Dave Arneson, Co-creator of Dungeons and Dragons

Geeks everywhere mourn the passing of Arneson who, with Gary Gygax, created the popular fantasy game Dungeons & Dragons, in the early 1970s. Arneson later went on to start a second career as an educator with a focus on using gaming as an instructional tool. (Gygax died in 2008.)
