By Erica Levi Zelinger A rchitecture, Frank Lloyd Wright believed, is life. It was that sentiment — the theory that organic buildings can be embedded in the natural world but still respect the environment in which they are married to — that allowed Wright to coin the term “organic architecture,” the spiritual union of form and function, the harmony of a building and its backdrop, and an understanding and appreciation for local topography. It was also this philosophy that made Wright such a visionary. To mark the 150th anniversary of the avant-garde architect’s birth and his more than 500 construction contributions to the design world, Pennsylvania’s trifecta of Frank Lloyd Wright homes celebrate the man the American Institute of Architects recognized as “the greatest American architect of all time.” Special events at Fallingwater in Mill Run, Kentuck Knob in Chalk Hill, and the Duncan House in Acme will commemorate the prolific architect and show visitors how a wooded wilderness, a rushing stream, and a nature reserve merge seamlessly with these Laurel Highlands homes to bring the outside in.
