Fallingwater best exemplifies Wright’s philosophy of organic architecture: the harmonious union of art and nature. Owned and operated by the Western Pennsylvania Conservancy, Fallingwater opened to the public as a museum in 1964 and is designated as a National Historic Landmark and Commonwealth of Pennsylvania Treasure. Not only did Wright make his mark on the American landscape, but he also influenced those in his studio and more than 500 Taliesin apprentices. Wright’s work also was published and exhibited widely in the early part of the 20th century and went on to influence world architects, such as the major modernists of Europe. His impact also impressed upon the work of architects in Latin America, Australia, and Japan.
