Standard Oil Company, Inc., was an American oil production, transportation, refining, and marketing company that operated from 1870 to 1911. At its height, Standard Oil was the largest petroleum company in the world, and its success made its cofounder and chairman, John D. Rockefeller, among the wealthiest Americans of all time and among the richest people in modern history. Its history as one of the world's first and largest multinational corporations ended in 1911, when the U.S. Supreme Court ruled that it was an illegal monopoly.
