Henry Ford did not invent the car. Ford is considered to have made modern automobiles more accessible to a wider audience by speeding up the process of mass producing cars, and reducing the cost, beginning in 1914.
Karl Benz, a German man, is considered to have invented the car in 1886 with the production of his Benz Patent-Motorwagen. Before Benz, there were various attempts at steam-powered vehicles which had a similar form to the modern car. When Henry Ford started producing cars, he was building on ideas already developed by other people. Neither did he originate the process of using an assembly line to mass product cars, as this was already the method used by Ransom Olds to produce the Oldsmobile from 1902.
