Answer
Frank Lloyd Wright was influenced by Viollet-le-Duc, a French architect and theorist who emphasized the importance of structural honesty and the use of natural materials. Wright admired Viollet-le-Duc's belief in the organic nature of architecture and his rejection of historical styles. Wright's own work, such as the Robie House and Fallingwater, reflects Viollet-le-Duc's influence in its emphasis on natural materials, open floor plans, and integration with the surrounding landscape.
