A little-known early science-fiction writer, best remembered today for the novel Z-Day on Centauri, a space adventure that has survived through modern reprints and Project Gutenberg preservation.

by Henry T. Simmons
Very little reliable biographical information about this author is easy to confirm online, and that scarcity is part of the intrigue. Henry T. Simmons is associated with Z-Day on Centauri, a science-fiction novel that has remained available through modern reprints and through Project Gutenberg, helping keep the work in circulation for new readers.
Based on the surviving publication record, Simmons appears to belong to the tradition of older pulp-era or early popular science fiction, writing the kind of story that looks outward to space travel, distant worlds, and adventure. Even without a well-documented public life, the continued availability of the novel suggests a writer whose work still sparks enough curiosity to be rediscovered.
Because so few trustworthy biographical details are readily confirmed, the work itself does most of the talking here. For listeners who enjoy forgotten corners of classic speculative fiction, Simmons offers exactly that: a glimpse of an earlier imagination of the future.
