Gary Gygax
In 1967, Henry Bodenstedt created the medieval wargame "Siege of Bodenburg", which was designed for use with 40mm miniatures. Gary Gygax first encountered "Siege of Bodenburg" at Gen Con I (1968), and played the game during that convention. The rules for "Siege of Bodenburg" had been published in "Strategy &amp; Tactics" magazine, and Jeff Perren developed his own medieval rules based on those and shared them with Gary Gygax.
