David H. (David Henry) Keller

Born in Philadelphia in 1880, David H. Keller was an American physician and psychiatrist who became one of the notable names in early pulp science fiction. He often published as David H. Keller, M.D., and his medical background gave his fiction an unusual angle for its time.

Keller wrote prolifically for the pulp magazines of the 1920s and 1930s, especially in science fiction, fantasy, and horror. He is often remembered as the first psychiatrist to make a significant mark in the genre, and readers have long noted how often his stories reflect his interest in psychology and mental strain.

He died in 1966 in Pennsylvania, leaving behind a body of work that captures an important stage in the development of American speculative fiction. For listeners exploring early genre writing, his work offers a glimpse of science fiction before it fully settled into its modern form.
