Karl Benz and the Single Cylinder Engine
Many men had tried to invent a horseless carriage. Karl Benz was only one of them. In 1885, he succeeded in building the first three-wheeled automobile. He didn t plan on starting his own automobile revolution. In fact, not many people bought his first car. But a century later the company he built is still in existence. And his contribution to self-powered vehicles has changed millions of lives.
