This letterbook covers the period September-November 1914. Most of the correspondence is by Edison and William H. Meadowcroft. Included are letters concerning chemical shortages during World War I, Edison's opinion of Jewish bankers and industrialists in Germany, and the feasibility of constructing concrete houses in France and Belgium after the war. Other documents pertain to Edison's property at 10 Fifth Avenue in New York City; demonstrations of the disc phonograph; and commemorations in honor of Edison and electric lighting. The correspondents include Herbert L. Satterlee, a biographer of J.P. Morgan; longtime Edison associate Thomas Commerford Martin; reformer Lillian Wald; and financier Jacob H. Schiff of Kuhn, Loeb and Co.
