This folder contains correspondence and other documents relating to Edison's past and present friends, acquaintances, and associates. Among the items for 1917 are letters concerning the financial problems, illness, and death of Edison's friend and former business partner Edward H. Johnson. A letter from naturalist John Burroughs introduces war projects researcher Bruce R. Silver to Edison, while several letters from rubber manufacturer Harvey S. Firestone pertain to the souvenir book, In Nature's Laboratory, which documented the 1916 camping trip involving Edison, Firestone, and Burroughs. There is also discussion of another camping trip with Firestone and Henry Ford, which Edison initially agreed to but ultimately declined because of government work "I cannot possibly evade." A communication from newspaper editor Arthur W. Brisbane addressed to Mr. and Mrs. Edison at the Hotel Powhatan in Washington, D.C., invites them to a luncheon featuring a talk by Ford on the nationalization of the railroads. In addition, there are letters regarding a commission in the U.S. Signal Corps for Edison's telegraph industry friend Charles P. Bruch, as well as a New York City apartment rental for his Llewellyn Park neighbor, soap executive Richard M. Colgate. Other correspondents include longtime friend and associate Samuel Insull and British business associate Baron John W. E. Montagu.

Approximately 80 percent of the documents have been selected. The unselected material consists primarily of letters that did not receive a reply from Edison, along with items that duplicate the information in the selected documents.
