Note 8 — Developing the Invention

Chas. S. Crossman, “A complete history of watch and clock making in America,” Jewelers Circular and Horological Review, January 1888, pp. 400, 401. This history ran as a continuing series of short articles appearing over a period of years. In his sketch of the Waterbury Watch Co., Crossman gives the name as William D. Coates, a name not found in Boyd’s Directory of the District of Columbia for 1875. The directory does, however, contain the name of William D. Colt, a patent attorney.
