August Horch (12 October 1868 – 3 February 1951) was a German engineer and automobile pioneer, the founder of the manufacturing giant which would eventually become Audi.
Horch was born in Winningen, Rhenish Prussia. His initial trade was as a blacksmith, and then was educated at Hochschule Mittweida (Mittweida Technical College). After receiving a degree in engineering, he worked in shipbuilding. Horch worked for Karl Benz from 1896, before founding A. Horch & Co. in November 1899, in Ehrenfeld, Cologne, Germany.
The first Horch automobile was built in 1901. The company moved to Reichenbach in 1902 and Zwickau in 1904. Horch left the company in 1909 after a dispute, and set up in competition in Zwickau. His new firm was initially called Horch Automobil-Werke GmbH, but following a legal dispute over the Horch name, he decided to make another automobile company. (The court decided that Horch was a registered trademark on behalf of August Horch's former partners and August Horch was not entitled to use it any more). Consequently, Horch named his new company Audi Automobilwerke GmbH in 1910, Audi being the Latinization of Horch.
