Ted Kaczynski was a child prodigy who enrolled in Harvard at 16 and graduated in 3 years. He completed his post-grad at Michigan, won an award for his thesis, and became the youngest math professor ever at UC Berkeley. He later retired to a cabin in rural Montana and became the Unabomber.
It's important to point out that he was basically emotionally abused by researchers (apparently paid in part by the government) and never really recovered from it. Also that his manifesto (and later works, while in prison) are genuine works of philosophy by a person who really shouldn't ever be let out into society again. Kaczynski is a really interesting guy.
