John Gregory Betancourt

Betancourt's father is Felipe Pablo "Philip" Betancourt, an archeologist. His brother Michael Betancourt became a critical theorist.

When he was a child, the Betancourt family spent summers in Greece, especially Crete, where his father worked on the excavation at Kommos in the 1970s, and Pseira in the 1980s. There the younger Betancourt developed a love for reading and discovered such diverse writers as Clark Ashton Smith, Michael Moorcock, and Jack Vance through books imported from the United Kingdom. He said of this time, "When I ran out of stories, I made up my own to keep myself entertained. I can trace the impulse to become a writer to age fourteen, when I spent most of a summer writing sequels to classics like Treasure Island."

Betancourt's first published work was a poem, "The Argia," in Space & Time magazine at age 15. At age 16, he made his first professional sale, "Vernon's Dragon," to the anthology 100 Great Fantasy Short-Short Stories, edited by Isaac Asimov, John F. Carr, and Martin H. Greenberg. He began The Blind Archer, at age 17, finished it at age 18, and sold it to Avon Books as his debut novel at age 19. He graduated from Temple University with a Bachelor of Arts.

Betancourt has alternated between writing and editing throughout his career. He worked for Amazing Stories as an assistant editor from 1985 to 1987. When the Philadelphia office shut down, he co-founded a literary agency with George Scithers and Darrell Schweitzer. A year later, Betancourt, Scithers, and Schweitzer licensed the name Weird Tales from Weird Tales, Ltd. and revived the magazine. Betancourt worked as an editor there until 1990.

Betancourt married Kim Betancourt (née Hermo) in 1989, and they moved from Philadelphia to Newark, New Jersey. He founded Wildside Press in 1989 to publish a collection of essays by Fritz Leiber designed to commemorate Leiber's appearance as Principal Speaker at Philcon that year. The book, Fafhrd & Me sold out quickly, and Betancourt decided to publish additional titles as a hobby.

Betancourt was named science fiction editor for Byron Preiss Visual Publications in 1990. He worked for Byron Preiss for 7 years, rising to senior editor, before leaving to write full-time and take care of his and Kim Betancourt's first child. This marked the beginning of his most prolific period as an author.

Betancourt also continued to publish books through Wildside Press during this period, using local short-run printers and Pulphouse Publishing to print new titles. Some of the limited editions, particularly titles by Mike Resnick, are impressive efforts. The limited editions of Resnick's Lucifer Jones series are bound in such exotic materials as Spanish cork, French leopard-patterned cloth, and leather. The limited editions he published of Bradley Denton's two short story collections are bound in Spanish snakeskin-patterned cloth and elephant-hide paper. The lettered editions have mahogany slipcases. The Denton collections won a World Fantasy Award for Best Collection of the Year.

Weird Tales was sold to Betancourt in late 2005. He has continued to publish the magazine through Wildside Press. In 2006 he hired Stephen H. Segal as editorial director of the magazine; Segal subsequently recruited Ann VanderMeer as fiction editor. In 2009, Segal and VanderMeer won a Hugo Award for Weird Tales in the category of Best Semiprozine. The magazine was also nominated for a 2009 World Fantasy Award.
