Ludwig Mies van der Rohe was a German-American architect. He was commonly referred to as Mies, his surname. Along with Le Corbusier, Walter Gropius and Frank Lloyd Wright, he is regarded as one of the pioneers of modernist architecture.
Mies was a director of the Bauhaus, a seminal school in modern architecture. After Nazism's rise to power, and with its strong opposition to modernism, Mies fled to the United States. He accepted the position to head the architectural school at the Illinois Institute of Technology, in Chicago.
Mies sought to establish a new architectural style that could represent modern times just as Classical and Gothic did for their own eras. He created a new twentieth-century architectural style, stated with extreme clarity and simplicity. His mature buildings made use of modern materials such as industrial steel and plate glass to define interior spaces. He strove toward an architecture with a minimal framework of structural order balanced against the implied freedom of unobstructed free-flowing open space. He called his buildings "skin and bones" architecture.
