[NA350-F] N-15-03-17 (1915)

This notebook is a continuation of N-14-09-21. It was used by Absalom M. Kennedy during March-June 1915 as a daily record of experiments and tests with phonograph recorders and reproducers. The daily record is continued in N-15-06-04.2. The tests involve various instruments and parts of the recording machines and variations in the positions of voices, instruments, and recording horns. Also included are tests of machines to reproduce cylinder records from disc master recordings. The entries also describe other work by Kennedy, including his collaboration with Leonard W. McChesney and other employees in the production of "The Birth of the Telephone," a kinetophone film about Alexander Graham Bell. Kennedy's notes often mention Edison's own involvement in the phonograph experiments, including his comments, suggestions, and further instructions about particular recordings or masters. Other individuals involved in the work include Clarence B. Hayes, Walter H. Miller, John F. Ott, and an experimenter named Taylor (probably Henry A. Taylor). The front cover is labeled "Recording Experiments Book #2 from March 17-1915 to June 4, 1915" in ink and "Kennedy" in pencil. The pages are unnumbered. Approximately 150 pages have been used.
