Marc Bloch (blôk), 1886–1944, French historian and an authority on medieval feudalism. He taught at the Univ. of Strasbourg from 1919, became professor at the Sorbonne in 1936, and was cofounder of the journal Annales. Bloch did much to promote the study of economic history. As a Jew, he was subject to German restrictions during World War II. He joined the French Resistance in Lyon in 1942, helping to publish the newspaper Franc-Tireur, a name adopted by the Resistance forces in the region. His activities led to his execution by the Germans. His Strange Defeat (tr. 1949) describes wartime France. Among Bloch's major works are The Historian's Craft (tr. 1953) and French Rural History (tr. 1966). His Feudal Society (tr. 1961) is a brilliant synthesis of the subject.
