Gygax was even Silent Gen. So were the Rolling Stones, but Woodstock is seen as a Baby Boomer event.
D&D was a very much a boys & young men phenom in the 80s, is how I always understood it. While I started just before the peak years/sales of the famed Red Box, and thus often gamed with "older" (OMG, actual adults) players, I'd always had the impression the fad was mainly among Gen X kids. If historical research shows, nope, it was just that last cohort of Baby Boomers, again, well.
