These six notebooks were used by Leroy E. Briggs during 1913-1914. They provide daily logs of Briggs’s work with the home projecting kinetoscope, film developing equipment, and other projects relating to motion pictures. There are also entries on other experiments including a miners’ lamp, locomotive headlights, a new lamp house, an automobile electric self-starter, and a frictional microphone. Miller Reese Hutchison directed some of this work, and Briggs produced weekly reports for him. Other employees who are identified as being involved in related projects include Ernest J. Berggren, William Walter Dinwiddie, Adolph F. Gall, Zachariah P. Halpin, L. E. Hammond, Absalom M. Kennedy, Charles W. Luhr, William H. Meadowcroft, Henry J. S. Rudolf, and Carl H. Wilson.
The two books with indications of oversight by Edison have been selected.
