This early work by Jacques Barzun is both expensive and hard to find in its first edition. It details the history and social influence of Darwin, Marx and Wagner during the nineteenth century. This fascinating work is thoroughly recommended for inclusion on the bookshelf of anyone interested in the influential figures of science, politics and the arts. Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
