Frank Lloyd Wright was an American architect who designed over 1,000 structures in different styles and types of buildings throughout his career from 1867 to 1959. Some of his most notable contributions included pioneering the "Prairie School" style of homes with low-pitched roofs, horizontal emphasis, and open floor plans that complemented the Midwestern landscape, as well as manipulating interior spaces and using new materials like stained glass. He was also a prolific writer and lecturer on architecture and left his mark on interior and fashion design.
