John D. Rockefellerwas an American industrialist and philanthropist who founded the Standard Oil Company, which dominated the oil industry and was the first great U.S. business trust. He is the major historical figure behind the famed Rockefeller family and widely considered the richest American and biggest philanthropist in history.
Rockefeller was the eldest son and second of six children born to traveling physician and snake-oil salesman William (âBig Billâ) Avery Rockefeller and Eliza Davison Rockefeller. He moved with his family to Moravia, New York, and, in 1851, to Owego, in Tioga county, New York, where he attended Owego Academy. The family relocated to Strongsville, a town near Cleveland, Ohio, in 1853, and six years laterâafter attending and later dropping out of Clevelandâs Central High School, taking a single business class at Folsom Mercantile College, and working as a bookkeeperâRockefeller established his first enterprise, a commission business dealing in hay, grain, meats, and other goods.
Sensing the commercial potential of the expanding oil production in western Pennsylvania in the early 1860s, Rockefeller built his first oil refinery, near Cleveland, in 1863. Within two years it was the largest refinery in the area, and thereafter he devoted himself exclusively to the oil business.
In 1870 Rockefeller and a few associates, a group that included American financier Henry M. Flagler, incorporated the Standard Oil Company (Ohio). Because of Rockefellerâs emphasis on economical operations, Standard prospered and began to buy out its competitors until, by 1872, it controlled nearly all the refineries in Cleveland. That fact enabled the company to negotiate with railroads for favored rates on its shipments of oil. It acquired pipelines and terminal facilities, purchased competing refineries in other cities, and vigorously sought to expand its markets in the United States and abroad.
In 1881 Rockefeller and his associates placed the stock of Standard of Ohio and its affiliates in other states under the control of a board of nine trustees, with Rockefeller at the head. They thus established the first major U.S. âtrustâ and set a pattern of organization for other monopolies. By 1882 Standard Oil had a near monopoly on the oil business in the United States.

The aggressive competitive practices of Standard Oil, which many regarded as ruthless, and the growing public hostility toward monopolies, of which Standard was the best-known, caused some industrialized states to enact antimonopoly laws and led to the passage by the U.S. Congress of the Sherman Antitrust Act in 1890 (see also antitrust law). In 1892 the Ohio Supreme Court held that the Standard Oil Trust was a monopoly in violation of an Ohio law prohibiting monopolies. Rockefeller evaded the decision by dissolving the trust and transferring its properties to companies in other states, with interlocking directorates so that the same nine men controlled the operations of the affiliated companies.
In 1899 many of the companies that comprised the trust were brought back together in a holding company, Standard Oil Company (New Jersey), which existed until 1911, when the U.S. Supreme Court declared it in violation of the Sherman Antitrust Act and therefore illegal. Standard Oilâs questionable ethics were also taken to task by American journalist Ida Tarbell in her 19-part exposĂ© and commentary called The History of the Standard Oil Company, which was released in installments by McClureâs Magazine between 1902 and 1904.

A devout Baptist, Rockefeller turned his attention increasingly during the 1890s to charities and benevolence; after 1897 he devoted himself completely to philanthropy. He made possible the founding of the University of Chicago in 1892, and by the time of his deathâfrom a heart attack in 1937, shortly before his 98th birthdayâhe had given it some $35 million. In association with his son, John D. Rockefeller, Jr., he created major philanthropic institutions, including the Rockefeller Institute for Medical Research (renamed Rockefeller University) in New York City (1901), the General Education Board (1902), and the Rockefeller Foundation (1913). Rockefellerâs benefactions during his lifetime totaled more than $500 million.
Rockefellerâs life and work are discussed in Grant Segall, John D. Rockefeller: Anointed with Oil (2001); and Susan E. Hamen, John D. Rockefeller: Entrepreneur & Philanthropist (2011). Other treatments of Rockefellerâs life include Allan Nevins, Study in Power: John D. Rockefeller, Industrialist and Philanthropist , 2 vol. (1953); and David Freeman Hawke, John D.: the Founding Father of the Rockefellers (1980). A multifaceted view of Rockefeller is presented in Ron Chernow, Titan: The Life of John D. Rockefeller, Sr. (2013).
