This folder contains correspondence and other documents relating to the technical and commercial development of talking pictures. Included are items pertaining to the experimental work contracted to Daniel Higham for a combined phonograph-projector. Other documents relate to Edison's concern about an appropriate name for Higham's "talking picture machine" (eventually called the "kinetophone") and to the evaluation of improvements submitted by outsiders. Among the correspondents are Frank L. Dyer, vice president of the Edison Manufacturing Co.; George F. Scull, assistant to the vice president; and employee Isaac W. Walker.

Approximately 70 percent of the documents have been selected. The items not selected include correspondence regarding improvements that the Edison Manufacturing Co. declined to pursue, as well as items that duplicate information in selected material.
