This folder contains correspondence and other documents relating to the widely publicized development of Edison's poured concrete house. Most of the selected items concern the application of Edisonâ€™s concept by housing developer Frank D. Lambie. Included is a brochure by the Lambie Steel Form Co. containing testimonials by Edison and by Robert A. Bachman of the Edison Storage Battery Co. Also included is a letter from railroad builder Arthur E. Stilwell.
Approximately 10 percent of the documents have been selected. The unselected material consists primarily of unsolicited correspondence that received a perfunctory response or no reply from Edison. Courtesy of Thomas Edison National Historical Park.
