John Davison Rockefeller III (March 21, 1906 – July 10, 1978) was a major philanthropist and third-generation member of the prominent Rockefeller family. He was the eldest son of John D. Rockefeller, Jr. andAbby Aldrich Rockefeller, and the grandson of John D. Rockefeller. His siblings were Abby, Nelson, Laurance,Winthrop, and David.
Rockefeller felt that he was predestined to manage the family endeavours as the eldest scion of his five-sibling generation – a view with which his brothers, particularly Nelson, took issue. His career before the 1960s was marred by bitter struggles with Nelson over control of Rockefeller Center and with his father over politics, particularly the anti-semitic and racist policies of the Williamsburg restoration.
Rockefeller eventually settled on philanthropy as his major interest (while Nelson and Winthrop devoted themselves to politics, Laurence to conservation and David to banking). He was a major force behind the establishment of the Council on Foundations, the Foundation Center, and Independent Sector. He took a leading role in organizing the Commission on Foundations and Private Philanthropy (better known as thePeterson Commission) and the Commission on Private Philanthropy and Public Needs (better known as the Filer Commission). He also made the initial donation to support Yale University's Program on Non-Profit Organizations, the first academic research center to focus on nonprofits.
In addition to his interest in philanthropy, Rockefeller made major commitments to supporting organizations related to East Asian affairs, including the Institute of Pacific Relations, the Asia Society, and the Japan Society. He was also a major supporter of the Population Council.

Early life
He received his preparatory education at the Browning School in New York City and the Loomis Institute, Windsor, Connecticut, in 1925. He went to Princeton University where he received high honors in economics and graduated in 1929 with the degree of Bachelor of Science, choosing industrial relations as the subject of his senior thesis. His interest in industrial relations stemmed from the family's role in the Ludlow Massacre, in which strikebreakers and security guards killed women and children of miners striking against the Rockefeller-controlled Colorado Fuel and Iron Company. Rockefeller's father worked to restore the family's public reputation by championing industrial relations and the work of William Lyon Mackenzie King, a pioneer in the field.
Commencing a lifelong commitment to international relations, he undertook a world tour after graduating from college, which concluded with assignments for the Institute of Pacific Relations conference in Japan.

Institutional positions/activities
John D. III would be the next Rockefeller manager for all family undertakings of social relevance. Since 1929, in total he sat on twenty boards of various institutions, most of which were family-related. The more notable of these were:

• Rockefeller University - then the Rockefeller Institute for Medical Research (Established by Senior);

• Colonial Williamsburg (Junior, Abby);

• Riverside Church (Junior);

• International House of New York (Junior);

• General Education Board - later the International Education Board (Senior);

• China Medical Board (Senior, Junior);

• Bureau of Social Hygiene (Junior);

• Industrial Relations Counselors (Junior).

In addition, he was at one time a member of the Council on Foreign Relations, the Foreign Policy Associationand the Institute of Pacific Relations, as well as being on the board of directors of Princeton University. In late 1950, he accompanied secretary of state John Foster Dulles on his trip to Japan to conclude a peace treaty, during which time he consulted with many Japanese leaders in practically every important sphere of that country's life.^[2]
He was a prominent third-generation family philanthropist in his own right and founder of the Asia Society, the major institution he established in 1956 to foster greater cooperation between Asia and the United States. He also founded the Population Council in 1952, and a reconstituted Japan Society. In addition, he set up the United Negro College Fund for the ongoing education of African Americans, carrying on the family tradition in this area with his grandfather's funding of the education of black women at Spelman College in Atlanta.
He was on his father's Advisory Committee in the family office, Room 5600. He was also president of the family's principal philanthropy run by family members, the Rockefeller Brothers Fund, from its inception in 1940 to 1956. In 1929, he joined the family's renowned Rockefeller Foundation; elected to the board in 1931 he subsequently became chairman of this major philanthropic organization for twenty years and was responsible for changing the focus of the institution.
The principal philanthropic institution he created was the JDR 3rd Fund in 1963, its major program being theAsian Cultural Program, created in 1967 to encourage East-West cultural exchange. The Fund was wound-up upon his death in 1979, but the Cultural Program continued as the Asian Cultural Council, which has provided grant assistance to more than 4,000 Asians and Americans in the area of the arts. Funding for its programs is derived from a combination of endowment income and contributions from individuals, foundations, and corporations in the United States and Asia.
In the mid 1950s, JDR III assumed the leadership of a committee of civic leaders who were working to createLincoln Center. He became the key figure in the fund-raising efforts and in forging a consensus among the civic leaders and others who were essential to its success. The Center itself was built over a period from 1959 to 1966. He was its first president, commencing in 1956, and he became its chairman in 1961. He served as chairman until 1970 when he was duly elected honorary chairman.^[3]
In the late 1960s, Rockefeller was responsible for the creation of the Commission on Foundations and Private Philanthropy (usually known as the Peterson Commission, headed by Peter G. Peterson) and the Commission on Private Philanthropy and Public Needs (usually known as the Filer Commission). He established theRockefeller Public Service Awards in 1958. In 1959, he received The Hundred Year Association of New York's Gold Medal Award "in recognition of outstanding contributions to the City of New York." In 1976, he received the S. Roger Horchow Award for Greatest Public Service by a Private Citizen, an award given out annually by Jefferson Awards.^[4] Rockefeller College at Princeton University was named in his honor in 1982.
John D. Rockefeller, III died in an automobile accident in Mount Pleasant, New York, near his home at theRockefeller family estate of "Pocantico", on July 10, 1978 at the age of 72. He was buried in Rockefeller Family Cemetery, Sleepy Hollow, New York.

On November 11, 1932 he married the socially connected Blanchette Ferry Hooker, who was to serve as chairman of the Asian Cultural Council from 1980 to 1990, and who established the Blanchette H. Rockefeller Fellowship Fund, in Japan. They had one son and three daughters:
