Born in Indiana on February 7, 1913, Henry Louis Hasse was an American science fiction writer and fan who became part of the Los Angeles fandom that helped shape the genre in the 1930s and 1940s. He is most often noted today for co-writing "Pendulum," the story generally recognized as Ray Bradbury’s first professional publication, which appeared in Super Science Stories in 1941.
Hasse also wrote a substantial body of his own short fiction for magazines including Weird Tales, Amazing Stories, and Planet Stories. Among his best-known works is "He Who Shrank," a frequently anthologized story built on one of science fiction’s great sense-of-scale ideas. He later published the novel The Stars Will Wait in 1968.
Beyond his fiction, Hasse was remembered as an active and enthusiastic member of science fiction fandom, especially in Los Angeles. That mix of fan energy, magazine-era storytelling, and close ties to other writers gives his career a special place in the history of classic American SF.
