Architectural patronage was crucial for the thinking of Aby Warburg and his circle. In Hamburg the purpose-designed Kulturwissenschaftliche Bibliothek Warburg, completed in 1926, organized Warburg's remarkable library. From 1927 Warburg developed ideas about orientation in the radical transformation of a disused water tower into the Hamburg Planetarium. After the Warburg Institute transferred to London in 1933 this pattern of seminal architectural commissioning continued, including projects designed by the avant-garde practice Tecton during the 1930s, and culminating in the construction of the library's present home at Woburn Square, Bloomsbury in 1958. Warburg Models: Buildings as Bilderfahrzeuge follows this history, using archive photographs, architectural drawings and a series of architectural models to show how the Warburg scholars projected a connection between their own physical occupancy of architectural space and their shared ideas about intellectual order, cultural survival, and memory. MARI LENDING and TIM ANSTEY are both professors of architectural history at the Oslo School of Architecture and Design. Their continuing archive-based seminar on the relationship between the Warburg Institute and architecture has developed into an exhibition and a book, not least because of the skilled participation of their model-building students.
