Harry Turtledove was born in Los Angeles, California on June 14, 1949. He received a Ph.D. in Byzantine history from UCLA in 1977. From the late 1970's to the early 1980's, he worked as a technical writer for the Los Angeles County Office of Education. He left in 1991 to become full-time writer. His first two novels, Wereblood and Werenight, were published in 1979 under the pseudonym Eric G. Iverson because his editor did not think people would believe that Turtledove was his real name. He used this name until 1985 when he published Herbig-Haro and And So to Bed under his real name. He has received numerous awards including the Homer Award for Short Story for Designated Hitter in 1990, the John Esthen Cook Award for Southern Fiction for Guns of the Southand in 1993, and the Hugo Award for Novella for Down in the Bottomlands in 1994.
