label: Description
content: Gustav David Sundstrand, the son of Swedish immigrants to the United States and a resident of Rockford, Illinois, applied for a patent for an adding machine in 1912, and was granted it in 1920 (U.S. Patent 1,329,028). He applied for a second patent in 1914, which was granted in 1916 (U.S. Patent 1,198,487). The Sundstrand originally was produced by the Rockford Milling Machine Company - by 1920 it was a product of Sundstrand Corporation, a closely related firm. Oscar Sundstrand, a brother of Gustav David, took over primary responsibility in improvements in the adding machine. During the 1920s, several business machine companies consolidated. The Elliott-Fisher Company acquired rights to the Sundstrand adding machine in 1926, and soon merged with the Underwood Typewriter Company. Hence the adding machine was renamed the Underwood Sundstrand.

content: This example is from considerably later in the history of the machine. The “8” in the model number indicates that the machine has a capacity of listing eight-digit totals, while the “P” signifies a portable electric machine with “Multiflex” control, allowing more rapid repeat addition and subtraction. According to the accession file, the donor acquired this machine secondhand in about 1953.
