(1883–1969), German-American architect and educator, who founded the Bauhaus, a German art school that became a seminal force in architecture and applied art during the first half of the 20th century. His central thesis, which served as the school’s guiding principle, was that design (in any of its forms) should be functional, based on a wedding of art and engineering. This concept, which was expressed in his own buildings, had a profound influence on modern architecture.

Born in Berlin on May 18, 1883, Gropius studied architecture in Munich and Berlin-Carlottenburg. From 1907 to 1910 he worked in the offices of the German pioneering functional architect Peter Behrens in Berlin. In 1911 he joined the Deutscher Werkbund (German Work Union), formed to ally designers with machine production. Working with Adolph Meyer (1881–1929), Gropius designed the Fagus Works in Alfeld (1910–11) and the office building for the Werkbund exhibition in Cologne (1914), which made him known throughout Europe. After World War I he became the director of two Weimar art schools, which he reorganized in 1919 as the Staatliches Bauhaus (State Building School). At the Bauhaus he introduced a new approach to design education that emphasized the principle of uniting art and technology; students received a basic crafts training to gain an acquaintance with materials and processes. This method, which led to a heightened awareness of the realities of production, virtually revolutionized modern design. When the school was moved to Dessau in 1925, Gropius designed its buildings. They are marked by simplicity of shape, elimination of surface decoration, and the extensive use of glass.

Gropius resigned as director of the Bauhaus in 1928 to return to private practice. Opposed to the Nazi regime, he left Germany secretly in 1934, and after several years in England, he went to the U.S. to join the architecture faculty of Harvard University. As head of the department (1938–52), he introduced the Bauhaus concepts and helped to shape a generation of American architects. In 1946 he formed a group called the Architects Collaborative, which executed many important commissions, including the Harvard Graduate Center (1949), the U.S. Embassy in Athens (1960), and the University of Baghdad (1961). He designed the Pan Am Building (1963) in New York City in collaboration with the Italian-American architect Pietro Belluschi. Gropius died in Boston on July 5, 1969.
