References/Referenzen Paper Proposal Dr Amber Roberts, Andre Le Notre Fellow Ecole Nationale Supérieure de Paysage Towards a Modern Landscape: The Role of Referencing in Ian McHarg’s Early Research 2019 marks the fiftieth anniversary of landscape architect Ian McHarg’s seminal text ‘Design With Nature’. The book raised McHarg’s reputation to an international standing and widely disseminated the ecological approach that continues to be taught and practised by landscape architects across the globe. Prior to McHarg’s breakthrough method of landscape assessment and design less is known about how he developed his ideas and theories into cohesive approaches to landscape. In this paper I wish to discuss McHarg’s first major research project ‘Towards a Modern Landscape’ which immediately predated the publication of Design With Nature. The project spanned McHarg’s transition period between Scotland and America between 1955-1965 and was funded by the Rockefeller Institute. The project included the identification, filing and synthesis of articles based on the theme of Modernist Landscape Architecture from a wide range of books and articles published in international journals and in multiple languages. At the height of the project McHarg employed three full time research assistants to collate and classify the materials, resulting in a vast repository of information. The project was firstly propelled by McHarg’s frustration with the lack of information and dedicated reference sources on Modernist landscape architecture and secondly by his will to expand his repertoire and depth of understanding as a lecturer. I wish to present McHarg’s method of working in ‘Towards a Modern Landscape’ as a significant precursor to his later works. The referencing methodology McHarg developed for the project and the major role references continued to play in his subsequent work became fundamental to his processes of idea formation and development as an educator, author and practitioner. The project sheds light on a lesser known aspect of McHarg’s work through his early interest in Modernism yet also helps us begin to trace the origins of his later shift towards ecological concerns. The paper presents the findings of a post-doctoral research project on McHarg’s early works, the project was funded by The Paul Mellon Centre and archival research was undertaken at the Architectural Archives of the University of Pennsylvania in 2018/9.
