This folder contains correspondence and other documents relating to the patenting, manufacture, and sale of Edison storage batteries in Europe. Most of the correspondence is by or addressed to the following individuals: Robert Rafn, who assisted attorneys working to obtain patents in Continental Europe; Herman E. Dick, who was authorized by Edison to exploit the battery commercially throughout Europe; Willis N. Stewart, who was involved briefly with the exploitation of the competing Jungner patents; and Sigmund Bergmann, who began to manufacture Edison storage batteries at his factory in Berlin.
Approximately 50 percent of the documents have been selected. Among the items not selected are account statements from the Bergmann electrical works, a report on the status of Edison's German storage battery patents, and numerous letters from Stewart that contain little substantive information regarding storage batteries in Europe. Some unselected items bear Edison's marginal notes, "Send to Dick" or "file Foreign Storage Battery."
