TOUR DETAILS Our Penn Treaty Elm is a descendent of the original American elm under which William Penn, founder of the Commonwealth of Pennsylvania, signed a treaty of friendship with Lenape Chief Tamanend in 1682. General Paul Oliver, whose family owned the land where the historic tree stood, was instrumental in preserving its heritage. When the 600 year old tree was lost in a storm in 1810, Oliver was careful to propagate shoots of the tree on his property. He gifted one of these descendants as a sapling to the University of Pennsylvania on Arbor Day, 1896. During the planting ceremony on College Green, Chief of the U.S. Forestry Division B. E. Fernow announced that the American people had made two "great mistakes"- one in the mistreatment of the Native Americans, and the other in its degradation of American forests. "Penn, in whose memory we plant this tree today, made neither of these mistakes," he declared, and defined the Penn Treaty Elm's planting as a memorial to "moral rectitude and advanced national economic thought."
