They have their origin in the XVII century, when the first adding machines were built, characterized by using a gear-based operation, which arose to alleviate the work activity of those people engaged in accounting work. This type of machines were already much admired at the time, based on a system devised by Willigodt Odhner, the variant of the one developed by Leibniz in the 18th century. The German engineer Franz Trinks was the technical director of the Grimme, Natalis & Co factory in Brunswick (Germany). In 1892 he was granted a patent for the well-known Odhner machines to be marketed in Germany, Belgium and Switzerland under the brand name Brunsviga. In a short period of time, more than 500 machines were sold, mainly due to their reliability and low price. More than 500,000 machines were manufactured in various models. Without a doubt, the Brunsviga brand became the leader in the sale of calculating machines in Germany, without stopping production even during the two world wars. In the post-war period, industrial design was applied to these machines for the first time, developing technologically advanced models at high prices. In 1957 the Olympia factory of calculating machines bought 35% of the shares of the Brunsviga company, finally acquiring all of them in 1958. Machines of the Brunsviga brand were manufactured until 1964, when the entry into the market of electronic machines put an end to this prosperous factory.
