These letters to Francis Jehl, written in 1937-1938, contain the detailed recollections of Edward E. Winters, a production tester and central station engineer who eventually became chief assistant at the Edison Machine Works (later Edison General Electric) in Schenectady, New York. The reminiscences cover the period from the early or mid-1880s through 1892 and mention many other Edison employees, with particular emphasis on Alfred J. Harksen, John Kruesi, and Montgomery Waddell. The central stations discussed include those installed in Rochester, Detroit, Chicago, Philadelphia, and Columbus, Ohio.
