 There were thousands of successful bankers and financiers; a central figure was J.P. Morgan, whose House of Morgan set up national financing programs for the steel, agricultural implements, shipping, and other industries.It also financed much of the British and French war efforts in World War I. John D. Rockefeller, of Standard Oil, expanded from a dominant position in oil to other industries as well as banking.Andrew Carnegie dominated steel until he sold out to Morgan in 1901.
