These documents cover the years 1870-1875, with two additional items from the early 1880s. The documents from the 1870s consist of agreements and patent assignments involving telegraph equipment. Among the parties mentioned are Franklin L. Pope and James N. Ashley, who together with Edison established the firm of Pope, Edison & Co. in 1869. Also mentioned are the American Printing Telegraph Co., Gold and Stock Telegraph Co., and Western Union Telegraph Co. One item from the 1880s is a letter from Henry C. Nicholson, a telegraph inventor involved in the patent interference case, Edison v. Nicholson. The other is a letter from Edison to Albert B. Chandler, president of the Fuller Electrical Co., seeking advice on a prospective construction foreman for his New York central station.
