David H. Keller

David Henry Keller (December 23, 1880 – July 13, 1966) was an American writer who worked for pulp magazines in the mid-twentieth century, in the science fiction, fantasy and horror genres. He was the first psychiatrist to write for the genre, and was most often published as David H. Keller, MD, but also known by the pseudonyms Monk Smith, Matthew Smith, Amy Worth, Henry Cecil, Cecilia Henry, and Jacobus Hubelaire. John Clute has written, "It is clear enough that Keller's conceptual inventiveness, and his cultural gloom, are worth more attention than they have received; it is also clear that he fatally scanted the actual craft of writing, and that therefore he is likely never to be fully appreciated."
