Carl Eugen Langen was a German entrepreneur, engineer and inventor, involved in the development of the petrol engine and the Wuppertal Suspension Railway. In 1857 he worked in his father's sugar factory, JJ Langen & Söhne, and after extensive technical training at the Polytechnic institute in Karlsruhe, patented a method for producing sugar cubes. In 1870 he co-founded Pfeifer & Langen, still in operation today. He sold this method in 1872 to Sir Henry Tate of England, founder of the Tate Gallery in London.
