The Kaufmann's entrusted Fallingwater to The Western Pennsylvania Conservancy in 1963 by Edgar Kaufmann, jr. who said, upon its dedication:

"As the waterfall of Bear Run needed the house to enter the realm of art, so the joint work of art, Fallingwater in its setting, needed the Western Pennsylvania Conservancy to enter a new life of public service…. I believe the Conservancy will give nature, the source, full due, and art, the human response to nature, full respect."
