@ Walter Gropius' career as an architect was interrupted by the first world war. But after leaving the army he focused his energies on the foundation of the Bauhaus design school. Its mission was to encompass the design of all functional objects # One of Gropius' prewar buildings was the Fagus factory (1911) near Hanover, the first in the world to feature curtain walls. He hung a glass facade on a skeletal frame, so that the windows 'turned the corners' without the need of brick columns # Gropius designed a new building for the Bauhaus in 1925. The school's philosophy was to combine art and design, and to reconcile craft tradition with the needs of industrial production. While director of the Bauhaus (1919- 29), Gropius employed such artists as Klee and Kandinsky to teach there # The so-called Existenzminimum housing complex was Gropius' most ambitious undertaking. Existenzminimum means 'bare necessities',and it reflected Gropius' concern to reduce architecture to its essentials, a desire also evident in his enthusiasm for the possib- ilities of prefab- ricated housing # Gropius left Germany in 1934 and lived in Britain before becoming a US citizen in 1944. While in Britain he designed a school in the village of Impington, near Cambridge. It was to have a great influence on postwar school design in Britain # In 1968 there was a major exhibition in London devoted to the Bauhaus. The aesthetic of the Bauhaus movement struck a particular chord in the design- conscious Sixties # Gropius said that "we have to destroy the separations between painting and sculpture and architecture and design - it is all one." Here, talking on BBC Radio, he gives an example of how art and architecture interact @ Gropius began his practical training in Peter Behrens' office, in 1907. Talking to Behrens "my own ideas began to crystallise as to what the essential nature of a building ought to be," Gropius said # Marcel Breuer went to the Bauhaus as a student in 1920. His bent tubular steel furniture (said to have been inspired by the handlebars of his bicycle) was to become a Bauhaus icon. Later, he rejoined Gropius in the USA # Philip Johnson was originally an architectural historian, and his writings did a great deal to establish the reputation of Gropius and other European modernists in the USA. Later, Johnson became an architect himself, studying under Gropius at Harvard # Like Gropius, Mies worked in Peter Behrens' office; he followed Gropius as director of the Bauhaus; and he, too, went into exile in the USA. But as an architect he was to prove more of a leader than Gropius @
