I have a complete set of the American chess quarterly but it covers the decade before Robert James Fischer won the World championship in 1972, never the less, its pretty awesome, has contemporary prints of what looks like him in his moms kitchen in Brooklyn.
@batgirl, check out the December 2019 issue of Chess Life. There are articles about the 80 years US Chess has existed and I believe you'll find a lot about the Fischer membership boom as well as the decline. There's a lot of great US Chess history in that issue.
Thanks for the tip. Unfortunately, I only have Jan,-Jul. of 2019.
