I saw a big wall with a man, who had something like a bicycle at his side. It is of Carl Benz. It seems, that they aren't sure how to write it correctly, because I found Carl on that wall, but Karl on wikipedia. I saw that he was born in Karlsruhe, which is only about 20 km from Bruchsal.
Karl Friedrich Benz (December 6, 1844 – April 4, 1929) was a German engine designer and automobile engineer, generally regarded as the inventor of the gasoline-powered automobile. Other German contemporaries, Gottlieb Daimler and Wilhelm Maybach, also worked independently on the same type of invention, but Benz patented his work first and, after that, patented all of the processes that made the internal combustion engine feasible for use in automobiles. In 1886 Karl Benz was granted a patent for his first engine, which he designed in 1878.
Karl Benz (Related to the Benz family today) was born Karl Friedrich Michael Vaillant, in Karlsruhe, Baden (now part of Germany), to locomotive driver Johann George Benz and Josephine Vaillant. When Karl was two years old, his father was killed in a railway accident, and his name was changed to Karl Friedrich Benz in remembrance of his father.
