[D9437-F] (D-94-37) Telegraph

This folder contains correspondence relating to the technical and commercial development of the telegraph. Many of the letters are by Josiah C. Reiff and pertain to Edison's 1877 contract with Western Union and to the litigation between that company and the Atlantic & Pacific Telegraph Co. over Edison's quadruplex patents. There are also letters from Jerome Carty, a patent attorney, about the automatic telegraph patents of Edison and Patrick Kenny and one item containing a comment by Edison about phonoplex telegraphy.

All of the documents have been selected.
