Sigfried Giedion (sometimes misspelled Siegfried Giedion; 14 April 1888, Prague – 10 April 1968, Zürich) was a Bohemian-born Swiss historian and critic of architecture. His ideas and books, Space, Time and Architecture, and Mechanization Takes Command, had an important conceptual influence on the members of the Independent Group at the Institute of Contemporary Arts in the 1950s. Giedion was a pupil of Heinrich Wölfflin. He was the first secretary-general of the Congrès International d'Architecture Moderne, and taught at the Massachusetts Institute of Technology, Harvard University, and the ETH-Zurich.
In Space, Time & Architecture (1941), Giedion wrote an influential standard history of modern architecture, while Mechanization Takes Command established a new kind of historiography.
Sigfried Giedion was the son of a textile manufacturer from Zugersee. He graduated from the University of Vienna in 1913 with a degree in engineering. Not wanting to enter the family business, he wrote poems and plays, one of which was staged by Max Reinhardt. He then studied art history in Munich with Heinrich Wölfflin , graduating in 1922 with a thesis on Romanesque and late Baroque Classicism. This work aroused the interest of A.E. Brinckmann, a well-known art historian, who invited him to Cologne, an offer that Giedion refused because he was not interested in an academic career. Instead, in 1923 he attended the Bauhaus, where he met Walter Gropius. From that meeting he got closer and closer to the Bauhaus and its protagonists, becoming himself a precursor of the modern movement.
In 1928 he founded, together with Le Corbusier and Helène de Mandrot, the CIAM, of which he was also general secretary. In the same year he took part in the collective initiative Werkbundsiedlung Neubühl, one of the first residential centers in the style of the modern movement, remaining on the steering committee until 1939. He was also the builder of the Doldertalhäuser in Switzerland , which he saw as a manifesto of the new architectural movement, as well as founder of Wohnbedarf AG, a construction company close to the modern movement . Through countless interventions in international trade journals, he expressed his support for Le Corbusier's League of Nations project in Geneva, won in 1927 but disqualified because the submission was in the wrong medium.
In 1938/39 he taught at Harvard University at the instigation of Gropius, where he gave the Charles Eliot Norton Memorial Lectures. These helped form the basis for his work, Space, Time and Architecture, the history of the modern movement published in 1941. In 1946 he became a professor at the ETH-Zürich (Federal Polytechnic School), a post he held until the 1960s, and which he alternated with another at MIT in the United States of America. During this time he wrote busily, both as a CIAM editor and as an independent author, about his research on modernity, most notably Mechanization Takes Command, a critical history of mechanization seen in its historical and sociological aspects.
Personal life and family
In 1919 Giedion married Carola Giedion-Welcker, whom he met while they were both students of Wölfflin in Munich. She created a circle of avante-garde artists in Switzerland, which included Hans Arp and Aldo van Eyck. Their daughter Verena married the architect Paffard Keatinge-Clay.
