ExxonMobil has its origins in Standard Oil, a company founded by what American philanthropist?
ExxonMobil has its roots in Standard Oil, a company founded in 1870 by John D. Rockefeller. One of the first multinational corporations, it found itself in breach of antitrust laws in 1911. The Supreme Court had the company split up, which ultimately made Rockefeller one of the richest men in the world, because he owned one quarter of all shares of the 34 newly created companies. The irony was further compounded when two of those companies, Standard Oil of New Jersey and Standard Oil of New York, were renamed "Exxon" and "Mobil" respectively, and re-merged 88 years after being broken up by the Supreme Court.
