Lake Geneva Tactical Studies Association

From Wikipedia, the free encyclopedia

The Lake Geneva Tactical Studies Association (LGTSA) was a prominent wargaming club active in Lake Geneva, Wisconsin during the 1960s and 1970s. Its membership included Gary Gygax, Rob Kuntz, Mike Reese, Leon Tucker, and Don Kaye. When Gygax and Kaye founded Tactical Studies Rules (later TSR, Inc.) in 1973 in order to publish Dungeons & Dragons, they echoed part of the name of the LGTSA in the name of their new company.
