Grimme, Natalis & Co, Braunschweig, Germany acquired 1892 the patents of the Odhner calculator and produced and marketed them under the name Brunsviga (latin for Braunschweig). The company was named Brunsviga Maschinenwerke AG in 1927 and was merged with the Olympia Werke AG, Wilhelmshaven in 1959. The name Brunsviga is strongly connected to Franz Trinks, who lead the development and innovations from the beginning up to 1926.
