[NP111-F] PN-17-08-29 (1917)

The dated entries in this pocket notebook cover the period August-September 1917. The book was used by Edison for notes pertaining primarily to war-related experiments. Included are experiments on sound detection devices and other means of locating submarines. There are also references to a "kite rudder" that would enable Allied ships to turn more quickly in case of an emergency; Lyle gun projectiles; smokescreens that might enable ships to conceal themselves from enemy submarines; and other camouflaging devices. Much of the research was conducted aboard the yacht Rampant and the Navy warship USS Sachem in Long Island Sound. Also included is a notation regarding a meeting in Washington, D.C., with President Woodrow Wilson on August 20, 1917. Some entries appear to be transcriptions of entries from PN-17-04-27. Among the employees who assisted Edison were Isidor (Jerry) Chesler, John A. Hanley, Absalom M. Kennedy, Benjamin Liebowitz, Sherwood T. (Sam) Moore, and Frederick P. Ott. There are also several references to artist Orlando Rouland, who participated in some of the experiments. The pages are unnumbered. Approximately 160 pages have been used.
