Saxonia (Zeibig, Berger and Schumann)

In 1895 three of the mechanics, working in the factory of Arthur Burkhardt in Glashütte—Eduard Zeibig, Paul Eugen Straßberger and J. Schumann (who was a foreman in the factory), decided to leave and to found a new factory for calculating machines—Glashütter Rechenmaschinen-Fabrik Saxonia. In this factory was produced the successful calculating machine Saxonia. Later on in 1920 the factory Saxonia will merge with the factory of Burkhardt and the joined factory will continue his production up to 1929.

First models of the machine certainly are almost identical to the Burkhardt's Arithmometer, but later models had many improvements, such as a rotary setting lever by which a dust-tight encapsulation the mechanism was possible, moment cancellation mechanism, rolling box lid. There was even a model with a keyboard, instead of the traditional sliders of stepped-drum machines.
