Making Bill Gates look poor

American oil tycoon John D. Rockefeller (1839-1937) was rich. Really rich! By the time of his death his assets equaled 1.5% of the United States total economic output. In todays money, his net worth would be around $340 billion. This means he was roughly 4 times richer than Bill Gates ever was.

Some of the companies, which came out of this are still around and worth hundreds of billions. Ever heard of Exxon-Mobil, BP or Chevron?
