These documents cover the years 1880-1924; there are also several undated items. Included is a December 1883 letter from Edison to the renowned Hungarian violinist Ede (Edward) Reményi declining a dinner invitation and remarking that he "must work, work, things are booming." Also included is a 1894 letter from Edison to William S. Pilling, a Philadelphia industrialist who later became secretary-treasurer of the Edison Portland Cement Co., describing production difficulties at the ore milling plant in Ogden, New Jersey. In a 1920 letter to Perriton Maxwell, editor of Leslie's, Edison reminisces about selling that magazine as a newspaper boy on the Grand Trunk Railroad. In addition, there are undated technical notes, probably from 1917-1918, pertaining to wartime experiments involving the use of telephones for sound detection; and a 1924 letter regarding Edison's $300 contribution to a Thomas Paine Memorial Building.
