Ferdinand Porsche was an Austrian automotive engineer and honorary Doctor of Engineering. In 1906 he became Head of Development and Production at the Austrian Daimler-Moteren Gesellschaft. By 1922 he was Managing Director of his own company. In 1930, he resigned from Daimler-Benz AG and went on to open his own 'Design Office for Engines and Road Vehicles, Aircraft and Marine Vehicles'. He is best known for creating the first hybrid vehicle (gasoline-electric), the Volkswagen Beetle. Porsche received a contract from Hitler to build three prototypes from designs Porsche already had, such as the 1931 Type 12 car designed for Zündapp. The three cars were completed in the winter of 1936. However, the original car designs followed from the innovative ideas of Hans Ledwinka, which resulted in a lawsuit by Tatra against Porsche and his collaborators which was eventually settled by Volkswagen, but only several years after WWII. Daimler-Benz was contracted to build an additional 30 prototypes. A new city, "Stadt des KdF-Wagens", near Fallersleben, was founded for the factory.The city is named Wolfsburg today and is still the seat of Volkswagen.
