Rockefeller, John Davison

Rockefeller, John Davison (b. Richford, N.Y., 8 July 1839; d. Ormond Beach, Fla., 23 May 1937) He matured in Cleveland, where he entered the oil refining business in 1862 and organized the Standard Oil Co. in 1867. He bought out or merged with competitors so rapidly that by 1879 he controlled 90 percent of US refining capacity, as well as a pipeline network and vast reserves of underground oil. In 1882 he consolidated his companies outside Ohio into the Standard Oil Trust. By 1892 Rockefeller was worth $800,000,000 and had become to reformers of the Progressive Era a symbol of monopoly power built upon cutthroat competition. Following the trust’s dissolution in 1911, Rockefeller retired and donated much of his billion-dollar fortune to philanthropy.
