John F. Nash, Jr. — 1928-2015

He's famous for a number of reasons, not least of which being the subject for the movie "A Beautiful Mind."

An obituary, at the New York Times, "John F. Nash Jr., Mathematician Whose Life Story Inspired ‘A Beautiful Mind,’ Dies at 86."

FTFY. RT @TheEconomist: John Nash's work on game theory is now part of almost every social scientist's tool-kit http://t.co/EofJmrBosS
