The Marchant Calculating Machine Company of Oakland, Calif., was the oldest and one of the most influential American manufacturers of mechanical and electronic calculators. Established in 1911, the firm quickly built up a national sales network. Recognizing that the term "calculating machine" had fallen from use, the firm formally changed its name in 1952 to Marchant Calculators, Inc. In 1958 the company merged with Smith-Corona, Inc., a manufacturer of typewriters, adding machines, and cash registers. A slow decline followed for the combined firm, as electronic computers began performing the tasks of Smith-Corona Marchant's machines. SCM stopped selling calculators in 1973. Over 150 of Marchant's products and related documentation are in the Smithsonian collections.
Norman G. Hough, Sr., presumably distributed Marchant cacluating machines in Washington, D.C. It is not known whether he was the same Norman G. Hough who directed a trade organization for lime and concrete from the 1910s to the 1930s.
