254 IQ Genius Stuck Being a Janitor

Will Hunting, a janitor at M.I.T., has a gift for mathematics, but needs help from a psychologist to find direction in his life.

William Sidis, Author and Professor — IQ 250-300
In 1909, William Sidis broke the record for the youngest person ever to be accepted into Harvard University. He was eleven years old.

Sidis would go on to write “The Animate and the Inanimate,” about thermodynamics and the origins of life. He is said to have spoken 25 languages, and at one point he even invented his own.

If the claims about him are true, he may have had the highest IQ ever. Critics propose that 254 was actually just the place where he fell in the ranking on the exam.
