1. Lewis H. Latimer, 1911 logbook, page "March 17." [Recollections in Latimer’s own hand are in the collection of Dr. Winifred Latimer Norman, currently held at the Queens Borough Public Library, Queens, NY: They are written in yearbooks dated 1911 and 1912, with dates preprinted on the pages. Latimer first used these books as work logs, then later for drafts of poems and prose. Other biographical and autobiographical sketches—some signed or initialed by Latimer—are typewritten and may be found in the collections at the Queens Borough Public Library; the Edison National Historic Site, West Orange, NJ; and the Henry Ford Library and Archives at Greenfield Village, MI]

4. L. Latimer, 1911 logbook, pages "November 18," "November 17," Norman Collection. In this case Latimer had turned the book upside down and backwards for the purpose of using blank space: Text therefore proceeds from pages with later dates to those with earlier ones.

Maxim had been elected to membership 3 November 1879; Latimer on 13 March 1880. Latimer’s paper was delivered 18 May 1880.

17. For the U.S. Electric Lighting Co., see Harold C. Passer, The Electrical Manufacturers, 1875-1900 (New York: Arno Press, 1972). In an affidavit dated April 4, 1893, Latimer stated "I commenced to work at 120 Broadway [the address after the company moved from Bridgeport] as draughtsman but later on alternated with Joseph E. Lockwood in making carbons, and finally took this part of the work entirely and continued to make carbons until November 1881 when I left the employ of this company," [emphasis added], Norman Collection. It would seem that Latimer’s work in London was under the official auspices of a company other than U.S. Electric Lighting: He may have expected to return to U.S. Electric Lighting afterwards.
