Wright's design philosophy was heavily influenced by his association with Louis Sullivan, as well as the writings of the French architect Eugene-Emmanuel Viollet-le-Duc. These two originated the idea that architecture must be grounded in, and exemplary of, the highest and best aspects of the technology and culture out of which it arises.
Viollet-le-Duc came first; Sullivan further developed his ideas, originating the well-known formulation, "Form Follows Function". Without their fundamental guiding principles, Wright might have been a talented designer, but would not likely have reached the heights he did in his career. I describe the philosophical link shared by these three giants in the talk I gave recently at ATLOSCON, and which I will give again at the Chicago Objectivist Society's conference this coming Labor Day weekend.
As a celebration of his fabulous contribution to my very Top Value, I offer a few snaps of my visit to one of his greatest achievements, Fallingwater. The house was completed in the late 1930s, while Wright was in his late 60s. When most people would be at retirement age, Wright was in his prime.
