Some call it the end of an era of understated wealth. David Rockefeller, philanthropist, art collector and former CEO of Chase Manhattan bank–and the last surviving grandson of oil baron John D. Rockefeller–died in March at the age of 101. His properties have been up for sale since then, including his legendary art collection featuring works by Matisse, Cezanne, Gauguin, Seurat, and Picasso that headed for auction at Christie’s, his Upper East Side townhouse with an ask of $33 million and a retreat in Maine asking $19 million. The billionaire’s treasured Westchester estate, Hudson Pines, has just been listed at $22 million. Only 45 minutes from New York City, the property, which was home to the aforementioned art collection as well as the owner’s antique carriage collection and his collection of 250,000 beetle specimens–Rockefeller was an avid entomologist–seems a world away from the bustle of daily life.
