[00:00:00]Most people don't know this. John D.

[00:00:01]Rockefeller was the richest man who ever lived, and he gave almost all of it away. 1870, Cleveland, Ohio. A 31-year-old bookkeeper named Rockefeller founded Standard Oil. He wasn't lucky.

[00:00:12]He wasn't flashy. He was methodical. He bought refineries, then pipelines, then railroads. One by one, he controlled every step of getting oil from the ground to the customer. By 1880, Standard Oil controlled 90% of all oil refined in America. 90%. Competitors couldn't fight him, couldn't match his prices, couldn't survive. America had never seen anything like it. The government called it a monopoly. In 1911, the Supreme Court ordered Standard Oil broken into 34 separate companies, the largest corporate breakup in American history. Those 34 pieces became ExxonMobil, Chevron, BP America, Marathon Oil, companies worth trillions today. But here's what most people don't know. Rockefeller spent the last 40 years of his life giving his fortune away, universities, medical research, public health. He funded the research that eradicated hookworm in the American South. He built the University of Chicago from nothing. He gave away over $500 million.

[00:01:05]In today's money, over 10 billion. The most powerful businessman in American history spent half his life trying to give it all back. That's John D.
