Henry Hasse

Born in Indiana on February 7, 1913, Henry Louis Hasse became part of the energetic world of American science fiction as both a writer and an active fan. He is best known for co-writing "Pendulum", the story that became Ray Bradbury's first professionally published fiction, and he later collaborated with Bradbury on other stories as well.

Hasse published fiction in the great pulp-magazine era, writing short stories and novellas that blended big speculative ideas with a fast, entertaining style. Among the works often remembered are "He Who Shrank" and the novel The Stars Will Wait, and his reputation has lasted through science-fiction reference works and reprints of his shorter fiction.

He died in Los Angeles, California, on May 20, 1977. Though not as famous as some of his contemporaries, he remains an appealing figure for readers interested in the roots of modern science fiction and the close-knit fan-and-writer communities that helped shape the genre.
