Everything about John D Clark totally explained
John Drury Clark, Ph.D. (
August 15,
1907-July
1988) was a noted
American rocket fuel developer,
chemist, and
science fiction writer and fan. He was instrumental in the revival of interest in
Robert E. Howard's Conan stories and influenced the writing careers of
L. Sprague de Camp,
Fletcher Pratt, and other authors.
Life and career
Clark was born in
Alaska. He attended the
University of Alaska, and then received a B.S. at the
California Institute of Technology at
Pasadena,
California in the 1920s, where he was the college roommate of
L. Sprague de Camp. He received an M.S. from the
University of Wisconsin-Madison, and, in 1934, a PhD from
Stanford University. He moved to upstate
New York in the early 1930s. He married in 1944.
From 1949, until his retirement in 1970, Clark developed liquid propellants at the Naval Air Rocket Test Station at
Dover,
New Jersey (after 1960, this became the Liquid Rocket Propulsion Laboratory of Picatinny Arsenal). His title there was chief chemist. He was the author of
Ignition! An Informal History of Liquid Rocket Propellants (1972).
In his later years Clark lived in
Newfoundland,
Passaic County, New Jersey. He died in July, 1988. His papers, consisting of four cubic feet of correspondence, drafts of scientific and science fiction publications, notes, an unpublished typescript memoir, diaries (1923-1984), clippings, and photos, are preserved in the Special Collections at
Virginia Tech as part of that repository's Archives of American Aerospace Exploration.
Literary career and influence
As a fan of the science fiction and fantasy magazines of the
pulp era, Clark became friendly with several figures who were or would become authors in both fields, including
P. Schuyler Miller,
Fletcher Pratt, and
L. Ron Hubbard.
Clark and Conan
Clark first encountered
Robert E. Howard's fantasies of
Kull,
Conan and
Solomon Kane in the magazine
Weird Tales. Together with Miller he worked out an outline of Conan's career and a map of the world in Howard's invented
Hyborian Age in early 1936 from the then-published stories. Miller sent this material to Howard, whose reply confirmed and corrected their findings. Their revised outline, "A Probable Outline of Conan's Career," was published in the
fanzine The Hyborian Age in 1938.
Thus established as an authority on Conan, Clark was invited to provide introductions for the first book editions of Howard's Conan stories, published by
Gnome Press in the 1950s. Expanded versions of his and Miller's essay on Conan, retitled "An Informal Biography of Conan the Cimmerian," appeared in the Gnome volume
The Coming of Conan in 1953 and (revised by de Camp) in the fanzine
Amra, vol. 2, no. 4, in 1959. It was the source of the linking passages between the individual Conan stories in both the Gnome editions and the
Lancer paperback editions of the 1960s.
Clark and Miller's Hyborian Age map, together with Howard's own original, are the basis of those published in the Gnome, Lancer, and later editions of the stories.
Clark and the science fiction community
While unemployed in the mid-1930s Clark wrote a couple of science fiction stories, with plotting assistance from L. Sprague de Camp, which were published in
Astounding Stories in 1937. While he himself wrote no more science fiction, this experience prompted de Camp to launch his own career as a science fiction writer, first with short stories and then with a novel in collaboration with their mutual friend Miller.
Clark furthered de Camp's career in another way by introducing him into Fletcher Pratt's war-gaming circle, and to Pratt himself, in 1939. De Camp and Pratt went on write some of the most celebrated light fantasy of the 1940s, the
Harold Shea and
Gavagan's Bar stories.
Clark also provided L. Ron Hubbard with the germ for his humorous fantasy novella
The Case of the Friendly Corpse, published in the August 1941 issue of
Unknown. According to de Camp, in the 1930s Clark and a friend named Mark Baldwin had "concocted a prospectus for an imaginary College of the Unholy Names" in the 1930s, which Clark lent to Hubbard in 1941. Hubbard then built his story around the setting.
Clark's marriage in
1944 led to the establishment of the all-male literary banqueting club the
Trap Door Spiders, founded in that year by Pratt. As the new Mrs. Clark was reportedly unpopular with Pratt and others of his friends, the club gave them an excuse to spend time with him without her. The Trap Door Spiders later served as the model for
Isaac Asimov's fictional group of mystery solvers the
Black Widowers. Clark himself was fictionalized as the James Drake character.
In 1952 Clark provided the scenario for the Twayne Science Fiction Triplet
The Petrified Planet, postulating a world whose description was then used as the basis for the three novellas by Pratt,
H. Beam Piper and
Judith Merril forming the body of the work. An excerpt from Clark's introduction ("The Silicone World") was reissued in the December, 1952 issue of
Startling Stories, and the whole was reprinted in the 1983
Ace edition of Piper's contribution to the book,
Uller Uprising. The
Startling Stories excerpt has also been credited to Pratt, who supposedly utilized Clark's name as a
pseudonym.
