Greg Costikyan has a touching obituary for Redmond Simonsen:
Before I go into the personal bit, I'll explain why you should know Redmond's name, even though you probably don't: Redmond coined the term game designer. Before he did, we had no good term; game inventor, game author... but he put his finger on what we do. Redmond established the look for the graphics of the board wargame. Redmond wasn't the first to design a fantasy/science fiction boardgame, but he almost single-handedly established it as a successful genre... And Redmond was a kick-ass game designer in his own right. Go find a copy of StarForce: Alpha Centauri, or Sorceror.
