John Pierpont Morgan was an American financier and banker who dominated corporate finance on Wall Street throughout the Gilded Age. As the head of the banking firm that ultimately became known as J.P. Morgan and Co., he was the driving force behind the wave of industrial consolidation in the United States spanning the late 19th and early 20th centuries.
Over the course of his career on Wall Street, J.P. Morgan spearheaded the formation of several prominent multinational corporations including U.S. Steel, International Harvester and General Electric which subsequently fell under his supervision. He and his partners also held controlling interests in numerous other American businesses including Aetna, Western Union, Pullman Car Company and 21 railroads. Due to the extent of his dominance over U.S. finance, Morgan exercised enormous influence over the nation's policies and the market forces underlying its economy. During the Panic of 1907, he organized a coalition of financiers that saved the American monetary system from collapse.
As the Progressive Era's leading financier, J.P. Morgan's dedication to efficiency and modernization helped transform the shape of the American economy.
