The origin of the term “steampunk” came from author K. W. Jeter in a letter from April 1987 to the science fiction magazine, Locus;

Dear Locus,Enclosed is a copy of my 1979 novel Morlock Night; I’d appreciate your being so good as to route it Faren Miller, as it’s a prime piece of evidence in the great debate as to who in “the Powers/Blaylock/Jeter fantasy triumvirate” was writing in the “gonzo-historical manner” first. Though of course, I did find her review in the March Locus to be quite flattering.

Personally, I think Victorian fantasies are going to be the next big thing, as long as we can come up with a fitting collective term for Powers, Blaylock and myself. Something based on the appropriate technology of the era; like “steampunks”, perhaps…
