Grandson of oil magnate John D. Rockefeller, Nelson coveted the White House from childhood. "When you think of what I had," he once remarked, "what else was there to aspire to?" Before he was thirty he had helped his father develop Rockefeller Center and his mother establish the Museum of Modern Art. At thirty-two he was Franklin Roosevelt's wartime coordinator for Latin America. As New York's four-term governor he set national standards in education, the environment, and urban policy.
