Ludwig Mies van der Rohe
Ludwig Mies van der Rohe (1886-1969) was a German-born architect and furniture designer known for the design of skyscrapers in an unashamedly modernist, steel-and-glass style. He was director of the Bauhaus design school in Germany from 1930 until it was closed down by the Nazis in 1933, and emigrated to the United States in 1937. There he continued to practice (and subsequently received US citizenship), being perhaps best known for the Seagram Building in New York City.
