单选题 Laurance Rockefeller, the middle brother of the five prominent and benevolent grandsons of John D. Rockefeller, who concentrated his own particular generosity on conservation, recreation, ecological concerns and medical research, particularly the treatment of cancer, died of pulmonary fibrosis at his home in Manhattan.
His career began on Wall Street almost 70 years ago, where he became a pioneer of modern venture capitalism, compounding his inherited wealth many times over. In the decades since he first took his seat on the New York Stock Exchange, he often used his native instinct for identifying the next big thing, not content simply to make more money but to make the money produce something of lasting value.
Less sociable than his older brother Nelson, who was a four-term governor of New York and the country's vice president under Gerald R. Ford, Laurance Spelman Rockefeller was also more reserved and private than his flamboyant younger brother Winthrop, who was governor of Arkansas. A philosophy major at Princeton he had long wrestled with the question of how he might most efficiently and satisfyingly use the great wealth into which he was born and which he later kept compounding as a successful pioneer of modern venture capitalism.
Using significant amounts of his money as well as his connections and prestige and negotiating skills he was instrumental in establishing and enlarging National Parks in Wyoming, California, the Virgin Islands, Vermont, Maine and Hawaii. As an active member of the Palisades Interstate Park Commission, he helped create a chain of parks that blocked the advance of sprawl, thus maintaining the majestic view that he first saw as a child looking out from Kykuit, the Rockefeller country home in Pocantico.
His commitment to wilderness, recreation and environmental conservation had many roots. Since childhood he liked to ride horses through unspoiled terrain. He was a passionate photographer who sought out new landscapes. Even before Laurance reached adulthood the Rockefellers had included parks among their many philanthropic projects.
Laurance was born on May 26, 1910. As Laurance matured he came to more closely resemble his grandfather than did any other family member, having the same pursed and seemingly serious expression that JohnD. Rockefeller often showed in photographs. According to family accounts, he was also the one who most closely revealed his grandfather's ability for profitable deals.
