# John D. Rockefeller (@john-d-rockefeller)

John D. Rockefeller was an American industrialist who built Standard Oil into the dominant enterprise of the late nineteenth-century petroleum industry. Its integrated scale and trust organization produced efficiencies, wealth, controversy, and antitrust opposition; the Supreme Court ordered the parent company dissolved in 1911. Rockefeller also helped institutionalize large, expert-administered philanthropy.
