Maurice B. Clark

Maurice B. Clark was a parter in a oil business with John D. Rockefeller in Cleveland. Later, toward the end of the Civil War (1865), the business that was started by Andrews, Clark and Rockefeller was terminated. Rockefeller bought Clarks share at auction for $72,500 and the company was left with just Rockefeller and Andrews. From then, in his building on Superior Street, John D. Rockefeller would gaze out at the barges of oil barrels passing by. Source: Titan: The Life of John D. Rockefeller, Sr., Ron Chernow, Random House, 1998.
