Frank Lloyd Wright
Frank Lloyd Wright (1867 -- 1959) is possibly the most famous American architect and interior designer. His work includes original and innovative examples of many different building types, including offices, churches, schools, sky scrapers, hotels, and museums. Wright promoted organic architecture (exemplified by Fallingwater), was a leader of the Prairie School movement of architecture (exemplified by the Robie House and the Westcott House), and developed the concept of the Usonian home (exemplified by the Rosenbaum House). Wright authored 20 books and many articles, and was a popular lecturer in the United States and in Europe.
