Featuring over 1,000 alphabetically arranged, biographical entries, *Who's Who in World War One* builds up a complete and vivid picture of the major figures of the Great War. The subjects are drawn not only from the political and military spheres of all thirty-two nations involved, but also from the social and cultural life of the period. This book's breadth of coverage makes it the definitive biographical guide to the First World War; from the British air ace, Albert Ball, to the German foreign secretary, Richard von Kuhlmann from David Lloyd George to Rasputin from the British war poet Siegfried Sassoon to the Serbian assassin Trifko Grabez and the Emperor Wilhelm II. Each entry provides biographical data and basic factual information about its subject's role in the Great War, and in the case of major figures there is also an assessment of their reputation in the light of current scholarship. Maps, cross-referencing, a list of military ranks, a guide to further reading and a thorough introduction complete what is at once a comprehensive work of reference and a fascinating overview of a crucial period in twentieth century.
