Henry Kuttner was a prolific science fiction and horror author. His first story was published in 1936, and from there he wrote, under a set of pen names, a large number of short stories, novels, and comic strips, up until his early death in 1958. A lot of his work was penned in collaboration with his wife C. L. Moore, but she was only sometimes directly credited.

Kuttner was a friend of H. P. Lovecraft —he wrote a set of stories specifically set in the Cthulhu mythos—and while he was primarily a science fiction writer, there is a streak of Lovecraftian darkness running through the majority of his work. Even in his most optimistic tales, the characters often end up with more problems than they bargained for—or at least finish feeling no happier than before.
