The Rockefeller family

While the term "American dynasty" might technically be an oxymoron, it's hard not to notice the similarities between the Rockefeller family and noble lineages that have spanned the globe for centuries. Like royal families have done in other nations, the Rockefellers have had a profound and irrevocable impact on the United States—from the oil and banking industries to property development, to politics and philanthropy—which will continue to resound for generations to come. Beginning with John D. Rockefeller Sr., who founded the Standard Oil Company and became one of the world's richest men, the Rockefeller troupe also includes John D. Rockefeller III, Winthrop Rockefeller, Nelson Rockefeller, Laurance Rockefeller and David Rockefeller.
