This course taught by Anooradha Iyer Siddiqi at Barnard College, Columbia University, out of the Barnard Archives and Special Collections and the Avery Drawings and Archives. The seminar follows the iterative pedagogical structure of an architectural studio, but emphasizes inquiry through open-ended project-based research, rather than making a design. Students pursue an independent research question, studying collections in New York or elsewhere, and learn several methods for gathering primary material. They collectively produce an annotated bibliography of secondary literature. Archivists and librarians assist them in studying the politics of archival collecting and accessioning, critical library database structuring, and public access. Primary and secondary research by students on a wide range of subjects is accessible through the Barnard Archives. The course redresses two perennial problems. The first is that the discipline of architectural history has neglected, and often rejected, the non-male or non-gender-conforming subject. The second is that it has overwhelmingly favored masculinist strategies for knowledge production. If these problems limit the critical capacity of architectural history and foreclose inclusive histories, they also hamper a student’s imagination of the past—and thus, the present and the future. Instead, an intersectional feminist approach to architectural research deploys the grounded historical study of places, institutions, and infrastructures to reflect on power.
