The company was established first by August Horch and his first business partner Salli Herz on November 14, 1899 at Ehrenfeld, Cologne.[1] August Horch was a former production manager for Karl Benz. Three years later in 1902 he moved with his company to Reichenbach im Vogtland. On May, 10th, 1904 he founded the Horch & Cie. Motorwagenwerke AG, a joint-stock company in Zwickau (State of Saxony). The city of Zwickau was the capital of the South Western Saxon County and one of Saxony's industrial centres at the time. On July 16, 1909, August Horch, after troubles with Horch chief financial officer, founded his second company, the August Horch Automobilwerke GmbH in Zwickau. He had to rename his new company because Horch was already a registred brand and he did not hold the rights on it. On April 25, 1910 the brand Audi was entered in the company's register of Zwickau registration court. Audi is the Latin translation of horch, the imperative form of the German verb hören ("to hear"). The Audi name was proposed by a son of one of his business partners from Zwickau.[2] Both companies from Zwickau (Horch and Audi) were unified in 1932 with DKW and Wanderer to Saxony's Auto Union corporation. The Silver Arrow racing cars of the Auto Union racing team in Zwickau, developed by Ferdinand Porsche and Robert Eberan von Eberhorst, driven by Bernd Rosemeyer, Hans Stuck, Tazio Nuvolari, Ernst von Delius, were known the world over in the 1930s.
