The Spanish influenza pandemic of 1918 caused well over fifty million deaths. The epicentre undoubtedly was China, where gene mixing of different virus strains occurred amongst aquatic, migrant birds. But where and when did the virus first infect (or spill over to) a human being? We take, as our starting point, a paper demonstrating that an infection causing the same symptoms as the influenza virus was widespread in New York during the winter of 1917-1918. The authors of that paper went on to suggest that the virus had probably reached North America from Europe, in the context of troop movement during World War I. Our own researches have focussed on this point. We show that outbreaks of serious respiratory disease, local in nature but causing unusual patterns of mortality, were indeed reported by scientists and doctors in army hospitals in England and in France, well before the first wave of the pandemic had arrived. We use the records of these hospitals, now held in the National Archives, to trace the progress of this disease amongst the individuals who fell ill. We examine contemporary reactions to this minor epidemic - an epidemic, we suggest, which acted as a herald wave of the pandemic yet to come. The latter part of our paper addresses the second question, as to how troop movement across the North Atlantic, once the United States had entered into war, may well have enabled the virus to spread from Europe to North America.

This special issue, which brings together six articles, seeks to explore the question of madness from non-European contexts (Latin America and Africa), taking part in the dynamic renewal of historiography on mental disorder and psychiatry in the 'Global South' over the past few years.1.

This article examines the historical transformation of childhood vaccination in the Netherlands between 1872 and 1959. It analyses how vaccination was reframed from an individual parental responsibility to a collective practice through the establishment of the 'Rijksvaccinatieprogramma' (National Immunisation Programme). I analyse this historical trajectory as a case of 'public health atomism', a strategy that achieves collective health by prioritizing individual health outcomes and local action. Rather than relying on top-down state mandates, the 'Rijksvaccinatieprogramma' was a consequence of co-operation between general practitioners, municipal health officials, civil society organisations, and volunteers. Drawing from published medical sources, parliamentary records, and material from local and national archives, this article provides a detailed historical account of how local governance and autonomy shaped vaccination practices, highlighting the role of the 'entgemeenschap' (vaccination community) as a key organisational model for situated collaboration. As such, it revisits childhood vaccination as an archetypical example of biopolitical state intervention, demonstrating how localised, flexible co-operation was instrumental in integrating vaccination into Dutch society.

The Pinel Sanatorium, the brainchild of Doctor Antonio Carlos Pacheco e Silva, a leading figure in Brazilian psychiatry, was inaugurated in 1929 in São Paulo as a private institution. It operated until 1944, during which time it recorded approximately 4,500 hospitalisations. In 30 psychiatric records, in addition to the usual clinical records, such as the Psychiatric Examination - in which the doctor records the elements he deems essential for identifying the mental illness from different sources of information, such as those provided by family members - attachments were found containing letters and short texts written by the inpatients. Addressed to different people, these letters, which were retained and evaluated by the doctors, played a central role in assessing the psychiatric conditions of the inmates. However, by being considered historical sources that reveal the 'point of view' of the mad, these documents are fundamental to the development of innovative approaches in the field of the history of madness and psychiatry. Based on the articulation between the context in which these records were produced, the social markers of difference that constitute the subjects, as well as the emotions expressed by the people who wrote them, the article sets out to answer two questions: (1) How the emotions expressed - both by the inmates and by their loved ones - were interpreted by psychiatrists and used to formulate diagnoses, and to define treatments and prognoses; (2) What meanings these emotions took on for the inmates themselves, in other words, how they put their experiences and subjectivities on display.

The U.S. National Library of Medicine holds two collections by Adolf Nichtenhauser (1903-53) that have become important sources for historians of medical and health films: an unpublished book-manuscript in which he surveys the history of medical and health films to around 1950, primarily in Europe and North America; and the valuable collection of documents he amassed partly during his research for this book-manuscript. Such is the richness of these collections that it is difficult to imagine a history of medical and health film that is not in some way indebted to Nichtenhauser. Indeed, his book-manuscript has become a standard citation in the historiography of medicine, health and film. Yet very little is known about Nichtenhauser himself, other than that he was a European immigrant to the United States who wrote this key history and died before its completion. This article seeks to do three things: to provide the first English-language biography of Nichtenhauser from his early life in Austria to his career in the United States; to use this biography to explain how he came to write this book-manuscript; and to explore the relationship between his historiography and efforts in the 1940s and 1950s to identify and solve problems with application of film to medicine and health.

