Ettore Bugatti, who had founded the car manufacturing company that bore his name, was a rather prickly gentleman.

Back in 1916 a Danish engineer and industrialist called Jørgen Skafte Rasmussen built a factory to make fittings for steam engines. The motorcar had only recently made an appearance and different methods of propulsion were being experimented with. Resmussen tried designing and building his own car, using a steam engine; in German a steam powered car is a 'Dampf-Kraft-Wagen', hence the name DKW. It didn't work.
