Gary Gygax, the co-creator of Dungeons & Dragons, died on this date in 2008 at the age of 69. While many people roll their eyes dismissively at the mere mention of D&D, his death garnered a surprising amount of publicity at the time (including an obituary in The New York Times that you can read HERE), which included glowing tributes to the broader influence of his creation. My favorite line in that regard was in his obituary in The Economist, which noted that the Wikipedia entry on D&D was twice as long as their entry on Proust.
Before he died, Gary Gygax appeared in an episode of Futurama, a 2 minute clip of which I've embedded below. ("Greetings!" he says, while rolling some some dice and pausing to eyeball the results. "It's a pleasure to meet you!")
