This seminar explores architectural histories and theories related to human physiology from the late nineteenth century to the present. Our explorations extend from nineteenth-century theories of architecture style and human physiognomy to recent discussions of immunology and architecture. Concepts of human physiology inform a broad spectrum of architectural discourses: the design and management of buildings and urban spaces; theories of architectural form and environment; and, most provocatively, the writing of architecture history itself. Physiological concepts in architecture are far from neutral: They intersect with pseudo-scientific racial and eugenic theories, debates on gender and sexuality, and evolving concepts of physical capacity, impairment, and disability. Our goal is to understand how architects, historians, and theorists have shaped and responded to conceptions of human-ness, environment, health, and physical capacity within their practices. Participants in this seminar are expected to complete weekly readings, complete a few weekly assignments, lead or co-lead one discussion, and complete a final research project.
