The Golden Age of Science Fiction: The 1973 Hugo Award for Best Amateur Magazine: Energumen
The Hugo Award for Best Fanzine was first awarded in 1955 to Science-Fiction Times, edited by James V. Taurasi, Sr. and Ray Van Houten. That was the second year of the Hugo Awards (which began in 1953 and skipped 1954.) It has been awarded every year since then (except 1958) in some form – the name has varied a bit, from Fanzine to Fan Magazine to Amateur Magazine, before settling on Fanzine.
In 1973 the Hugo for Best Amateur Magazine went to Energumen, edited by Mike Glicksohn and Susan Wood Glicksohn. Energumen ran for 15 issues (plus two supplements) from 1970 through 1973, with an additional issue in 1981, published after Susan Wood’s death, aged only 32, in 1980. The fanzine essentially ran for the duration of the marriage of Mike and Susan. Mike Glicksohn died in 2011. Both editors received Hugo Nominations as Best Fan Writer – Mike Glicksohn in 1977, and Susan Wood 8 times, winning in 1974, 1977, and posthumously in 1981.
I can’t say I read Energumen in my Golden Age. Alas, the first fanzines I read were a couple of years later – Locus and Science Fiction Review (aka The Alien Critic), both in 1975 (or maybe late 1974.) So I took the time to head to efanzines.com and look through the 1972 issues of Energumen. The magazine was nominally quarterly, and indeed four issues appeared in 1972, numbers 11 through 14. (The thirteenth issue announced that #15 would be the last.)
