Question: In 1949, Canadian news magazine Maclean's was the original publisher of "The Exiles," a science fiction story by which celebrated author?
Context: "Hyperpilosity" is a classic science fiction story by L. Sprague de Camp.  It was first published in the magazine "Astounding Stories" for April, 1938, and first appeared in book form in the de Camp collection "The Wheels of If and Other Science Fiction" (Shasta, 1949; It later appeared in the anthologies "Omnibus of Science Fiction" (Crown, 1952), "Science Fiction of the Thirties" (Bobbs-Merrill, 1975), "The Edward De Bono Science Fiction Collection", (Elmfield Press, 1976) and "" (Mentor, 1979), as well as the magazine "Fantastic Story Magazine" (September, 1953) and the de Camp collection "The Best of L. Sprague de Camp" (Doubleday, 1978).  In 2014 the story was shortlisted for the Retro Hugo Award for Best Short Story. "The Little Black Bag" is a science fiction short story by American Cyril M. Kornbluth, first published in the July 1950 edition of "Astounding Science Fiction".  It is a predecessor of sorts to the story "The Marching Morons".  It won the 2001 Retroactive Hugo Award for Best Novelette (of 1951) and was also recognized as the 13th best all-time short science fiction story in a 1971 "Analog Science Fact & Fiction" poll, tied with "Microcosmic God" by Theodore Sturgeon.  It was among the stories selected in 1970 by the Science Fiction Writers of America as one of the best science fiction short stories published before the creation of the Nebula Awards.  As such, it was published in "The Science Fiction Hall of Fame Volume One, 1929-1964". "The Exiles" is a science fiction short story by Ray Bradbury.  It was originally published as "The Mad Wizards of Mars" in "Maclean's" on September 15, 1949 and was reprinted, in revised form, the following year by "The Magazine of Fantasy & Science Fiction".  First collected in "The Illustrated Man" (1951), it was later included in the collections "R Is for Rocket" (1962), "" (2003), "A Sound of Thunder and Other Stories" (2005) and "A Pleasure to Burn" (2010, under the "Mad Wizards" title and presumably with the "Maclean's" text). "The Runaway Skyscraper" is a science fiction short story by American writer Murray Leinster, first appeared in the February 22, 1919 issue of "Argosy" magazine.  Although Leinster had been appearing regularly in "The Smart Set" and pulp magazines such as "Argosy" and "Short Stories" for three years, "The Runaway Skyscraper" was his first published science fiction story (or more accurately, scientific romance, since Hugo Gernsback had yet to coin the phrase "science fiction").  Gernsback would reprint the story in the third issue of his science fiction pulp magazine "Amazing Stories" in June 1926. The Theodore Sturgeon Memorial Award is an annual award presented by the Center for the Study of Science Fiction at the University of Kansas to the author of the best short science fiction story published in English in the preceding calendar year.  It is the short fiction counterpart of the John W. Campbell Memorial Award for Best Science Fiction Novel, awarded by the same organization.  The award is named in honor of Theodore Sturgeon, one of the leading authors of the Golden Age of Science Fiction from 1939 to 1950.  The award was established in 1987 by his heirs—including his widow, Jayne Sturgeon—and James Gunn, at the time the Director of the Center for the Study of Science Fiction. Maclean's is a Canadian news magazine that was founded in 1905, reporting on Canadian issues such as politics, pop culture, and current events.  Its founder, publisher J. B. Maclean, established the magazine to provide a uniquely Canadian perspective on current affairs and to "entertain but also inspire its readers".  Its publisher since 1994, Rogers Media, announced in September 2016 that "Maclean's" would become a monthly beginning January 2017, while continuing to produce a weekly issue on the Texture app. Sexual assault in the Canadian Forces has been a pervasive issue affecting women, youth, and men in the Canadian Forces and Canadian Cadet Organizations.  Canadian Forces sexual assault cases have been extensively reported in national Canadian news media.  The scope and depth of the sexual assault problem first came to light in 1998, when Maclean's magazine broke the story.  Individual cases continued to be reported.  The issue became a national focus again when MacLean's magazine published another exposé exploring the extent of rape culture in Canada's military. "The Merman" is a science fiction story on the concept of human biological engineering by L. Sprague de Camp.  It was first published in the magazine "Astounding Science-Fiction" for December, 1938.  It first appeared in book form in the collection "The Wheels of If and Other Science Fiction" (Shasta, 1949); it later appeared in the anthology "Science Fiction of the Thirties" (Bobbs-Merrill, 1975) and the collection "The Best of L. Sprague de Camp" (Doubleday, 1978).  The story has been translated into German TBD (Turkish Informatics Association) Science Fiction Story Contest is the only institutionalized contest in the area of science fiction story in Turkey since its foundation in 1998.  The contest specification is posted every April on www.tbd.org.tr or www.bilisimdergisi.org.  The award ceremony is held every autumn during the Information Convention in Ankara, Turkey. There have been many attempts at defining science fiction.  This is a list of definitions that have been offered by authors, editors, critics and fans over the years since science fiction became a genre.  Definitions of related terms such as "science fantasy", "speculative fiction", and "fabulation" are included where they are intended as definitions of aspects of science fiction or because they illuminate related definitions—see e.g. Robert Scholes's definitions of "fabulation" and "structural fabulation" below.  Some definitions of sub-types of science fiction are included, too; for example see David Ketterer's definition of "philosophically-oriented science fiction".  In addition, some definitions are included that define, for example, a science fiction story, rather than science fiction itself, since these also illuminate an underlying definition of science fiction.
