This folder contains correspondence, technical notes, and other documents relating to Edison's experimental projects conducted for the U.S. Navy during World War I, including work that took place at Key West, Florida. Included are telegrams about Edison's need for equipment and supplies, along with communications with members of his experimental staff such as Charles B. Hanford, Samuel C. Shaffner, and Selden G. Warner. Also included are letters from Col. J. W. Fuller of the Fuller Engineering Co. regarding the use of pulverized coal; a copy of a 1916 letter by deceased Edison chemist Jonas Walter Aylsworth suggesting that chlorine gas could be used to stop zeppelin engines; and a log by experimenter John A. Hanley of acoustic observations of submarine noise at the Naval Experimental Station in New London, Connecticut. At the end of the folder are several pages of undated technical notes and drawings by Edison and William H. Knierim on the use of audion tubes for underwater sound detection.
Approximately 60 percent of the documents have been selected. The unselected material relates to routine orders and shipping instructions and payments.
