He was the last of his generation in famous American family that thought their children wealth brings great responsibility. Even as children, he and his siblings had to set aside portions of their allowances for charitable giving.
That lesson lasted throughout his life; to mark his 100th birthday in 2015, Rockefeller gave 1,000 acres of land next to a national park to the state of Maine.
Rockefeller was the sixth child of John D. Rockefeller Jr. and the grandson of Standard Oil co-founder John D. Rockefeller.
He was the head of a sprawling network of family interests, both business and philanthropic, that range from environmental conservation to the arts and headed what is now JPMorgan Chase bank.
