THE ENVIRONMENT FORUM

Speaker: Sonja Dümpelmann, Ludwig-Maximilians-Universität (Munich)
Moderator: Joyce Chaplin, Harvard University

About the Event

Why do we plant and often protect trees in cities? Throughout history, humans have attributed healthy urban forests with a role in fostering a healthy citizenry. But how has this claim been substantiated, and why and how exactly did trees become integral to the Western idea of what constitutes a healthy city and planet? The presentation shows how trees were incidental and intentional vehicles for better understanding human-environment relationships. Knowledge about trees and their effects on human health and wellbeing was related to urbanization and by extension to colonial expansion and geopolitics. Regardless of the phenomenological, mythical, and therefore often hypothetical, and proto-scientific nature of much early tree knowledge, it had significant impact upon how early design professionals conceived of and shaped the built environment.

About the Speakers

Sonja Dümpelmann is a historian of landscapes and the built environment. She is professor and chair of Environmental Humanities at Ludwig-Maximilians-Universität in Munich. Her research and writing focus on nineteenth- and twentieth-century urban environments, especially in Europe and the United States. Of special importance to her work are the relationships between the inside and the outside, i.e. the relationships between architecture and landscape, center and periphery, theory and practice; those in power and those subjected to that power; intent and contingency; and the relationships between social and political processes and landscape transformation.

Dümpelmann is the author of Seeing Trees: A History of Street Trees in New York City and Berlin, Flights of Imagination: Aviation, Landscape, Design, and of a book on the Italian landscape architect Maria Teresa Parpagliolo Shephard (VDG Weimar, 2004). Her edited volumes include Landscapes for Sport: Histories of Physical Exercise and Health,  Airport Landscape: Urban Ecologies in the Aerial Age (together with Charles Waldheim), Women, Modernity, and Landscape Architecture (together with John Beardsley), A Cultural History of Gardens in the Age of EmpireGreening the City: Urban Landscapes in the Twentieth Century (together with Dorothee Brantz), and Pückler and America. Dümpelmann has guest-edited special journal issues and has published numerous book chapters, and articles in scholarly and professional journals, including Journal of Urban HistoryLandscape JournalLandscape ResearchPlanning PerspectivesStudies in the History of Gardens and Designed LandscapesStadtbauweltStadt und GrünDie GartenkunstJournal of Landscape Architecture, and Landscript.
