This notebook was used by Absalom M. Kennedy during January-February 1914 as a record of experimental work on the kinetophone. There are a few additional entries from December 1914 and January 1915. Included are experiments on frictional reproduction, motor regulation, and synchronous motors. The entries describe comparison tests between various brands of equipment, as well as inspections of records and reels for foreign orders. Also included are tests on kinetoscope shutters and film cement. At the end of the book is a list of ideas for improving the kinetoscope. The notes indicate that Kennedy received instructions directly from Edison on the work to be performed, along with comments and suggestions. There are also indications that John W. Farrell, Adolph F. Gall, Daniel Higham, and Charles W. Luhr were involved in similar work. The front cover is labeled "Jobs Undertaken. Jan. 1, 1914. & Kinetoscopes Ideas." The book contains 200 numbered pages and an index; many pages are blank. Courtesy of Thomas Edison National Historical Park.
