John Garth (b. 9 June 1966), winner of the 2004 Mythopoeic Society Scholarship Award, studied English at Oxford University and has since worked as a newspaper journalist in London. A long-standing taste for the works of Tolkien, combined with an interest in the First World War, fueled the five years of research that have gone into Tolkien and the Great War and he has drawn extensively on previously unpublished personal papers as well as Tolkien's service record and other unique military documents.
