JAY GOULD (1836-1892). Gould, a railroad magnate, financier and a stock market manipulator, began his rise by controlling a small Vermont railroad in 1860. Over the next decade, he made a fortune by buying and selling railroads and manipulating their stock. His most famous railroad battle came in the late 1860s when, along with Jim Fisk and Daniel Drew, he struggled for control of the Erie Railroad against "Commodore" Vanderbilt. Gould went on to become "the most hated man in America" when his attempt to corner the gold market caused a panic termed "Black Friday" in September 1869. Turning towards Western railroads in the 1870s, he came to own or control numerous roads, including the Union Pacific and Kansas Pacific. It is estimated that he controlled about 10% of the American railroad track by 1880. He went on to gain control of the Western Union Telegraph Company and the New York elevated railroad before his premature death.
