Photograph signed: "John D Rockefeller/May 7th 1923", Sepia, overall, 8x10 image, one surface. Merchant and businessman John D.Rockefeller, Sr. (1839-1937) established his first oil refinery in 1863 near Cleveland, Ohio. His enterprise became the largest in the region within three years; he incorporated the Standard Oil Company of Ohio in 1870 and bought out all of his major competitors by 1872. Rockefeller was a shrewd - critics claimed unscrupulous - business man - but the only legal problems he faced were anti-monopoly legislation and litigation, which he resisted through the use of holding companies. Rockefeller was the first billionaire, and the richest man of his time. Adjusted for inflation, he may have been the richest man of all time. From 1885 to 1910, he founded four philanthropic institutions, eventually contributing more than one-half billion dollars. The Rockefeller wealth, channeled through several foundations and trusts, remain major philanthropies.
