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 dedicated to 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 a definitive end to this prosperous factory. It should be noted that in the early years of production of these innovative machines a kind of patents were developed. Many of the calculators of the first years of the twentieth century were manufactured on the principle of the Odhner machine, and were built in all countries countless identical machines with different brands, among which stands out this example of the brand Brunsviga. Great machine to add to an important collection!
