Widely thought to be the greatest American architect, Frank Lloyd Wright (1867-1959) was a true pioneer, both artistically and technically. At a time when reinforced concrete and steel were considered industrial building materials, Wright boldly made use of them to build private homes. His prairie house concept was the driving force behind some of his most famous houses and became a model for rural architecture across America. Wright's designs for office and public buildings were equally groundbreaking and unique. From Fallingwater to New York's Guggenheim Museum, his works are among the most famous in the history of architecture. This volume shows clearly that Wright saw man as the focal point for an architecture closely bound up with nature. This view of the world was a common factor throughout the rich diversity of his oeuvre.
