"Monochrome" is a collection of monographs depicting inventors at key moments in their lives. Here we meet historical figures and have the chance to observe them up close, as well as witness their work and its effects. We find out who really invented the cinematograph and who was behind the invention of X-rays, and the mystery behind the discovery of the North Pole will be resolved. This volume also reveals the darker side of life in a world of revolutions, and leaves us uncertain as to whether people control machines, or the other way around.
