This undated reminiscence, probably written in 1908, was published in the official two-volume biography, Edison: His Life and Inventions (New York: Harper & Brothers, 1910). Delany, who was associated with the Automatic Telegraph Co., worked with Edison and Edward H. Johnson in 1872 to improve high-speed and multiple telegraph signaling. He retained an acquaintance with Edison for several years afterward.
