John D. Rockefeller, American businessman and philanthropist, founded the Standard Oil Company and Rockefeller University (born 1839)

John Davison Rockefeller Sr. was an American businessman 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 Southern United States.

Standard Oil Company was a corporate trust in the petroleum industry that existed from 1882 to 1911. The origins of the trust lay in the operations of the Standard Oil Company (Ohio), which had been founded in 1870 by John D. Rockefeller. The trust was born on January 2, 1882, when a group of 41 investors signed the Standard Oil Trust Agreement, which pooled their securities of 40 companies into a single holding agency managed by nine trustees. The original trust was valued at $70 million. On March 21, 1892, the Standard Oil Trust was dissolved and its holdings were reorganized into 20 independent companies that formed an unofficial union referred to as "Standard Oil Interests." In 1899, the Standard Oil Company acquired the shares of the other 19 companies and became the holding company for the trust.
