He was, for Joseph Pulitzer, "one of the most sinister figures that have ever flitted bat-like across the vision of the American people." According to the New York Times, "the work of reform is but half done... when people claiming to be respectable are not ashamed of being associated with a man such as he." He was Jay Gould, the individual who for a century has been singled out as the most despicable and unscrupulous of the Robber Barons. In this splendid biography, Maury Klein paints the most complete portrait of the notorious Gould that we have ever had. His Gould is a brilliant but ruthless businessman who merged dying railroads into expansive and profit-making lines, including the giant Union Pacific.
