Adolf Hitler stole the idea for the iconic Volkswagen Beetle from a Jewish engineer and had him written out of history, a historian has sensationally claimed.  The Nazi leader has always been given credit for sketching out the early concept for the car in a meeting with car designer Ferdinand Porsche in 1935. His idea for the Volkswagen – or ‘people’s car’ – is seen by many as one of the only worthwhile achievements of the genocidal dictator.