Examining the systemic exploitation of mentally ill individuals, this study focuses on the practices of the British colonial administration in Kabba Province, Northern Nigeria (1900-1947). This research investigates how colonial authorities employed biopolitical strategies to categorise, control, and exploit this vulnerable population for labour, prioritising colonial economic and administrative interests. The study utilises a qualitative methodology, primarily analysing archival documents from the National Archives of Nigeria (NAK), Kaduna, and Arewa House Archives (AHA), to uncover the forced labour system's practices and rationalisations. Crucially, it incorporates oral sources from direct descendants of ethno-medical practitioners, former colonial staff, traditional chiefs, and learned community members. This oral history component provides vital intergenerational knowledge, contextualising archival findings and offering perspectives often absent from official records, ensuring a nuanced understanding of pre-colonial mental health practices and colonial-era lived experiences. Secondary literature on colonial biopower, mental health history, and regional history provides a comparative framework. Findings indicate the colonial administration systematically repurposed traditional care and established new mechanisms to identify, isolate, and compel mentally ill individuals into various forms of forced labour for infrastructure and economic extraction. In conclusion, this research significantly contributes to scholarship on vulnerable populations during colonialism, illuminating the intricate link between mental illness, labour, and power in colonial Nigeria, and informing contemporary debates on mental health, human rights, and historical justice.

This article examines the place of habit in the medical thought and practices of 18th-century Britain. Scholars, including Steven Shapin and Phil Withington, have shown that habit was important to the broadly humoral understandings of health, disease, and regimen that dominated in Europe for much of the early modern period. In this article, I offer the first sustained attempt to understand the role of habit in the medical thought of 18th-century Britain, focusing on the influential Scottish physician William Cullen. For the first time engaging with all of Cullen's work on habit, including his correspondence, pathological lectures, and clinical lectures, I show that medics of the 18th century developed a new understanding of habit, linked to changing ideas about the nervous system. Increasingly, they emphasised the role that habit could play in causing the periodical return of bodily functions, even when there appeared to be no plausible physical cause. In so doing, medics engaged with one of the key debates of the 18th century - the contested notion that human nature itself might be contingent on social and environmental conditions. For them, habit provided the means by which society could quite literally change the body. These ideas come through clearly in the striking suggestion - hitherto unnoticed - that menstruation was the product of habit, arising not from nature but from culture. Discussions of menstruation reveal the political stakes of habit, with links to highly contested debates about the role that bodies of different genders might play in society.

The article focuses on the export of cadaveric pituitary glands from communist Bulgaria in the 1980s, used for the production of human growth hormone. The case is explored in the broader context of practices and transnational networks for the supply of pituitaries. Special attention is paid to the changes resulting from the turn to the production of recombinant growth hormone in the mid-1980s, which put an end to the international 'market' of pituitary glands. In the last sections, different perspectives are explored to make sense of the case under scrutiny: those of bioethics and biolaw, on the one hand, and of bioeconomy in a globalising world, on the other.

This article explores the intersection of Cold War geopolitics, cultural psychiatry, and migration in Taiwan from the mid-1940s to the 1970s. Building on recent scholarship in cultural psychiatry and Cold War science, it examines how geopolitical tensions shaped psychiatric knowledge production in East Asia. Focusing on the psychological and social impact of the 1949 mass migration, when over a million Chinese immigrants arrived in Taiwan, alongside the clinical and academic work of Taiwanese psychiatrists, the study highlights how migration and societal upheaval became central research concerns. Operating under the authoritarian Kuomintang regime and within the constraints and opportunities of international politics, Taiwanese psychiatrists – most of whom were native-born with colonial backgrounds – drew on intellectual traditions from imperial Japan, fascist Germany, and the Cold War Western bloc. Navigating both global psychiatric discourses and local concerns, they positioned themselves as key contributors to the international development of psychiatric research. While their portrayals of Chinese character structure and family dynamics sometimes reflected essentialist views, their work also demonstrated a nuanced awareness of historical change and contemporary realities during a period of intense political repression and uncertainty. By analysing archival sources and medical texts, this article illuminates the complex interplay between geopolitics and psychiatric knowledge production in Cold War Taiwan.
