Christopher Anvil was a pseudonym used by author Harry C. Crosby. He began publishing science fiction with the story "Cinderella, Inc." in the December 1952 issue of the science fiction magazine Imagination. By 1956, he had adopted his pseudonym and was being published in Astounding Magazine. Anvil's repeated appearances in Astounding/Analog were due in part to his ability to write to one of Campbell's preferred plots: alien opponents with superior firepower losing out to the superior intelligence or indomitable will of humans. A second factor is his stories are nearly always humorous throughout. Another was his characterization and manner of story crafting, where his protagonists slid from disaster to disaster with the best of intentions, and through exercise of fast thinking, managed to snatch victory somehow from the jaws of defeat.

Joseph John Poyer (born 1939) was an international bestselling thriller novelist in the 1960s, 1970s, and 1980s Poyer has shifted his attention to military-related, non-fiction books under his own publishing company, North Cape Publications.

Also credited as Charles Harness. Charles Leonard Harness was born December 29, 1915 in Colorado City TX. After an abortive stint at Texas Christian University, studying to be a preacher, he moved on to George Washington University in Washington DC, where he received a B.S. degree in 1942, and a law degree in 1946. He married in 1938, and he and wife Nell have a daughter and a son. He worked as a mineral economist for the US Bureau of Mines, 1941-47, then became a patent attorney, first with American Cyanamid (1947-1953), then with W.R. Grace & Co. (1953-1981). His first story, ‘‘Time Trap’’, appeared in Astounding (8/48), and he went on to write a number of well-regarded SF stories, many involving future trials and patent attorneys. A series of patent office spoofs/stories (some co-written with Theodore L. Thomas) appeared under the pseudonym Leonard Lockhard, beginning with ‘‘Improbable Profession’’ (Astounding 9/52). His first published novel, Flight Into Yesterday (aka The Paradox Men), first appeared as a 1949 novella, and was expanded in 1953. The Rose, his most famous novella, appeared as a book in 1966. It was followed by Wagnerian space opera The Ring of Ritornel (1968), Wolfhead (1978), The Catalyst (1980), Firebird (1981), The Venetian Court (1982), Redworld (1986), Krono (1988), Lurid Dreams (1990), and Lunar Justice (1991). His short fiction has been collected in An Ornament to His Profession (1998), which includes not only ‘‘The Rose’’ but a new novella as well.
