Entitled A Momentous Century - The Glashütte Watch Industry 1845-1945, the first volume constitutes a sociopolitical and historic foundation. It provides an account of the early days of precision horology in Saxony and features biographies of famous watchmakers who worked in Dresden, among them Johann Gottfried Köhler, Johann Heinrich Seyffert, Johann Friedrich Schumann, and Johann Christian Friedrich Gutkaes, Ferdinand A. Lange's apprentice master and mentor. In detail, the author portrays watch manufactories, watchmaking workshops and suppliers, and the German School of Watchmaking in Glashütte. The result is a vivid picture of Saxony's watchmaking industry after the Lange manufactory was established in 1845.The second volume, entitled A. Lange & Söhne - The Watchmakers of Dresden, tells the story of Ferdinand A. Lange's life from his beginnings as a watchmaker in Dresden and the incorporation of the first manufactory to his ingenuity in mechanical design and his dedication to social causes. Tracing the brand's heyday under the auspices of Ferdinand's sons Richard and Emil, Reinhard Meis describes the subsequent expropriation of the manufactory after World War II and its re-establishment as Lange Uhren GmbH by Walter Lange, a member of the founding family's fourth generation. A compendium of current timepieces from the LANGE 1 to the LANGE ZEITWERK forms the conclusion of the second volume and corroborates the role of A. Lange & Söhne as one of the pacemakers of Europe's horological culture in the 21st century
