Standard Oil Company was incorporated in Ohio in 1870, but the company’s origins date to 1863, when John D. Rockefeller joined Maurice B. Clark and Samuel Andrews in a Cleveland, Ohio, oil-refining business. Rockefeller bought out Clark in 1865, and Henry M. Flagler became a partner in the venture in 1867. The firm of Rockefeller, Andrews, and Flagler was operating the largest refineries in Cleveland when Standard Oil Company was incorporated.
