A nice feature about one of the heroes of computer science, Donald Knuth, in this month's Stanford Magazine. When I was an undergrad, a friend introduced me to him as "the god of computers", but it wasn't until later that I realized how influential he was. He wrote Tex and Metafont, two early typesetting apps that got me interested in fonts.
Two important facts about him that explain everything: he's from Wisconsin and he's a devout Lutheran. The article adds some more facts, like that he (still) writes several computer programs each week. I wonder what kind of computer he uses?
