Daniel F. Galouye was an American science fiction writer known for his imaginative storytelling and exploration of deep philosophical and technological themes.
Daniel Francis Galouye was born in New Orleans, Louisiana. He studied at Louisiana State University before serving as a Navy test pilot and instructor during World War II. His military service left him with health problems that would later contribute to his early retirement and eventual death. After the war, he worked as a journalist and editor for The States-Item, a New Orleans newspaper, while developing his career as a science fiction writer.
Galouye's fiction often explored psychological manipulation, alternate realities, and the nature of perception. His most famous work, Simulacron-3 (1964), was a groundbreaking novel about simulated realities and artificial intelligence.
The novel anticipated themes later seen in films such as The Matrix and inspired adaptations such as the German miniseries World on a Wire (1973) and the Hollywood film The Thirteenth Floor (1999). Another of his notable works, Dark Universe (1961), presented a post-apocalyptic society that had adapted to living in total darkness and explored how sensory perception shapes human understanding of reality. It was nominated for the Hugo Award.
Throughout the 1950s and 1960s, Galouye was a prolific contributor to prominent science fiction magazines such as Galaxy Science Fiction, Fantastic Universe, and The Magazine of Fantasy & Science Fiction. Writing under his name and the pseudonym Louis G. Daniels, he published numerous short stories and novellas, many of which were later collected in anthologies such as The Last Leap and Other Stories of the Supermind (1964) and Project Barrier (1968).
His work often explored themes of telepathy, mind control and the limits of human consciousness, as in Lords of the Psychon (1963) and A Scourge of Screamers (1968).
Despite his literary achievements, Galouye's career was cut short by failing health, which forced his early retirement in 1967.
He spent his later years between his home in New Orleans and a retreat in Covington, Louisiana, before passing away at the age of 56.
In 2007, his contributions to science fiction were posthumously recognised with the Cordwainer Smith Rediscovery Award, which honors overlooked but influential genre writers.
