Stephen A. Kallis

Born in New York City in 1937, Stephen A. Kallis, Jr. was an American writer whose published work ranged from science fiction to nonfiction on media and aviation. His short story The Untouchable appeared in the early 1960s and later circulated widely in public-domain and reprint editions, helping keep his name alive with classic SF readers.

Outside fiction, he wrote Radio’s Captain Midnight: The Wartime Biography and was described by his publisher as a licensed pilot who contributed to publications including General Aviation News, Cryptologia, and Popular Mechanics. He was also noted as a member of the Society of Motion Picture and Television Engineers, which fits the technical interests that show up across his writing.

Later biographical notes describe him as living in Tampa, Florida, and as someone whose career and interests stretched well beyond books alone. Taken together, the available sources show a versatile author drawn to science, technology, and twentieth-century popular culture.
