This first detailed study of Poelzig in English, with 350 illustrations, brings to light one of the most interesting architects working in Germany during a period when the course of architecture was profoundly changed. Written by a former student, it is an eloquent and personal memoir, a primary source and valuable first-hand account of a teacher and master builder who 'was an outsider even in his own time'. Posener follows Poelzig's career from his years in Breslau to Dresden and Berlin, discussing such works as the Festival Theater for Salzburg and the Capitol Cinema and concluding with his late designs. He provides a useful definition of the phases of Poelzig's work, including the moment at which it could be termed Expressionist. Pointing out that changes in German architecture between 1900 and 1935 were not as radical as they appeared, or wanted to appear, Posener draws attention to Poelzig's true strength - an idea of what architecture is that informs the whole of his work, despite the shifts in taste and technical progress that changed the formal language of buildings.
