Henry Louis Hasse was an American science fiction writer and fan, born on February 7, 1913, in Indiana and active for decades in the Los Angeles fan and publishing scene. He published early fiction in the 1930s and was part of the close-knit world of magazine-era science fiction, where writers, editors, and fans often overlapped.
He is most often remembered today for co-authoring Ray Bradbury’s first professionally published story, Pendulum, which appeared in Super Science Stories in November 1941. Hasse also worked with other writers, including A. Fedor and Emil Petaja, and wrote under names such as Henry L. Hasse and Theodore Pine.
Among his best-known solo pieces is the novelette He Who Shrank, a clever and memorable story that continued to attract readers through later anthologies. He died on May 20, 1977, but his reputation has lasted through science fiction reference works, fan histories, and the enduring interest in pulp-era speculative fiction.
