2. John D. Rockefeller
Rockefeller equals to such words as ‘success’ and ‘wealth’. John D. Rockefeller never finished high school, but it seemed the man knew how to manage his money and oil business better than any professor. The company named Standard Oil instantly became mega successful. It was broken up in order to avoid Rockefeller’s total monopoly of the oil industry. This famous business person and oil mogul could not boast impressive beginnings, however, he is currently considered to be one of the wealthiest men in world’s history.
