Stumbled upon this great documentary on four famous mathematicians – Georg Cantor, Ludwig Boltzmann, Kurt Gödel and Alan Turing. This documentary talks about their extraordinary intellectual powers and how it drove them insane, eventually leading them to committing suicide.
Fun fact: Turing was conceived in Chhatrapur, Orissa, India. His father, Julius Mathison Turing, was a member of the Indian Civil Service. (via Wikipedia)
