Quote:David Rockefeller, the billionaire businessman and philanthropist who was the last in his generation of one of the country's most famously philanthropic families, died Monday. He was 101.

Rockefeller died in his sleep at his home in Pocantico Hills, New York, according to his spokesman, Fraser P. Seitel.

He was the grandson of Standard Oil co-founder John D. Rockefeller and the youngest of six children born to John D. Rockefeller, Jr.

With the passing of his sister and brothers, he became the guardian of his family's fortune and head of a sprawling network of family interests, both business and philanthropic, that ranged from environmental conservation to the arts.
