One of the great unsung American inventors and timepiece pioneers was this New Jersey watchmaker, who held more than 40 patents but is remembered for the "calculagraph," a device that records times and calculates the difference; one of its first uses was in 1894 in New York, where it recorded the length of telephone calls and impressed AT & T so much they installed it nationwide; his other inventions include a watch winding system that resulted in watches being wound by their stem instead of with a key and a revolutionary method for making enamel watch dials. TNS, 1p, 8½" X 11", New York, NY, 1933 October 16. Addressed to Mary B. Day, librarian at Chicago's Museum of Science and Industry. Near fine. On ornate Calculagraph Company letterhead (featuring at the bottom a faint engraving of the calculagraph machine being used, with its slogan "It Makes No Clerical Errors"), Abbott graciously notes: "It gives me great pleasure to comply with your request and I am sending in the same mail for filing in your library a copy of the pamphlet entitled: 'Watches and Men'." Large, bold signature. Uncommon. Bookseller Inventory # 20938
