Also known as conway: John von Neumann professor of math at Princeton. Really intelligent mathematician who sits around in his office all day and plays games. Discovered the surreal numbers (Donald Knuth wrote a great Alice and Bob dialogue on this) by watching Go. Nine in ten geeks have coded his Game of Life. Work is in combinatorics, knot theory, number theory, group theory, algebra, and logic.

Editor's note: John Conway died on April 11th, 2020, from complications secondary to infection with Covid-19.
