- Carl Staudinger of Giessen began making balances in 1842, showed his wares at international exhibitions, and was succeeded by Wilhelm Spoerhase in 1888. Arthur H. Thomas began bringing Staudinger/Spoerhase balances into the United States in 1899, and soon had supplied them to “practically every University, College and Technical School” in the country; in some institutions there were upwards of 75 instruments in actual use. The importation of these balances ceased with World War I.
