This folder contains correspondence and other documents relating to the patenting, manufacture, and marketing of Edison storage batteries in Germany. Most of the items are letters and telegrams exchanged by Edison and Sigmund Bergmann, a longtime Edison associate who, with the backing of the Deutsche Bank, formed the Deutsche Edison-Accumulatoren-Co. in 1904. Included are letters pertaining to blueprints, machine tools, electrolyte, patents, cobalt ores, battery cans, and other battery parts.
Approximately 60 percent of the documents have been selected. The items not selected include routine letters by Philip H. Klein, Jr., an agent of Sigmund Bergmann, and items that duplicate information in selected material.
