John Davison Rockefeller was the founder, in 1870, of the Standard Oil company. He was the son of William A. Rockefeller, Sr., and the brother of William A. Rockefeller, Jr., who had entered the oil refinery business in 1865, two years before John D. bought his first refinery. John's company absorbed William's refinery in 1867.
