At its inception around February and March 1970, it was originally known as the Lake Geneva Tactical Games Association, though this name gave way to 'LGTSA' within weeks.
[1] Its early membership included Gary Gygax, Terry and Rob Kuntz, Ernie Gygax, Jeff Perren, Mike Reese, Leon Tucker, and Don Kaye.
[5] When Gygax and Kaye founded Tactical Studies Rules (later TSR, Inc.) in 1973 to publish Dungeons & Dragons, they echoed part of the name of the LGTSA in the name of their new company; Blume later soon joined the partnership.
The LGTSA continued to exist as a wargaming group well after the publication of Dungeons & Dragons.
