Balance
notes: label: Description
content: Analytical balance with a “W. SPOERHASE SUCO. TO G. STAUDINGER & CO / GIESSEN / A.H. THOMAS. AGENT / PHILADA” inscription. Another inscription reads "D.R.G.M. No 58348." Carl Staudinger began making analytical balances and other precision instruments in Giessen in 1842. Wilhelm Spoerhase took charge of the firm in 1888. Arthur H. Thomas began bringing Staudinger/Spoerhase balances into the United States in 1899 and was soon supplying them to “practically every University, College and Technical School” in the country; some institutions had upwards of 75 of these instruments in actual use. The importation of these balances ceased with World War I.
