This letterbook covers the period November 1913-February 1914. Most of the correspondence is by Edison and William H. Meadowcroft. Included are letters addressed to telephone and utilities executive Theodore N. Vail and to automobile manufacturer Henry Ford. Several documents concern the commercial and technical development of Edison’s alkaline storage battery in the United States and Europe. There are also letters pertaining to public demonstrations of Edison’s disc phonograph and to technical developments related to the kinetophone, Edison’s system for talking motion pictures. Additional correspondence relates to Edison’s health, book acquisitions, and vacations with his family; visitors to the West Orange laboratory; and the disposal of land in Ogden, New Jersey, formerly used by the New Jersey and Pennsylvania Concentrating Works.
