Automobile manufacturer. This man was first to use the assembly line to manufacture cars, rolling a car off the line every ten seconds. He was founder of the Ford Motor Company, and made his cars affordable for even the commonest family. He also created the 8-hour workday, and had his workers work five days a week, unlike most manufacturers at the time. He paid his workers $5.00 a day, so that eventually every other company had to raise their wages as well, hence increasing American living standards.
