This volume, written by historians and specialists in the history of photography, presents the photographs from the Krupp archives. Krupp was a leader in German steelworks from the nineteenth century onwards. The book explores the business and social history of this worldwide company and presents photography as a source for the history of labor and technology. The lives of the ""Kruppians"" outside the factory gates, and relations between the town of Essen and the Krupp factories vividly illustrate the development of industrialism in Europe.
