author
A mid-century science fiction writer whose work captures the fast-moving, adventurous spirit of the pulp era. Best known for the novel-length tale Z-Day on Centauri, he wrote the kind of planetary adventure that helped define magazine science fiction in the 1940s.

by Henry T. Simmons
Very little biographical information could be confirmed about Henry T. Simmons from reliable online sources consulted here. What is clear is that he was a science fiction author associated with the pulp-magazine era, and that his best-known work is Z-Day on Centauri.
That story appeared in Planet Stories in Summer 1948 as a novel-length adventure, and it has since remained accessible through Project Gutenberg and other archival science fiction resources. The book follows a space pilot drawn into conflict on Centauri V, giving modern readers a good snapshot of the energetic, action-first style that made pulp science fiction so popular.
Because solid personal details were not readily available, the work itself is the best introduction to Simmons. For listeners who enjoy vintage space opera, his fiction offers a direct line back to the imagination and optimism of postwar magazine science fiction.
