Today’s trivia question: Every winner of the Best Fan Writer Hugo has made at least one professional sale, but two winners have never sold a science fiction story. Can you name them?

The winners since the creation of the category in 1967 are: Terry Carr, Richard E. Geis, Mike Glyer, Dave Langford, Cheryl Morgan, Alexei Panshin, John Scalzi, Bob Shaw, Wilson Tucker, Harry Warner Jr., Ted White and Susan Wood.

Most of the names are easy to rule out because their record in the sf field is so well known.

Wilson Tucker won the 1970 Best Fan Writer Hugo, then had Year of the Quiet Sun nominated as Best Novel in 1971.

Scalzi’s novel Old Man’s War and its sequels have received Hugo nominations.

Dave Langford’s “Different Kinds of Darkness” won Best Short Story in 2001.

Bob Shaw’s classic short story “Light of Other Days” received a Hugo nomination in 1967. He didn’t get around to winning the Best Fan Writer Hugo until 1979 (and again in 1980.)

Ted White’s first novel was written in collaboration with another Best Fan Writer winner, Terry Carr. Invasion from 2500 (1964) was published under the pseudonym Norman Edwards. Ted went on to write lots of other novels under his own name.

Terry Carr, in the middle of a run of seven other nominations for his fan writing and fanzines (Fanac, Lighthouse) had a short story nominated for the Hugo in 1969, “The Dance of the Changer and the Three.” The year Terry finally won the Best Fan Writer Hugo, 1973, he was also nominated for Best Professional Editor (in the category’s debut), and it was as an editor he won his last two Hugos (1985, 1987).

Alexei Panshin won the first Best Fan Writer Hugo in 1967. He declined his nomination in 1968, hoping to set an example for future winners. He also had great success as a pro. His novel Rite of Passage received a Hugo nomination in 1969 and won the Nebula.

Harry Warner Jr. had 11 short stories published in the mid-1950s (and grumbled when that was discovered by his neighbors in Hagerstown — see the link below in comments).

Richard E. Geis has sold any number of erotic sf novels.

I trail this parade at a respectful distance, with one pro sale that appeared in Mike Resnick’s Alternate Worldcons.

That leaves two winning fanwriters to account for: Cheryl Morgan and Susan Wood. Cheryl has made nonfiction sales, but the Locus index lists no fiction. Susan Wood published scholarly work about the sf field, but no stories. So Morgan and Wood are the answer. (Subject to correction, as always…)

Update 10/12/2009: Of course Harry Warner sold short stories — text corrected. Thanks to Patrick Nielsen Hayden for the assist. Update 10/13/2009: And to Dave Langford for catching mistakes about Shaw’s story I have been helplessly repeating since, oh, 1967, although they ought to be avoidable  — I can always remember the exact year “Neutron Star” won its Hugo. 10/18/2009: Alexei Panshin’s comment gives the real reason he turned down his Best Fan Writer nomination in 1968.
