[NP107-F] PN-16-11-15.2 (1916-1917)

The dated entries in this pocket notebook cover the period November 1916-February 1917. The book was used by Edison to record ideas about business matters, experiments to be tried, and other tasks to be performed. Some of the items have been crossed out and marked "Ent." Included are notes on chemical experiments, batteries, photochemistry, the sending of photographs by telephone, disc record composition, and the crushing of diamonds used in disc records. Also included are notes on military topics such as trench warfare, ship detection through acoustic range finding, luminous paint for ships, submarine and torpedo detection, and the prevention of saltwater corrosion of guns on military ships. In addition, there are entries regarding consultants and experts whom Edison wanted for war-related work.

The entries at the beginning of the book appear to be transcriptions of entries from PN-16-11-15.1. The last page contains a notation concerning Edison's agreement of July 22, 1915, with H. H. Meno Kammerhoff, supervisor of operations at his chemical plants in Silver Lake. Other Edison employees mentioned in the book are William Walter Dinwiddie and Sherwood T. (Sam) Moore, principal assistants in the development of disc records; chief engineer Miller Reese Hutchison; and Walter H. Miller, head of the Recording Dept. The pages are unnumbered. Approximately 150 pages have been used.
