Embodied ephemeralities: Methodologies and historiographies for investigating the display and spatialization of...

Exhibitions are embodied knowledge, and the processes of making exhibitions are also in themselves knowledge production practices. Science and technology exhibitions are therefore doubly of interest to historians of science: both as epistemic agents and as research methods. Yet both exhibitions and exhibition-making practices are ephemeral, as is the subsequent experience of the visitor. How can we research, interrogate, and understand both the productive creation of exhibitions and the phenomenologies and epistemologies of their reception and impact? "Exhibition histories" has become a significant field of late, most closely associated with research on art exhibitions but also extending to world and trade fairs, and now increasingly crossing over into histories of science and technology. It is not an easy task: the range of exhibition archive materials includes - but is not limited to - 35mm slides, architectural blueprints, models, drawings, briefs, memos, budgets, press films, reviews, and personal accounts. This primary material is distributed unevenly across public and organized repositories, closed commercial archives, the personal papers of designers, often embargoed national bureaus of information, and more. Further, the experience of visiting an exhibition leaves far fewer traces to follow, requiring the researcher to do different kinds of things with the same widely varied material. This paper proposes methodologies for historians of science and technology wishing to understand the spatialization of science in exhibition contexts, the impacts of science exhibitions, and the more elusive phenomenological aspects of the exhibition visitor experience. Historians of science must accurately historicize context while researching both along and against the grain of archival material left by the making of exhibitions, as well as understanding the embodied trajectories of visitors. The practice of making exhibitions can also offer the researcher critically valuable insights into what to look for - and what may be absent - in archival records.
