“Bronterre O’Brien, the ‘schoolmaster of Chartism,’ was the intellectual, inspiring, irascible, and infuriating godfather of the early working-class movement in Britain. In his major biography, the first to be based upon full records and modern historiography, Michael J. Turner reevaluates this major figure and decisively confirms his importance. Highly readable and comprehensively informed, this is a book no student of nineteenth-century British social and political history can afford to ignore.”—Marc Mulholland, Professor of History, Oxford University, author of Bourgeois Liberty and the Politics of Fear: from Absolutism to Neo-Conservatism
