These documents relate to Percy W. MacKaye, author and dramatist, and his father Steele MacKaye, theatrical designer, actor, dramatist, and inventor. Two undated letters by Edison from the 1880s pertain to his involvement in the lighting of Steele MacKaye's Lyceum Theater in New York. The remaining items, which cover the years 1915 and 1922-1929, are primarily letters to Percy MacKaye from Edison, Mina Miller Edison, and William H. Meadowcroft. Also included is a series of typewritten questions, with responses in Edison's hand, regarding the inventor's relationship with Steele MacKaye.
