("Eternal Moonshine of the Simpson Mind")
 * Despite having one known son, Frink seems to be a sperm donator as seen in Selma's Choice.
 * He appears to be the only person in Springfield who knows what a cube is as seen in Treehouse of Horror VI, and as a result, he claims to have invented/discovered it, and names it a "Frinkahedron". However, this is non-canon.
 * He is an insectivorian.
