The paper is based on a hitherto unexplored document (audiotape of an interview accompanied by a German transcript) from 1953, located in the Freud Papers at the Library of Congress. It contributes to a better understanding of the impact of Freud and of Psychoanalysis on personalities from the exact sciences, here represented by the noted applied mathematicians Richard von Mises and Hilda Geiringer from Vienna. The detailed discussion of the interview sheds some new light on the different roles of Kraus and Freud in the Vienna culture, on the Vienna Jugendkulturbewegung (youth culture movement) during WWI in which Geiringer was involved, on Freud’s and Siegfried Bernfeld’s standing around 1930 among German philosophers and psychologists, and on Wilhelm Fließ’ theory of periodicity, which von Mises—based on his attitude as an applied mathematician—defended against superficial accusations. Finally, new biographical material is provided for von Mises and the remotely related Freud family, and for Geiringer’s and von Mises’ early lives. The interview, which was taken during the Cold War, also allows conclusions as to how politics influenced the memories and views of the participants. Part of the aim of the paper is historical documentation of unknown material (letters by Karl Kraus and Wolfgang Köhler, one book review by Wilhelm Ostwald, a file on Richard Pfennig), including some correction of erroneous information in the literature.

In this paper, we wish to explore the role that textual representations play in the creation of new mathematical objects. We do so by analyzing texts by Joseph-Louis Lagrange (1736–1813) and Évariste Galois (1811–1832), which are seen as central to the historical development of the mathematical concept of groups. In our analysis, we consider how the material features of representations relate to the changes in conceptualization that we see in the texts.

Against this backdrop, we discuss the idea that new mathematical concepts, in general, are increasingly abstract in the sense of being detached from material configurations. Our analysis supports the opposite view. We suggest that changes in the material aspects of textual representations (i.e., the actual graphic inscriptions) play an active and crucial role in conceptual change.

We employ an analytical framework adapted from Bruno Latour’s 1999 account of intertwined material and representational practices in the empirical sciences. This approach facilitates a foregrounding of the interconnection between the conceptual development of mathematics, and the construction, (re-)configuration, and manipulation of the materiality of representations. Our analysis suggests that, in mathematical practice, distinctions between the material and structural features of representations are not permanent and absolute. This problematizes the appropriateness of the distinction between concrete inscriptions and abstract relations in understanding the development of mathematical concepts.

William Hunter's anatomical inquiry employed all of his senses, but how did his personal experiences with the cadaver become generalized scientific knowledge teachable to students and understandable by fellow practitioners? Moving beyond a historiographical focus on Hunter's images and extending Lorraine Daston's (2008) concept of an ‘ontology of scientific observation’ to include non-visual senses, I argue that Hunter's work aimed to create a stabilized object of the cadaver that he and his students could perceive in common. Crucial to this stabilization was the sense of touch and its interaction with other senses, creating intersensory knowledge of the cadaver. Through a close reading of his neglected posthumous publication An Anatomical Description of the Human Gravid Uterus (1794), I demonstrate that Hunter wrote extensively about touch and other sensory experiences, using comparative metaphors and other linguistic strategies to engender clear ideas of the cadaver in the mind of the reader. That these ideas could be consistent between practitioners was guaranteed by God, but required practitioners to appropriately reflect on their sensory experiences with cadavers. Hunter's experimental practice encompassed both simple and complex methods, all aimed at increasing the range of sensorial experiences he had with the gravid uterus. His preservations of these experiences in text, image and preparation could then be used to support further anatomical investigations.

This history of a statement attributed to the developmental biologist Lewis Wolpert exemplifies the making and uses of quotations in recent science. Wolpert's dictum, ‘It is not birth, marriage or death, but gastrulation which is truly the most important time in your life’, was produced in a series of international shifts of medium and scale. It originated in his vivid declaration in conversation with a non-specialist at a workshop dinner, gained its canonical form in a colleague's monograph, and was amplified as a quotation on a poster derived from an undergraduate project. Although it drew on Wolpert's authority and he accepted his authorship, it thus represents a collective sifting of earlier claims for the significance of prenatal existence through the values of 1980s developmental biology. Juxtaposing a technical term with major life events has let teachers engage students, and researchers entice journalists, while sharing an in-joke that came to mark community identity. Serious applications include arguing for an extension of the fourteen-day limit on human-embryo research. On this evidence, quotations have been kept busy addressing every audience of specialized knowledge.

