Burroughs bookkeeping machines developed from a combined calculating machine and typewriter developed by William Hopkins of St. Louis and sold by the Moon-Hopkins Billing Machine Company from about 1906. In 1921 Burroughs purchased patent rights to the machine and soon moved production to Detroit. Burroughs would sell accounting into the 1960s. Many examples of these machines in the Smithsonian collections come from that company’s Patent Department.
