H.G. Wells was a professional writer and journalist, who published more than a hundred books, including novels, histories, essays and programmes for world regeneration. Wells's prophetic imagination was first displayed in pioneering works of science fiction, but later he became an apostle of socialism, science and progress. His controversial views on sexual equality and the shape of a truly developed nation remain directly relevant to our world today. He was, in Bertrand Russell's words, 'an important liberator of thought and action'. Jay Winter is Professor of History at Yale University. He was previously Reader in History at the University of Cambridge and a Fellow of Pembroke College. He is a specialist on the First World War, and one of the founders of the Historial de la grande guerre at Peronne, Somme, an international museum of the Great War. Patrick Parrinder has written on H.G. Wells, science fiction, James Joyce and the history of the English novel. Since 1986 he has been Professor of English at the University of Reading. Andy Sawyer is a Librarian at the University of Sheffield with a particular interest in science fiction.
