Battery Supplies Company

This company was organized in 1903 by former Edison employees James W. Gladstone and Eben G. Dodge to manufacture and sell primary batteries. Edison began litigation in July, alleging patent infringement, and a settlement agreement was signed in November 1904. The company was purchased by the Edison Manufacturing Company in 1905 and officially dissolved in 1908, although its accounts show continued activity through mid-1911.

Deutsche Edison Akkumulatoren Company

Sometimes known as the Deutsche Edison Accumulatoren Company, this company was organized in Berlin between October 1904 and March 1905 to exploit Edison's storage battery in Germany, Austria, and Hungary. Financial backing was provided by the Deutsche Bank.

Edison Gesellschaft

This German company began operating in Berlin on April 1, 1904. It succeeded the National Phonograph Company, Berlin, an unincorporated business, and it sold phonographs, kinetoscopes and films, primary batteries, numbering machines, and other Edison products. Thomas Graf served as manager until November 1, 1915. The company ceased operations shortly after the onset of World War I, although it continued to maintain a small office until Graf's resignation. It was legally dissolved on April 12, 1926.

Edison Manufacturing Company

This company was organized in December 1889 as Edison's personal business and was incorporated in New Jersey on May 5, 1900. Originally formed to manufacture and market the Edison-Lalande primary battery, the company manufactured and sold batteries for use with telegraph, phonoplex, and telephone systems, as well as for phonographs, dental equipment, medical instruments, and other machinery. It also produced kinetoscope films, kinetoscopes, wax for phonograph cylinders, x-ray equipment, medical instruments, and electric fans. The company had a factory at Silver Lake (later named Bloomfield), New Jersey, a sales office in New York City, and agencies abroad. In 1905 its motion picture operations were moved from Manhattan to a studio in the Bronx. The company's assets and property rights were assigned to Thomas A. Edison, Inc., in February 1911. It was dissolved on November 9, 1926.
