Sourdough Jackson


• Who coined the term “sci-fi”?
• What widely-read 1930s non-SF novel inspired a series of stories about flying, space-traveling cities?
• Was there really a Communist front organization that produced nearly two dozen of the best science fiction authors, editors, and publishers, almost none of whom were Communists?

Perhaps the “Cliff’s Notes” of classic science fiction, writer Sourdough Jackson’s essays keep alive the books, authors, editors, publishers, magazines, and movies that made science fiction the successful subject and industry it is today.

Jackson’s love and deep knowledge of SF is obvious in That Old Science Fiction, originally published as a monthly column in DASFAx, the newsletter of the Denver Area Science Fiction Association.

That love is brought to you here, complete with a forward by Robert Vardeman, author of The Cenotaph Road and dozens of other science fiction novels.



Sourdough Jackson, a transwoman, began reading science fiction with a Jules Verne novel at age six, found SF fandom in the early 1970s, and has been deeply involved with it ever since. Early on, she met longtime Denver fan Gail Barton at a convention, and they married in 1978. This lasted until 2018, when Gail passed away.

Sourdough has been involved with convention committees, fanzine publishing, and the Denver Area Science Fiction Association, serving as that group’s secretary for twelve years. She currently edits DASFAx, the club’s newsletter. With Gail, she accumulated a huge library of SF and fantasy books. Since 2008, she has written a monthly column for DASFAx on classic science fiction, originally titled “That Old Science Fiction” and now called “Writers of the Purple Page.”

Sourdough’s own debut novel, Torpedo Junction: Rommel the Ocean Fox in the Pacific, melds a lifelong study of naval history with a love of science fiction as an alternate history of World War II.
