Edmond Hamilton came to comics from science fiction pulp magazines, for which he was the creator of grand space operas such as "The Star Kings" and classic short stories like the introspective "What's It Like Out There?" He created Captain Future for pulp editor Mort Weisinger in 1939 and, upon moving to DC Comics in 1941, Weisinger offered Hamilton work on comics scripts. Hamilton quickly became a major Superman writer. In addition, he wrote Tommy Tomorrow features for ACTION COMICS and classic stories for DC editor Julius Schwartz's science fiction comics.

In 1952, Hamilton teamed Superman and Batman in "The Mightiest Team in the World" (SUPERMAN #76), a story he conceived as a minor one-shot adventure. Editor Jack Schiff soon made the Superman-Batman team a regular feature in WORLD'S FINEST, where Hamilton wrote the majority of stories until 1966. In other Batman, Superman, and Legion of Super-Heroes stories, Hamilton introduced such memorable characters as Batwoman, the Composite Superman, Element Lad, and Dream Girl.

Hamilton retired from comics in 1966 and lived with his wife, Leigh Brackett (novelist and screenwriter whose credits include The Big Sleep and The Empire Strikes Back), until his death in 1977.
