Editing Siegfried Marcus (section)

==Patents==
Marcus was the holder of 131 [[patent]]s in 16 countries. He never applied for a patent for the motorcar and, of course, he never held one. Nevertheless, he was the first to use petrol to propel a vehicle, a simple handcart, in 1870. It is uncertain whether the second Marcus car ran before 1890.<ref name=MBG />

In conjunction with Captain E von Wohlgemuth of the Imperial German Navy, Marcus invented an electrical ignition of ships cannons. The advantages of the system were that it allowed for the simultaneous firing of the cannons, or selection of a particular firing pattern, and the ability to fire them from the ship's bridge.<ref>{{cite journal |title=Electrical discharge of artillery on board men-of-war |journal=Telegraphic Journal and Electrical Review |volume=16 |date=16 May 1885 |pages=442–443}}</ref>
