In the mid-1960s, there was widespread dissatisfaction in German architecture faculties: in the eyes of students and teaching assistants, the training of so-called artist-architects no longer seemed in keeping with the times. In protest, they independently organized their own interdisciplinary seminars and examinations. They committed themselves to the scientification of the architectural plan. During the period of student unrest, they debated the social uses of architecture and planning and tested participative models in practical contexts. Students printed flyers, campaigned in various political groups, and set up magazines. On the basis of interviews with contemporary observers of the scene, archival research, and contributions from authors, the book presents a detailed overview of these now almost “forgotten schools”. The editors were inspired not only by reviewing the historical events but also by the relevance they have for current debates on the professional profile of planners and architects and their sociopolitical responsibilities.
