Deutz AG is a German internal combustion engine manufacturer, based in Porz, Cologne, Germany.

The company was founded by Nicolaus Otto, the inventor of the four-stroke internal combustion engine, and his partner Eugen Langen on 31 March 1864, as N. A. Otto & Cie, later renamed to Gasmotoren-Fabrik Deutz after moving operations in 1869 from Cologne to Deutz, located on the opposite side of the Rhine, also called “the wrong side” in Cologne (Germany).

During World War II, the company was ordered to produce artillery and operated under the name Klöckner Humboldt Deutz AG (KHD). In 1942, KHD was declared a war model company by the National Socialist German Workers’ Front for its “services to the defense economy”. In this context, the company relied heavily on the use of forced laborers.

In the 1942/1943 financial year, 2127 people, mainly from Western Europe, were forced to work at KHD. In some cases, up to 40 percent of the workers in the plants were forced laborers. The factory was almost destroyed by an air raid on the night of the 3rd and 4th of July 1943.

From 1892 to 1970, Deutz built locomotives in the power range from 4 HP to 2000 HP; until 1927, with gasoline engines, and from 1927, increasingly with diesel engine drive.

Commercial vehicles powered by Deutz engines were popular from 1960 to 1980.
