Jason Gould ( / ɡuːld /; May 27, 1836 – December 2, 1892) was an American railroad magnate and financial speculator who is generally identified as one of the robber barons of the Gilded Age. His sharp and often unscrupulous business practices made him one of the wealthiest men of the late nineteenth century.
