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'.
