Giedion is an architectural historian best known for his work, Space, Time and Architecture (1941) in which he applies an historical approach to contemporary architecture. In the book he notes that architecture, painting, art, and city planning were all part of a "true, if hidden unity, a secret synthesis in our present civilization." Giedion taught at the Massachusetts Institute of Technology and at Harvard. His last book was Architecture and the Phenomena of Transition (1969).
