Captains of Industry (ep36) John Davison Rockefeller

John Davison Rockefeller Sr. (July 8, 1839 – May 23, 1937) was an American business magnate and philanthropist. He was one of the wealthiest Americans of all time and one of the richest people in modern history.

Rockefeller was born into a large family in Upstate New York who moved several times before eventually settling in Cleveland, Ohio. He became an assistant bookkeeper at age 16 and went into several business partnerships beginning at age 20, concentrating his business on oil refining. Rockefeller founded the Standard Oil Company in 1870.

He ran it until 1897 and remained its largest shareholder. In his retirement, he focused his energy and wealth on philanthropy, especially regarding education, medicine, higher education, and modernizing the American South.

Rockefeller's wealth soared as kerosene and gasoline grew in importance, and he became the richest person in the country, controlling 90% of all oil in the United States at his peak in 1900. Oil was used in lamps, and as a fuel for ships and automobiles.

Standard Oil was the greatest business trust in the United States. Through use of the company's monopoly power, Rockefeller revolutionized the petroleum industry and, through corporate and technological innovations, was instrumental in both widely disseminating and drastically reducing the production cost of oil.

Rockefeller's company and business practices came under criticism, particularly in the writings of author Ida Tarbell. The Supreme Court ruled in 1911 that Standard Oil must be dismantled for violation of federal antitrust laws. It was broken up into 34 separate entities, which included companies that became ExxonMobil, Chevron Corporation, and others—some of which remain among the largest companies by revenue worldwide.

Consequently, Rockefeller became the country's first billionaire, with a fortune worth nearly 2% of the national economy. His personal wealth was estimated in 1913 at $900 million, which was almost 3% of the US gross domestic product (GDP) of $39.1 billion that year.
