Eric Flint was the creator of the New York Times best-selling Ring of Fire series, the best-selling alternate history series of all time. Beginning with 1632, Flint–along with dozens of cowriters–chronicled what happened when the 20th-century town of Grantville, West Virginia, was transported through time and space to 17th-century Europe. In addition, Flint was the author, with New York Times best seller David Weber, of the Crown of Slaves Saga, as well as the Belisarius series with best-selling author David Drake. Flint was the editor of Jim Baen’s Universe, as well as numerous short story anthologies. Before becoming a writer, Flint worked as a trade union organizer, longshoreman, truck driver, auto worker, steel worker, oil worker, meatpacker, glassblower, and machinist. Eric Flint passed away in 2022.
