Triumphator, together with Odhner and Brunsviga, was one of the three leading brands for pinwheel calculators. This machines work with a mechanism developed by W.T. Odhner in 1873, based in the Leibniz arithmometer. The company was founded in 1900 in Leipzig-Lindenau to produce vacuum tubes. In 1904 they hired a Brunsviga man, Otto Hokzapfel, and started producing the Triumphator calculators. During the first decades of the 20 the century they introduced and made machines with 10s-carry mechanism, in order to perform faster multiplication. This nice calculator bears the logo and model engraved in the metal case and painted white; we can see them to the left of the digit levers.
