This folder contains correspondence and other documents relating to the technical development of electric vehicles and automobiles. Also included are items concerning automobiles owned by Edison and his family. Among the correspondents for 1915 are Day Baker of the General Vehicle Co. and former laboratory employees Walter E. Holland and Arthur E. Kennelly.
