A new architecture for America The scrutiny of the 20th century architectural design in America cannot commence without flashing back the critical work of Frank Lloyd, an American born architecture who lived between 1867 and 1959. Lloyd is one of the highly universally recognized and admired of all American known architects. His name is probably known in every part of the world, to laymen and even to architects and historians. However, unlike other influential architects whose reputations still lives because of the impact of their work in shaping the architecture of their time, Lloyd`s buildings and theories seem to have created only a small impact on the evolution of 20th-century architecture (Langmead 48-52). This paper seeks to understand the evolution of modern architecture and how buildings and early century architectural design were like before the American modern architecture come to exist. It will introduce in brief the engineer of American architecture Lloyd Wright. While the example of Lloyd`s buildings may have help nurtured the early development of known architects, the mature architectural work of these architects appear largely unaffected by Lloyd.
