While not as famous as Gary Gygax, who passed away in March of last year, Arneson was a driving force behind D&D’s creation and his contribution to the world of adventure gaming should not be underestimated. It was Arneson’s spark that transformed Gygax’s game Chainmail into the first edition of D&D, and begat everything that followed.
Arneson had to fight to get credit for his contributions, filing multiple lawsuits (later resolved out-of-court) against Gygax over crediting and royalties. He nonetheless did return to TSR in the mid-’80s to work with Gygax again. Following that, he began a second career as an educator, working in several schools with a particular focus on how to use gaming as an instructional tool.
Arneson suffered a stroke in 2002 and was soon after diagnosed with cancer. He finally lost his battle with cancer last night, surrounded by his family, in St. Paul, Minnesota. Gamers everywhere owe him a certain debt of gratitude for his work. He will be sorely missed.
