How did Henry Ford change automobile manufacturing?

He came up with assembly line manufacturing where one person would do one thing and make a car on an assembly line, piece by piece. This allowed more autos to be made faster and cheaper, so the average person could afford them.

Before Henry Ford, a crafts person would make an automobile by hand, and it took longer, and was more expensive, and only the rich could afford them.

Mass production allowed the masses to own automobiles.
