From Matt Forbeck: "Through Jeff Grubb, I learned that Mike Cook passed away last week, a victim of a heart attack on the evening of his eldest son's graduation from high school. He was 60.
Mike was an executive at TSR in the '80s. Among many other things, he served as publisher of Dragon Magazine and Dungeon Magazine, and he helped design the first Buck Rogers RPG.
The memorial service is this Friday in Waukesha, WI. You can read a
