Short-beam balance in a wooden frame with glass sides, probably made by C. Staudinger, a balance maker who began in business in Giessen in 1842, or by his successor, Wilhelm Spoerhase. An Arthur H. Thomas advertisement in Chemical Abstracts (1910) stated that Staudinger balances were “in use in nearly 300 Universities, Colleges, and Technical Schools in the United States and Canada,” and in some of these institutions there were “upwards of 50 instruments in actual use.”
