Came across this wikipedia article on Kin Ung-Yong (mentioned in this Reddit discussion on why The Big Lebowski is so great): Kim was in the Guinness Book of World Records for highest IQ (210), could read four languages by the age of 3, and earned his PhD in Physics before 16. However, he settled for being a professor in civil engineering at a mediocre university, just so he could live a normal life.
