Frank Lloyd Wright was an American architect born in 1867 who is known for designing over 400 structures. He helped pioneer the Prairie School style and is known for his organic architecture principles. Two of his most famous homes were Taliesin East in Wisconsin, built in 1911, and Taliesin West in Arizona, built starting in 1937. Both homes were designed based on Wright's principles of organic architecture and featured open floor plans, integration of interior and exterior spaces, and harmony with their natural surroundings.
