Widely thought to be the greatest American architect Frank Lloyd Wright (1867-1959) was a true pioneer both artistically & technically. At a time when reinforced concrete & steel were considered industrial building materials Wright boldly made use of them to build private homes. His prairie house concept--that of a low sprawling home based upon a simple L or T figure--was the driving force behind some of his most famous houses & became a model for rural architecture across America. Wrights designs for office & public buildings were equally groundbreaking & unique. From Fallingwater to New Yorks Guggenheim Museum his works are among the most famous in the history of architecture.
