Explanation:
Henry Ford was a revolutionary because of his innovations in the automobile industry that led to more cars being produced at cheaper prices such that many more people could afford to own a car.
He did this first and foremost by introducing the Assembly line. He may not have come up with it but he made it famous. It worked by having workers remain stationary in a position while work came to them.
