Brunsviga Calculating Machine
Brunsviga Calculating Machine

In 1878 Swedish engineer W. T. Odhner (1845-1905) invented and constructed a calculating machine of the "pin wheel and cam disk" type. Franz Trinks of the German firm Natalis & Co. realized the full potential of Odhner's idea and acquired the invention in 1892. Trinks manufactured this machine in an improved form and placed it on the market under the name Brunsviga. The Brunsviga machines were continually improved and soon became one of the most popular calculating machines in Europe.
