This seminar will address the intertwined activities of the architectural office Lippsmeier + Partner (L+P) and its research arm, the Institut für Tropenbau [Institute for Building in the Tropics] (IFT). Based in the foothills of the Bavarian Alps, from the 1960s L+P and IFT practiced extensively in the “global South,” particularly in Tanzania. Focusing on “social infrastructure” projects in Dar es Salaam and Mwanza, the seminar will explore how L+P and IFT encountered and engaged with a decolonising society undergoing nation building processes. Drawing on archival research, fieldwork and interviews, it will investigate links to the German colonial past and the West German state as well as the agency of Tanzanian actors. The seminar will shed light on the entrepreneurial and simultaneously research-oriented functioning of this unique practice, entangled in the global developments of the post-WWII era.Rachel Lee is assistant professor at the chair of architectural and urban history at Delft University of Technology.
