<br/><br/> "The Sangamo Electric Co. manufactured  electrical meters, time switches and sonar and radio equipment, among other items, in Springfield from the 1890s until 1978. Sangamo was an offshoot of the Illinois Watch Co., and its Springfield facility generally was the watch company's former factory, which took up four square blocks between Ninth and 11th streets and North Grand and Converse avenues. Sangamo rented space in the watch factory for about two decades, but with the watch business declining and Sangamo growing, Sangamo eventually purchased the entire plant."--Sangamon County Historical Society website (viewed 08/01/23).
