E. Gary Gygax was one of the gaming world's most influentual figures. He was Born in Chicago in 1938, he was playing chess at age six and with miniatures by age fifteen. He founded GenCon, now the world's largest and longest-running annual hobby gathering, back in 1968. His list of game-design credits alone would fill a page. Everyone knows he co-created Dungeons & Dragons -- and changed the face of role-play gaming forever -- but not as many know that he's helped create nine other games (and several rules sets for still more games) and written thirteen books including seven bestsellers and two "how-to" books on gaming. His work on Advanced Dungeons & Dragons includes no less than four rule books, two supplements, three accessory sets, and seventeen (!) adventure modules.
