 The dominant force in the oil industry was Standard Oil, controlled by John D. Rockefeller.Modern-day ExxonMobil, Atlantic Richfield, Chevron, Sohio, Amoco and Continental Oil all trace their ancestry to various parts of Standard Oil.In March 1906, Commissioner of Corporations James Rudolph Garfield submitted a report to President Roosevelt, alleging large-scale rebating in Standard Oil shipments.
