Brunsviga Calculators - History The history of the Brunsviga calculators starts in 1892, when Grimme, Natalis & Co., a factory where sewing machines were manufactured, begins to produce them after the engineer Franz Trinsk bought the Odhner arithmometers patent. From 1892 to 1957 different models were produced. The most remarkable and popular ones were model B (1893-1927), model M (a smaller version of the latter), the Trinks Arithmotype (1910, first and only Odhner-type calculator which could print the outcomes) and the Trinks-Triplex (1911). The word Brunsviga is the Latin name of Braunchsweig, the city where the factory was located. During all its existence, the company made and sold nearly 500.000 units. In 1959 the factory was taken over by the Olympia Werke, a typewriting company. At the late 1960s production came to an end. The Trinks-Brunsviga calculators work with the pinwheel system developed by W.T. Odhner in the 1870s. It was inspired in turn by the arithmometer designed by Leibniz in the 16th century.
