Sigfried_Giedion

Sigfried Giedion (also spelled 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.
