Diablerie was a science fiction fanzine by Bill Watson.
The first issue of Diablerie appeared in May 1944.
According to Terry Carr (Entropy), writing in his column "Entropy Reprint", in Energumen #10, from May 1972; "Bill Watson was a San Francisco fan of the forties; his fanzine DIABLERIE appeared on all the polls for top fanzines of the time, but it's forgotten by most everybody but Harry Warner and me today. It doesn't deserve its obscurity; it was an exceptionally neatly produced fanzine, mimeographed with colour headings and illustrations. Some of the artwork, such as a drawing by Ronald Clyne, was offset and pasted in; and the "About Our Contributors" section was illustrated by pasted-in photographs."
Contributions included poetry by Banks Febane, and articles by Lou Goldstone, F. T. Laney (The Acolyte), and Jack Wiedenbeck.
Also contributing was E. Hoffman Price. Terry Carr says, "For Diablerie, self-styled as "fandom's Esguire," he wrote connoisseur articles on brandies, tobaccos and so on, and a re- miniscence about his friend Robert E. Howard." E. Hoffman Price was perhaps the only science fiction writer or fan to actually meet Howard.
Bill Watson also co-published, with George Ebey, the science fiction and horror poetry fanzine Sappho.
