The First International Exhibition of Mathematical Devices is Held in Munich

The recently established Deutsche Mathematiker-Vereinigung held an exhibition in Munich of Mathematical and Mathematical-Physical Models, Apparatus, and Instruments in September 1893. This was the first international exhibition limited to mathematical devices, including calculating instruments; it reflected the huge growth in the field since the London exposition of 1876. The exhibition had been planned for the previous year but was canceled because of an outbreak of cholera in northern Germany.
