[E1171-F] (E-11-71) Phonograph

This folder consists primarily of communications from Edison to members of his technical staff in West Orange and Glen Ridge relating to the development of disc and cylinder phonographs. Included are notes to longtime associate Jonas Walter Aylsworth; machinists Robert A. Bachman and Sherwood T. (Sam) Moore; tool and model maker Alexander N. Pierman; and Albert F. Wurth, head of the department making molds to manufacture duplicate records. Among the documents for 1911 are outlines and reports concerning transfer and pressing processes, the design of labels, and the manufacturing of speakers, along with Edison's ideas for a new veneer transfer process. Also included is a communication by Edison intended for either Albert O. Petit or his brother Ademor N. Petit, laboratory employees who were involved in phonograph development.

All of the documents have been selected.
