Ludwig Mies van der Rohe (1886 in Aachen – 17 August 1969 in Chicago) was a German architect.
Along with Walter Gropius and Le Corbusier, Ludwig Mies van der Rohe is widely regarded as one of the pioneers of modern architecture. Mies, like many of his post-World War I contemporaries, sought to establish a new architectural style that could represent modern times just as Classical and Gothic did for their own eras. He created an influential 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 highlight a strict yet elegant design. He developed the use of exposed steel structures and glass to define spaces, and he strove towards 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. He sought an objective approach that would guide the creative process of architectural design, and he is often associated with his quotation of the aphorisms, "Less is more" and "God is in the details".
