This folder contains correspondence and other documents relating to the technical and commercial development of Edisonâ€™s alkaline storage battery. There are several undated documents in Edison's hand, including a memorandum regarding the promotion of storage batteries for the illumination and ignition of automobiles, along with numerous items bearing his marginalia. Most of the selected documents are by Edisonâ€™s chief engineer Miller Reese Hutchison and pertain to electric vehicles and automobile ignition systems. Some of Hutchisonâ€™s correspondence refers to motion pictures. Additional correspondents include electrical engineer William C. Bauer of Northwestern University and Dean C. Worcester of the American-Philippine Co.
Approximately 50 percent of the documents have been selected, including all of the documents authored by Edison or bearing substantive marginalia by him. The unselected material consists primarily of unsolicited correspondence and documents concerning the production of nickel flake and other manufacturing issues.
A related letter from Miller Reese Hutchison to William H. Meadowcroft regarding the sale of storage batteries to the U.S. Navy can be found in "Secretary" (E-14-78). Courtesy of Thomas Edison National Historical Park.
