ROCKEFELLER, JOHN DAVISON, JR. ) , American capitalist, born in Cleveland, Ohio, Jan. 29, 1874, and educated at Brown university (A.B., 1897). After a few years of business experience in his father's offices he became his father's assistant in the management of the enterprises, espe cially those of a philanthropic nature, which the latter had devel oped. Upon the elder Rockefeller's retirement in 1911, John D. Rockefeller, Jr., succeeded to many of the directorates, and became ultimately the elder's plenary representative in the admin istration of the Rockefeller interests. A number of the business directorates were subsequently relinquished, and a larger propor tion of the son's time was given to philanthropic and civic under takings. He became associated with his father before the first benevolent corporation was chartered and participated in the development of all of them. He became chairman of the board of the Rockefeller Foundation, a trustee of the Rockefeller Institute, and a director of the General Education Board. The serious
strike in the Colorado Fuel and Iron Company in 1912-13 drew his attention to industrial relations and he became much interested in industrial representation. He has interested himself in better housing conditions in New York city, and especially in the build ing of model apartments, both for white people and for the negro population. He has also financed the work of many separate scientific undertakings, notably the Byrd flight to the North Pole in 1926. In 1928 he offered $10,000,000 to Egypt to help establish a museum for her antiquities, which was declined.
For his other philanthropies see ROCKEFELLER BENEFACTIONS. Be sides numerous articles, he published The Colorado Industrial Plan (1916) and The Personal Relation in Industry (1924).
