Henry Kuttner (April 7, 1915 – February 4, 1958) was an American author of science fiction, fantasy and horror.
A friend of Lovecraft's as well as of Clark Ashton Smith, Kuttner contributed several stories to the Cthulhu Mythos genre invented by those authors (among others). Among these were "The Secret of Kralitz" (Weird Tales, October 1936), "The Eater of Souls" (Weird Tales, January 1937), "The Salem Horror" (Weird Tales, May 1937), "The Invaders" (Strange Stories, February 1939) and "The Hunt" (Strange Stories, June 1939).
Kuttner added a few lesser-known deities to the Mythos, including Iod ("The Secret of Kralitz"), Vorvadoss ("The Eater of Souls"), and Nyogtha ("The Salem Horror"). Critic Shawn Ramsey suggests that Abigail Prinn, the villain of "The Salem Horror", might have been intended by Kuttner to be a descendant of Ludvig Prinn, author of De Vermis Mysteriis—a book that appears in Kuttner's "The Invaders".
Crypt of Cthulhu 5, No 7 (whole number 41) (Lammas 1986), edited by Robert M. Price, was a special Henry Kuttner issue collecting eight Cthulhu Mythos stories by Kuttner. (It did not include "Spawn of Dagon" or "The Invaders").
The Book of Iod: Ten Tales of the Mythos is a collection of Kuttner's Cthulhu Mythos stories edited by Robert M. Price (Chaosium, 1995). (It also contains three additional tales concerning 'Iod's dread tome' by Robert Bloch, Lin Carter and Robert M. Price). The Kuttner stories included are: "The Secret of Kralitz", "The Eater of Souls", "The Salem Horror", "The Jest of Droom-Avesta", "Spawn of Dagon", "The Invaders", "The Frog", "Hydra", "Bells of Horror" and "The Hunt" - thus, all the Mythos stories which had appeared in the special Kuttner issue of Crypt of Cthulhu, plus "Spawn of Dagon" and "The Invaders". The story "The Black Kiss" (printed here, as often elsewhere, under the joint byline of Kuttner and Robert Bloch), was in fact written entirely by Bloch; Bloch co-credited Kuttner on the tale due to using the character Michael Leigh from "The Salem Horror". "Beneath the Tombstone" by Robert M. Price and "Dead of Night" by Lin Carter round out the volume. Price points out in his introduction to the volume that "Henry Kuttner's own private corner of the Cthulhu Mythos was, then, apparently derived in about equal measure from Lovecraft, Bloch, Zoroastrianism, and Theosophy."
