Frank Lloyd Wright (1867-1959) is one of the most legendary figures in American architecture of the twentieth century. He was recognized in 1991 by the American Institute of Architects as “the greatest American architect of all the time.” He designed more than 1,000 structures in his 70-year career.

As his masterpieces, Fallingwater and Guggenheim Museum have been designated a UNESCO World Heritage Site. As he is known for coining the term “organic architecture”, he established his architectural style, believing that architecture should be at home in nature. He sets importance on the harmonious relationship between the occupant, structure, and landscape. Prairie houses in the early 20th century and the Usonian houses after the 1930s are remarkable examples of which are emphasized by horizontal lines.