In this article, I explore how the twin forces of imperial and entomological power allowed Britain to shape locust research and control across Africa, the Middle East and South Asia from the 1920s to the early 1950s. Imperial power came from the size of the formal and informal empire, and alliances with other colonial powers to tackle a common threat to agriculture and trade. Entomological authority came primarily from the work of Boris Uvarov and his small team of museum and fieldworkers based at the Imperial Bureau of Entomology (IBE), later the Imperial Institute of Entomology (IIE). I begin by discussing how Uvarov's phase theory of the origin of swarming changed the prospects for the control of locust plagues. The imperial gaze and networks of the IBE and IIE were suited to a problem that was transnational and transcontinental. In the 1930s, Britain was drawn into plans for international cooperation on locust organizations that met the needs of science, to give better sharing of knowledge, and the needs for science, to secure the resources for research and control. However, such organizations were only created during the Second World War, when new plagues threatened military operations, as I show in relation to the measures taken to control the red locust and desert locust. In the final section, I follow the fate of the wartime cooperation in initiatives to establish permanent control organizations. It is a story of the decline of British political power in locust affairs as the United Nations Food and Agriculture Organization and regional agencies took over. My account of British locust research and control reveals a neglected aspect of histories of entomology and imperial/colonial science, especially their international relations and the continuing importance of metropolitan research centres.

This paper examines two moments in the globalization of human genetics, focusing on the American University of Beirut as a site of interaction between American, European and Middle Eastern scientific actors and research subjects. In the interwar period, the establishment of clinical laboratories at AUB's medical school enabled the development of an informal large-scale programme to study human heredity through anthropometry and sero-anthropology. AUB's Middle Eastern students were trained in these techniques, and research results were disseminated locally in Arabic as well as in international scientific journals. In the post-war period, new technologies transformed human genetics into an internationally coordinated science with specialized laboratories. However, an attempt to establish such a lab at AUB during the 1960s ended in failure: the Anthropological Blood Grouping Laboratory functioned for only four years before closing. The American and British personalities who promoted the ABGL in Lebanon aimed to collect blood samples from across the region without committing to long-term relationships with local scientists and research subjects. As an ‘outpost’ for Western scientists, the ABGL embodied the neo-colonial structure of post-war human population genetics, both in its unfulfilled aspirations to serve metropolitan research agendas and in its marginalization of Middle Eastern scientists.

Fermentation is a cornerstone phenomenon in Cartesian physiology, accounting for processes such as digestion or blood formation. I argue that the previously unrecognized conceptual tension between the terms ‘fermentation’ and ‘concoction’ reflects Descartes's efforts towards a novel, more thoroughly mechanistic theory of physiology, set up against both Galenism and chymistry. Similarities with chymistry as regards fermentation turn out either epistemologically superficial, or based on shared earlier sources. Descartes tentatively employs ‘fermentation’ as a less teleological alternative to ‘concoction’, later renouncing the explicit use of the term, possibly to avoid chymical overtones. However, his continued use of analogies with fermentative processes in the natural world and in winemaking, coupled with a strong ontological commitment (the stance that the physiological processes are actual fermentations), leads to a reintroduction of natural teleology in his medical system, which I argue may be understood in an Aristotelian sense of ‘simple necessity’. The paper reveals a more nuanced account of Cartesian fermentative medicine, delineating some of its tensions with regard to chymistry as they play out in the dynamics of fermentation and concoction, and linking the analogies to fermentation processes to the difficulties in erasing teleology altogether.

This paper examines cave environments as unique spaces of knowledge production and shows how visualizations of natural cavities in maps came to be powerful tools in scientific reasoning. Faced with the challenge of limited vision, mapmakers combined empiricism and imagination in an experimental setting and developed specific translation strategies to deal with the uncertain origin of underground objects and the shifting boundaries between the known and the unknown. By deconstructing this type of cartographic representation, which has barely been studied, this paper furnishes surprising insights into the scholarly practices and tools used to deal with this considerable epistemic uncertainty and to signal credibility and trust to potential users. The array of maps used for this study includes both archival and published sources, depicting caves in Europe, America and Siberia.
