Geographer David Lowenthal is professor emeritus of the Department of Geography, University College London, and a renowned and prolific writer on nostalgia, heritage, and the spatial outcomes of concepts of the past and future. In several books on the politics of preservation, the meaning and value of landscape, society in the West Indies, and conceptions of nature, he has focused on the landscape and built environment as palimpsests of cultural attitudes to history. Lowenthal, who taught landscape history and studied urban environmental perception at Harvard GSD between 1966 and 1969, is a medalist of the Royal Geographical Society, Scottish Royal Geographical Society, and American Geographical Society; a fellow of the British Academy; and the recipient of many prestigious awards and prizes. A successor to The Past is a Foreign Country (1985), widely regarded as a classic, is due in print early next year (The Past is a Foreign Country—Revisited, Cambridge, 2015). Susan Nigra Snyder and George Thomas, lecturers in architecture, and Natalia Escobar, PhD student, will host the event on behalf of the GSD’s Critical Conservation program.
