Don Wilcox was a science fiction writer active during the mid-twentieth century. He is best remembered for his seminal short story, "The Voyage That Lasted 600 Years," which was first published in the October 1940 issue of the pulp magazine Amazing Stories.
Wilcox's landmark story is widely credited as the first work of fiction to introduce and explore the concept of a generation starship—a hypothetical spacecraft designed for long-term interstellar travel where the original crew's descendants are the ones who eventually reach the destination. Through this narrative, Wilcox made a foundational contribution to the science fiction genre, establishing a trope that would be revisited by numerous authors in the decades to follow.
Though his broader biographical details remain sparse in historical overviews of the era, his contribution to speculative fiction remains highly regarded by historians of the genre. By introducing the generational ship concept, Wilcox provided a framework for exploring the sociological and psychological impacts of multi-generational space travel, securing his legacy in early science fiction history.
