David Lance Arneson (Oct 1, 1947 - Apr 7, 2009) was a game player, game designer, and game entrepreneur. He was also a true gentleman and a dear friend. As one of the co-designers of the Dungeons and Dragons game, he started something that is much bigger than all of us. It was not only a new game, but a new KIND of game and it spawned an entire industry. Without Dave, it never would have happened. He taught, lectured, designed games, and started at least three companies. He won several awards, including the Academy of Adventure Gaming Arts & Design's Hall of Fame (Origins) in 1984. In 1984 he married Frankie Ann Morneau and they had one daughter, Malia. In addition to Dungeons & Dragons, games or scenarios he wrote or co-authored include Don't Give Up The Ship, Blackmoor, Dungeon Master's Index, First Fantasy Campaign, Adventures in Fantasy, Robert Aspirin's Thieves World, Citybook II, DNA/DOA, Case of the Pacific Clipper, and more. We are all much better off for his time on earth, but the world is less than it was, with him gone. I never knew him to be rude to a fan, or turn down a friend in need. In fact, I believe his last words to me were 'Let me know if there's anything I can do for you.' I wish there was something I could do for you, my friend. Good bye, and may God bless you. -- Rick Loomis

From the Pioneer Press piece:
Dave Arneson was a master dreamer.
His daughter thought every girl grew up with dragons and fairies.
His father couldn't figure out why the college kids in his St. Paul basement weren't raiding the liquor cabinet.
But Arneson — who in 1974 co-created Dungeons & Dragons, the best-known and best-selling role-playing game of all time — molded fantasy in such a way that many lament him as the "unsung hero" of the gaming industry.
