Answer:
Also, is this a question for school ? or just a question. I'd say Henry Ford. Why?
Explanation: He DID make automobiles, and that was really helpful, cause that.. like, really helped cities considering the size (Boston, New York, yeah.. it'd be painful just walking 3 miles for hours instead of driving for minutes) of the cities, walking would be tough. Like, you'd walk in slim and noodly, when you come at lookin' like Arnold. Anyway, back to the point. Henry Ford built a great industry inventing cars, and whatnot. This is why I think Henry Ford is the most helpful person during the industrial revolution.
