The post-Civil War inventors generated ideas that transformed the economy, but they were not big businessmen. The evolution from technical innovation to massive industry took place at the hands of the entrepreneurs whose business gambles paid off, making them some of the richest Americans of their day. Steel magnate Andrew Carnegie, oil tycoon John D. Rockefeller, and business financier J. P. Morgan were all businessmen who grew their respective businesses to a scale and scope that were unprecedented. Their companies changed how Americans lived and worked, and they themselves greatly influenced the growth of the country.” Today, Jeff Bezos, Bill Gates, Mark Zuckerberg, and Elon Musk are some of the richest entrepreneurs in the world.
