Frank Lloyd Wright
Frank Lloyd Wright (1887 - 1959) was an American architect. His career was varied, as he did not always please those who hired designers of buildings. While his early career was studded with commercial projects, he fell upon hard times and was reduced to designing houses for wealthy people in the greater Chicago area. In the third phase of his career, he was once again welcomed as the genius he was, and added greatly to the vocabulary of modern American architecture.
Wright, generally acknowledged as one of the greatest architects of the 20th cent., developed a highly original approach to residential design before World War I, which became known as the "Prairie Style." His early work, executed in and around Chicago, combined open planning principles with horizontal emphasis, asymmetrical facade elevations, and broad, sheltering roofs, as seen, for example, in his Robie House (1909). Wright, who stood apart from the European-derived modernist mainstream, continued to design buildings into his old age, producing some of his finest and most idiosyncratic works, such as the Guggenheim Museum. 
Wright's style involved several elements, not the least of which was his strong personality. He emphasized working with the land and the locality, preferring to use building materials which were locally available, and setting his projects "in to" their surroundings, rather than "against them". He was a perfectionist and a philosopher of sorts. He would not only design a "building", but also the furniture to be used in it, if it was a dwelling, or where the desks and filing cabinets would go - and how they were to be built - if it was commercial project.
One cannot help but be amazed at the subtle beauty of almost any building he designed, whether it was a corporate headquarters, or a house in Illinois. He would design every detail of a building, incorporating highly detailed Art Deco elements, for instance in windows and furniture.
Although his structures and ideas were a brilliant revolution, his work also had a tendency toward serious flaws - he is famously quoted as saying to a client who complained that the roof leaked over his desk, "move your desk".
The "Prairie House"
Wright espoused a philosophy of making buildings to fit their environment, and his greatest legacy in this area is the Prairie House. They were designed with overhanging eaves, to block the sun in summer, but to allow the winter sun in through the windows. They had broad horizontal lines, intended to make them blend in with the plains where they were located. While adapted to the American prairie (hence the name), the basic outline became what we know now as the "ranch house" - perhaps renamed to spare him the tragedy of being blamed for so many modern cookie-cutter developments.
For a time, Wright was devoted to designing dwellings for the prosperous. His houses are beautiful to look at, uncomfortable to live in, and almost immediately identifiable by his characteristic signature lines. They are typified by his Prairie and Usonian styles.
Mr. Wright built his own "dream house" in Wisconsin, called "Taliesin". Here he ran his operations, using many apprentices, perhaps unfairly - although one can say, that working unaccredited for a "master" is reward in itself. Tragedy befell him here, as the first building burned down.
At the headquarters for the Larkin Company Administration Building in Buffalo, New York, we see Wright at his prime, not only blueprinting the building, but also designing the workspaces. Another famous project was the S.C. Johnson headquarters.
- Frederick Robie House (1909) in Chicago, Illinois, a dramatic example of his late Prairie Style.
- Taliesin (1911 and 1925), at Spring Green, Wisconsin.
- Fallingwater (1934, 1938, 1948), a private home built over a waterfall near Mill Run, Pennsylvania. The house was originally built for the Kaufman family of Pittsburgh as their rural retreat. The house was designed to disrupt the natural setting as little as possible, and to create an outdoor atmosphere. The house is now a museum.
- Marin Civic Center (1957) in Marin County, California
- Price Tower (1952 to 1956), at Bartlesville, Oklahoma.
- The Guggenheim Museum (1956 to 1959) in upper Manhattan is one of his best-known "late career" accomplishments
Organic architecture seeks superior sense of use and a finer sense of comfort, expressed in organic simplicity.
God is the great mysterious motivator of what we call nature, and it has often been said by philosophers, that nature is the will of God. And I prefer to say that nature is the only body of God that we shall ever see.
I believe in God, only I spell it Nature.
Nature is my manifestation of God. I go to nature every day for inspiration in the day's work. I follow in building the principles which nature has used in its domain.
