When founded in 1967, the Master of Environmental Design (M.E.D.) Program offered a radically new way to understand and study the built environment in an architecture school setting by proposing a new object of study: an “environment” comprised of not only of masterpiece architecture, but of structures of all kinds, as well as infrastructure, technological systems, natural elements, symbolic systems, and the forces that shape this new totality. This symposium, convened by Eeva-Liisa Pelkonen and Jessica Varner, will include presentations from prior and current faculty and students of the M.E.D. Program and will celebrate the legacy of the program, which has enriched and complicated our understanding of our built and natural environment and helped launch careers in an equally wide range of fields: academia, journalism, curation, public policy, technology, real estate, and research.
