Iconic architect Frank Lloyd Wright was born on June 8, 1867 in Richland Center, Wisconsin. Wright has been called a genius, having designed buildings around the philosophy he called "organic architecture," which meant he designed structures that were harmonious with their natural surroundings. Perhaps the most famous example of this design philosophy is his 1935 work Fallingwater, which was voted "the best all-time work of American architecture" by members of the American Institute of Architects (AIA). Wright designed more than 1,000 structures during his lifetime, 532 of which were eventually built. In 1991, Wright was recognized as "the greatest American architect of all time."
