Utley was born in the family of an Air Forcenon-commissioned officer and grew up on Air Force bases in the United States, Great Britain, and Okinawa. During the 1970s, he joined a group of science fiction writers in Austin, Texas, which included Lisa Tuttle, Howard Waldrop, and Bruce Sterling; the group was later formalized as Turkey City Writer's Workshop. Utley's first professionally published story, "The Unkindest Cut of All," a parody of Hugo Gernsbackian scientifiction, appeared in 1972. Since then he has published widely in and out of the science-fiction field, and his work has been translated into a dozen languages. The Encyclopedia of Science Fiction calls him "a figure of edgy salience," and Gardner Dozois, who as editor of Asimov's Science Fiction published most of Utley's output during the 1990s, has suggested that he "may be the most under-rated science fiction writer alive," calling him a writer "of strength, suppleness, and seemingly endless resource... able to turn his hand to almost any subject matter, mood, or type of story imaginable, and... unafraid to tackle any of them." The Turkey City writers collaborated prolifically among themselves during the 1970s, and Utley and Waldrop produced two oft-reprinted stories, "Custer's Last Jump" and "Black as the Pit, From Pole to Pole", regarded as prototypes of steampunk science fiction. These appear in Custer's Last Jump! and Other Collaborations along with Waldrop stories co-written by Leigh Kennedy, Bruce Sterling, Al Jackson, Jake Saunders, and George R. R. Martin. Three collaborations with Lisa Tuttle, including "Flies by Night", another story frequently reprinted and translated, appear in Utley's 2005 collection, The Beasts of Love, for which Tuttle provided an introduction. Utley may be best known for his "Silurian Tales," launched in Asimov's Science Fiction in 1993 and continued in not only that magazine but also The Magazine of Fantasy and Science Fiction, Analog Science Fiction and Fact, and the webzinesSci Fiction and Revolution Science Fiction. Described by Brian Stableford in Science Fact and Science Fiction: An Encyclopedia as "he most elaborate reconstruction of a past era in recent speculative fiction," the series employs a variety of literary techniques in recounting the adventures and misadventures of a scientific expedition in the Paleozoic Era and also addresses some implications of the "many-worlds" hypothesis in quantum physics; several of the stories have been reprinted in Gardner Dozois' Year's Best Science Fiction anthologies and the competing Year's Best SF edited by David G. Hartwell and Kathryn Cramer. Ticonderoga Publications, based in Australia, released the Silurian Tales in two volumes titled The 400-Million-Year Itch and Invisible Kingdoms. A separate series of time-travel stories, launched in Galaxy in 1976 but developed extensively in Asimov's Science Fiction during the 1990s, deals with so-called "chronopaths" and has been collected in book form under the title Where or When. Since 1997, Utley made his home in Tennessee, but referred to himself as "an internationally unknown author." Utley was diagnosed with stage four cancer in early December 2012, fell into a coma on January 11, 2013, and died the following night.
