WESTCHESTER COUNTY, N.Y. -- David Rockefeller, a banker and philanthropist and the oldest living member of the Rockefeller family and the family patriarch since 2004, died Monday morning at the family estate in Pocantico Hills. He was 101.
The cause of death has not yet been released.
Rockefeller was the last son of world-renowned financier and philanthropist John D. Rockefeller, Jr. and grandson of John D. Rockefeller, Sr. the founder of Standard Oil.
Rockefeller served as chairman and chief executive of Chase Manhattan Bank
Rockefeller and his wife, Margaret "Peggy" McGrath, who died in 1996, had six children: David Rockefeller Jr., Abigail Aldrich "Abby" Rockefeller, Neva Rockefeller, Margaret Dulany "Peggy" Rockefeller, Eileen Rockefeller and Richard Gilder Rockefeller. Five of the children survive Rockefeller, except Richard Gilder Rockefeller, who was killed when his single-engine plane crashed near Westchester County Airport in White Plains in June 2014.
Westchester County Executive Rob Astorino lives in Mount Pleasant as did Rockefeller.
“I had the good fortune to know and work with David Rockefeller," Astorino said. "Despite his fame and wealth, he was down to earth in our dealings, which involved several projects while I was on the Mount Pleasant Town Board, such as the conversion of Stone Barns on the Rockefeller estate in Pocantico Hills into the world-famous restaurant that it is today.
"Among the many things he will be remembered for, he was a good neighbor and generous friend to Westchester County."
