The Thomas A. Edison Papers Digital Edition

This folder contains correspondence relating to war research conducted at an experimental laboratory of the American Potash Corp. at Jones Point on the lower Hudson River. In addition to Edison and his assistant, William H. Meadowcroft, the main correspondent is Richmond Levering of the U.S. Bureau of Investigation. Included are items dealing with Edison's ideas for measuring the height of seaplanes over water and with the compensation of employee Bruce R. Silver, who was working with Walter T. Scheele at Jones Point on incendiary devices. One report by Silver has been selected as a representative sample.

Approximately 10 percent of the documents have been selected. The items not selected include additional reports by Silver and by Capt. Paul Brinton of the U.S. Army Ordnance Corps, which were sent to Edison by Levering.
