This folder contains correspondence and other documents concerning legal cases involving Edison or companies in which he had an interest. The documents for 1915 consist primarily of correspondence requesting evidence from Edison in the cases of United States v. Cardwell and others and American Graphophone Co. v. American Parlograph Corp., as well as in an Australian suit involving electric streetcar manufacturer Ralph H. Beach. Also included are drafts of letters by Edison responding to the attorneys and providing his reasons for not complying with some of the requests.
Approximately 70 percent of the documents have been selected. The unselected material includes several items that relate to the selected cases but do not contain substantial new information. Courtesy of Thomas Edison National Historical Park.
