John D. Rockefeller, world's richest man

It is the birthday of oil baron John D. Rockefeller (1839), who is widely considered the richest person in history. He built an empire that became Standard Oil Company, transforming into a fierce competitor who bought out his rivals or forced them out of business. Rockefeller so completely controlled every aspect of his industry that he spurred antitrust legislation that eventually broke up the oil and steel industries. A devout Northern Baptist, he never smoked or drank. He tithed generously to his church.  He considered his religion a major factor in his success. Rockefeller also set the standard for philanthropy, investing in educational institutions, public health initiatives, and overseas missions. His donations helped eradicate hookworm and yellow fever.
