After World War II, blood groups became a symbol of anti-racial science. This paper aims to shed new light on the post-WWII history of blood groups and race, illuminating the postcolonial revitalization of racial serology in South Korea. In the prewar period, Japanese serologists developed a serological anthropology of Koreans in tandem with Japanese colonialism. The pioneering Korean hematologist Yi Samyŏl (1926–2015), inspired by decolonization movements during the 1960s, excavated and appropriated colonial serological anthropology to prove Koreans as biologically independent from the Japanese. However, his racial serology of Koreans shared colonial racism with Japanese anthropology, despite his anti-colonial nationalism.

During the second quarter of the nineteenth century, an argument raged about the identity of a small freshwater fish: was the parr a distinct species, or merely the young of the salmon? This “Parr Controversy” concerned both fishermen and ichthyologists. A central protagonist in the controversy was a man of ambiguous social and scientific status: a gamekeeper from Scotland named John Shaw. This paper examines Shaw’s heterogeneous practices and the reception of his claims by naturalists as he struggled to find a footing on the “gradient of attributed competence” (Rudwick 1985). The case demonstrates the context-specific nature of expert-lay boundaries and identities and explores a range of material and linguistic resources available for negotiating them. Arguing for a view of Shaw’s trajectory as simultaneously one of being a “practical man” and of becoming a naturalist, the paper explores both the permeability of social hierarchies in knowledge production and their effective role in the regulation of competency.

Hans Egede (1686–1758), the famous missionary and natural historian in Greenland, was one of very few known Norwegian alchemists. This article seeks to place Egede’s alchemy in the context of the European alchemical tradition by identifying his sources in alchemical literature. Through an analysis of Egede’s account of an alchemical experiment performed by him in 1727, Ole Borch, Johann Joachim Becher, and Michael Sendivogius are identified as his main sources. Egede’s procedure and choice of materials are shown to be based on texts by these authors. The article argues that Egede’s alchemical interest was more pervasive than hitherto understood, through the demonstration of connections between his alchemical studies and his work as a natural historian. Further it is argued that Egede’s alchemy was not unique or anachronistic but exemplifies the continued belief in and practice of transmutational alchemy in Denmark-Norway in the early decades of the eighteenth century.

This article explores historical sociology as a complementary source of knowledge for scientific research, considering barriers and facilitators to this work through reflections on one project. This project began as a study of the emergence and reception of the infant disorganized attachment classification, introduced in the 1980s by Ainsworth’s student Mary Main, working with Judith Solomon. Elsewhere I have reported on the findings of collaborative work with attachment researchers, without giving full details of how this came about. Here, I will offer personal reflections arising from the process, and my work in what Hasok Chang has called history as “complementary science.”

The article retraces the shifting conceptualizations of psychological trauma in experimental psychopathological research in the middle decades of the twentieth century in the United States. Among researchers studying so-called experimental neuroses in animal laboratories, trauma was an often-invoked category used to denote the clash of conflicting forces believed to lead to neurotic suffering. Experimental psychologists, however, soon grew skeptical of the traumatogenic model and ultimately came to reject neurosis as a disease entity. Both theoretical differences and practical circumstances, such as the technical challenge of stabilizing neurotic symptoms in rats, led to this demise. Yet, despite their reservations, experimental psychologists continued to employ traumatic stimuli to produce psychopathological syndromes. In the 1960s, a new understanding of trauma evolved, which emphasized the loss of control experienced by traumatized animal subjects. These shifting ideas about trauma, I argue, reflect both varying experimental cultures, epistemic norms as well as changing societal concerns.

The tension between theoretical and practical knowledge was particularly problematic for trainee physicians. Unlike civic apprenticeships in surgery and pharmacy, in early modern England there was no standard procedure for obtaining education in the practical aspects of the physician’s role, a very uncertain process of certification, and little regulation to ensure a suitable reward for their educational investment. For all the emphasis on academic learning and international travel, the majority of provincial physicians returned to practice in their home area, because establishing a practice owed more to networks of kinship, patronage and credit than to formal qualifications. Only when (and where) practitioners had to rely solely on their professional qualification to establish their status as young practitioners that the community could trust would proposals to reform medical education, such as those put forward to address a crisis of medicine in Restoration London, which are examined here, be converted into national regulation of medical education in the early nineteenth century, although these proposals prefigured many informal developments in medical training in the eighteenth century.
