This folder contains correspondence and other documents relating to the commercial development of Edison's alkaline storage battery in Germany and Austria-Hungary under the auspices of Sigmund Bergmann, head of the failing Deutsche Edison-Akkumulatoren-Co. in Berlin. Most of the correspondence is between Edison and Bergmann. Among the documents for 1912 are letters concerning the proposed sale of Bergmann's battery works and visits to the Berlin works by A. J. Doty of the Edison Storage Battery Co. and John F. Monnot, representative of the Edison company in Great Britain and parts of Europe. Some letters indicate Bergmann's relationship with stockholders, the Deutsche Bank, and competitors such as Allgemeine Elektricitäts-Gesellschaft and Siemens & Halske.

All of the documents have been selected except letters of transmittal, duplicates, and variant versions of selected items.
