Carl Erdmann

Carl Erdmann (17 November 1898 – 5 March 1945) was a German historian who specialized in medieval political and intellectual history. He is noted in particular for his study of the origins of the idea of crusading in medieval Latin Christendom, as well as his work on letter collections and correspondence among secular and ecclesiastical elites in the eleventh century. He is often mentioned alongside Percy Ernst Schramm and Ernst H. Kantorowicz as one of the most influential and important German scholars of medieval political culture in the twentieth century. His promising and remarkably prolific career was cut short by his death in the German army at the end of World War II. Provided by Wikipedia
