Frank Lloyd Wright (1867–1959) was one of the most influential architects and designers of the 20th century, renowned for his philosophy of organic architecture, in which buildings, interiors, and furnishings are conceived as a unified whole. Rejecting historical imitation and industrial standardization, he developed a distinctive language of strong horizontal lines, open plans, and natural materials, most famously expressed in his Prairie houses and later works such as Fallingwater and the Guggenheim Museum. Beyond architecture, Wright designed furniture, lighting, and decorative elements as integral parts of his spaces, ensuring complete harmony between structure and detail. His work reshaped modern design by emphasizing the relationship between human life, form, and environment, leaving a lasting legacy that continues to influence architecture and interiors worldwide.
