That's an awesome fact! I'm reading Von Neumann & Morgenstern's Game Theory and Economic Behavior now and while I'm not surprised he's gifted in other disciplines, it's amazing that someone can be so deep in so many fields.

You should read Turing's Cathedral if you are interested in Von Neumann's life.

Thanks for the recommendation. I'm actually reading the biography of Turing at the moment, so that sounds like a perfect follow-up.
