This device is based on the original 1873 Odhner “pinwheel” design. Odhner was a Swedish immigrant who lived in Russia. The “Felix” name of this model refers to first head of the Soviet secret police Felix Dzerzhinsky, who started production of these devices in 1924 as a way employing young people during revolutionary times. Over the course of the 20th century, millions of Arithmometers were sold worldwide by several different manufacturers.
