Frank Lloyd Wright, American architect, designed the Price Tower and Fallingwater (died 1959)

Frank Lloyd Wright Sr. was an American architect, designer, writer, and educator. He designed more than 1,000 structures over a creative period of 70 years. Wright played a key role in the architectural movements of the twentieth century, influencing architects worldwide through his works and mentoring hundreds of apprentices in his Taliesin Fellowship. Wright believed in designing in harmony with humanity and the environment, a philosophy he called organic architecture. This philosophy was exemplified in Fallingwater (1935), which has been called "the best all-time work of American architecture".

The Price Tower is a nineteen-story, 221-foot-high (67 m) skyscraper at 510 South Dewey Avenue in Bartlesville, Oklahoma, United States. One of the few high-rises designed by Frank Lloyd Wright, the Price Tower is derived from a 1929 proposal for apartment buildings in New York City. Harold C. Price Sr., the head of the pipeline-construction firm H. C. Price Company, commissioned the tower. The building was widely discussed when it was completed in 1956. It received the American Institute of Architects' Twenty-five Year Award in 1983 and has been designated a National Historic Landmark.

Fallingwater is a house museum in Stewart Township in the Laurel Highlands of southwestern Pennsylvania, United States. Designed by the architect Frank Lloyd Wright, it is built partly over a waterfall on the Bear Run stream. The three-story residence was developed as a weekend retreat for Liliane and Edgar J. Kaufmann Sr., the owner of Kaufmann's Department Store in Pittsburgh. The Western Pennsylvania Conservancy (WPC), which has operated Fallingwater as a tourist attraction since 1963, maintains 5,000 acres (2,000 ha) surrounding the house.
