another architect idealist, but of a very different kind, was at work in america-- frank lloyd wright. wright's contributions to 20th-century architecture emerged well before world war i with his so-called prairie style, seen here in the robie house of 1908-1909, with its horizontal thrust, sheltering overhangs, terraces, and enclosed gardens. although always identified with a peculiarly american vernacular, wright's inspiration was eclectic, including viennese, japanese, and mayan sources. his work would be published in europe as early as 1910 and would have an influence internationally, including on the architects of the bauhaus. wright's concern for a marriage between architecture and landscape would lead to his 1936 house outside of pittsburgh-- falling water-- built on a natural rock over a small waterfall. but at the same time, in the difficult years of the 10s, he became more socially conscious, focusing on the needs of urban life. he remained nonetheless attached to nature, seen in the organic forms and use of natural light in such buildings as the johnson wax building of 1936
