The Institute for Advanced Study's website offers a compelling account of Oswald Veblen's instrumental role, not only in convincing Flexner to locate the Institute in Princeton but also in acquiring land for the Institute campus. Veblen was a multi-faceted environmentalist, in that he designed the environment (old Fine Hall) in which the university's mathematics department (and for its first few years the Institute for Advanced Study) would prosper, and then helped to acquire the land for the Institute campus. Once he had convinced Flexner in 1934 of the value of locating the Institute on the edge of town, Veblen bargained with landowners over the next decade to help acquire 610 of the Institute's eventual 800 acres.
Most of those acres became preserved open space fifty years later. According to the NJtrails website, "A coalition of nonprofit organizations, with support from the New Jersey Department of Environmental Protection Green Acres program and Princeton Township, in 1997 preserved as open space a 589-acre property owned by the Institute for Advanced Study." About half of that acreage is woods, the rest of it farmland that continues to be farmed.
While he was seeking land for the Institute to acquire on the east side of Princeton, Veblen was also acquiring land of his own on the west side of town. Those 100 acres were later donated by Veblen and his wife to Mercer County as Herrontown Woods. Veblen's initiative and "ground-saving" work in the 1930s and 40s can be seen as laying the foundation for the remarkable efforts to preserve open space in Princeton a half century later.
It is worth noting that Veblen, over the course of his life in Princeton, was not only interested in open space where scholars and the public could walk, dream and reflect, but also the buildings within which scholarly work and nature study could be pursued. He took great interest in the design of the university's old Fine Hall and the Institute's Fuld Hall, and when he and his wife donated their house in Herrontown Woods to the county, they did so with the intent that it become a library and museum. He must have viewed the buildings, then, as an integral part of the beneficial and nurturing "environment" we inhabit.
It is up to us, even at this late date, to see this vision through, to view the Veblen House as a vital part of the Herrontown Woods nature preserve.
