Winthrop Rockefeller was an American politician and philanthropist. Rockefeller was a son of American financer, John D. Rockefeller Jr. and Abby Aldrich Rockefeller. He is one of the grandchildren of Standard Oil co-founder John D. Rockefeller. As an entrepreneur in Arkansas, he financed many local projects, including a number of new medical clinics in poorer areas, before being elected state governor in 1966, as the first Republican governor of Arkansas since Reconstruction. Despite accusations of lacking insight into the concerns of low-income voters, Rockefeller was re-elected in 1968, and went on to complete the controversial integration of Arkansas schools.
