Sigfried Giedion was born in Prague to Swiss-Jewish parents. His father was 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 received his Ph.D. in 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 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 the 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==
