Brunsviga

Brunsviga is the brand of mechanical calculators built by Grimme, Natalis & Co. of Braunschweig, Germany, and takes its name from the Latin form of the city.

They are pinwheel calculators: at the end of the nineteenth century the company licensed the design of Willgodt Theophil Odhner, and its engineer Franz Trinks improved it until it was fit for large-scale production.

In 1921 the company became a joint-stock company, and the Brunsviga name covers a family of models found in German and European offices for much of the twentieth century. Among them:

• the Brunsviga Trinks MR, the compact model from the years of the First World War;
• the Brunsviga 13, produced between the 1920s and the Second World War.

From 1922 to 1927 the neighbouring Rema Patent maker, also from Braunschweig, effectively merged into the firm, and some of its models were sold under the Brunsviga brand. It is one of the best-known European names among mechanical technologies of intelligence.
