Sign Guy

Your friendly neighborhood Sign Guy is a professional nerd from a family of professional nerds who occasionally convinces people he’s competent enough to present things at conventions. When not talking at crowds, he works with satellites, ships, and dives far deeper into pulp-era sci-fi than is medically advisable.

Alan Smale

Alan Smale writes alternate history, historical fantasy, and hard SF. His novella of a Roman invasion of ancient America, “A Clash of Eagles”, won the Sidewise Award for Alternate History, and his novels set in the same universe, Clash of Eagles, Eagle in Exile, and Eagle and Empire (2015-2017) are available from Del Rey. His “Roman baseball” collaboration with Rick Wilber, The Wandering Warriors, came out from WordFire Press in 2020. Hot Moon, his alternate-Apollo “techno-thriller with heart”, set entirely on and around the Moon, was launched by CAEZIK SF & Fantasy in 2022, with sequels Radiant Sky in 2024 and Burning Night in 2025.

Alan has sold over fifty stories to Asimov’s and other magazines and anthologies, and his short story “Gunpowder Treason” earned him a second Sidewise Award in 2022. His non-fiction essays have appeared in Lightspeed, Journey Planet, and Galaxy’s Edge.

Alan grew up in Yorkshire, England, and earned degrees in Physics and Astrophysics from Oxford University. Until recently he performed astronomical research at NASA’s Goddard Space Flight Center, and served as director of an astrophysical data archive. He also sings bass with high-energy vocal band The Chromatics, and is co-creator of their educational AstroCappella project, spreading astronomy through a cappella in schools across the country.
