This article argues that Walter B. Cannon's changing model of the body tracked the transformation of twentieth-century American liberalism from laissez-faire autonomy to managed adaptation. At stake throughout was the problem of reconciling the autonomy of parts with the integrity of the whole. His early studies of digestion-an invisible hand within-aligned with faith in spontaneous self-regulation. Progressive-era work on fear and rage reframed disruption as purposeful mobilization, while World War I exposed its limits in shock and collapse. In response, Cannon articulated homeostasis as a grammar of resilience-feedback, buffers, and margins of safety-that recast purpose as regulation rather than destiny. Read together, these shifts show science and politics moving in tandem: autonomy preserved through rule-bound coordination in complex systems. This article thus revises the two-track portrait of Cannon (scientist here, citizen there) and situates his "social homeostasis" within interwar democratic reform and New Deal liberalism, where institutional redundancy and welfare safeguards stabilized freedom under strain. Recovering this liberal physiology clarifies how Cannon offered a democratic counterpoint to authoritarian decisionism and neoliberal discipline, and why his idiom of care, redundancy, and repair remains salient for crises of the twenty-first century.
The introduction of water gas for house lighting in the United States posed a significant risk to public health in the years between 1875 and World War II. Water gas was superior to the older coal gas used as an illuminant but a far more lethal source of asphyxiation. Its introduction generated a battle between gas companies and public health experts who wished to prohibit use of the new gas. The companies prevailed; Massachusetts and later national data reveal that the victory of water gas led to death rates from asphyxiation that exceeded those from communicable diseases such as measles and scarlet fever. Yet by the 1920s economics incentives were reducing the role of water gas. and, as gas use evolved from illumination to heating and cooking, the market focused gas companies on the danger that asphyxiations from faulty appliances might frighten away new businesses, a concern that was reinforced by public health experts and state and local regulation. In response, the American Gas Association developed appliance safety standards and a standard gas code that is the basis for all modern gas regulations.
Decades before medical definitions of developmental normalcy revolved around statistical averages, nineteenth-century medical scientists identified a non-statistical "normal" that cohered within racial groups but was not generalizable across them. Using early child medicine treatises and anatomical, physiological, and ethnological texts, this article argues that nineteenth-century child development science was a race-making enterprise. The first sections analyze texts on child development and disease, identifying the racial parameters of developmental norms and the developmental events most frequently associated with racial differentiation: cranial suture closure and puberty. The following sections argue that variable rates of development and the degree of synchronicity between mental and physical development produced racial hierarchies and threatened racial degeneration. By examining "ethnic" classifications of idiocy, in which developmental timing considered typical for Black children was pathologized in White children, this article argues that developmental disorder posed a threat to racial order. As Darwinian evolutionism introduced scientific and social concerns about the historical contingency of racial progress, the clinical management of child development acquired newfound importance as a safeguard for White racial purity. Joining histories of nineteenth-century child development science and antebellum medical cultures with disability history, this article offers a pre-history of "developmental disability" as a racial category.
The belief in the power of the imagination of parents, and especially of the mother, to influence the features of the foetus has been widespread since ancient times. The first reference is in Genesis 30:25-43. It tells the story of how Jacob showed his father-in-law's ewes and goats coloured branches (stripped branches) during the mating season in order to produce spotted offspring. The theory refers not only to animals, but also to human beings, as various sources testify. The power of female imagination could extend from the moment of coitus through to the entire pregnancy, giving rise to congenital features in the foetus. Starting from the widespread idea of the female imagination as a disruptive factor in the entire process of the formation of the future individual, the aim of this article is to focus on one specific aspect of the question: namely, the origin and development of the belief that 'bastard' children resemble their putative fathers rather than their real fathers. To this end, the most significant medical and philosophical sources will be considered, from the origin of this belief, in the late Middle Ages through to the early modern period.
The colonial project was both parasitic and extractive. Its resource extraction imperative depended on maintaining a reservoir of cheap labour, whose supply required that they encourage and sustain high birth rates in the colonies. Maternal healthcare was therefore key to this project. The period 1930 to 1960, which we examine, was also characterized by increased African political agitation and internationally, by deepening global liberalism. Advocates of the latter called for colonial reforms, including some political participation of the growing African middle class. This, plus political changes in Britain at the time, put British colonial officials in Africa under pressure to bring about some reforms, including healthcare services. In Nigeria's Ibadan, the colonial regime initiated a training scheme for Africans to become midwives. They also recognized and mainstreamed in their medical service the institution of traditional birth attendants (known locally as Iya Abiye). We view this effort as a convenient response of the colonial officials to the shortage of medical personnel in Nigerian rural areas. These changes also reveal the rudimentary nature of health service delivery further away from urban areas. The introduction of Iya Abiye signals a shift in colonial health policy to an accommodative one due to the continued popularity of Iya Abiye in Yorubaland. By co-opting Iya Abiye into the mainstream maternal health system, colonial Nigeria officially became a medical pluralist society characterised by implementation challenges amidst some successes.
This article tracks the emergence of specific social work policies and practices designed to meet the needs of HIV-affected families with children. The article outlines the tense atmosphere into which HIV-related family social work emerged. It then describes how HIV-affected children and their families were first recognized as a specific client group with a unique constellation of needs, outlining the scramble to assess the statutory services' obligation to this emerging group, and the work to create new information, policies, and texts to meet these responsibilities. These texts envisioned the social workers' roles as that of carer, mediator, collaborator, information provider, and advocate, offering guidance on the medical and social dimensions of HIV and AIDS, alongside warnings about the emotional toll this work took on workers and the pitfalls of prejudice. The final section of the article examines how social workers met the needs of HIV-affected families with children on the ground, looking at how the needs of parents and children in Edinburgh were met through collaborative work between statutory and voluntary workers, alongside those living with HIV.
In 1964 Bombay surgeon P.K. Sen proposed a new operation for coronary artery disease. His "snake heart" procedure (or "transmyocardial acupuncture") sought to restore a reptilian form of circulation to the human heart. Despite its peculiar therapeutic rationale and limited evidence of its efficacy, the operation was taken up by surgeons around the world. By 1970, however, it had been set aside, done in by critique and a new competitor. Sen's therapeutic concept was surprisingly revived a decade later, not because of a better rationale or convincing evidence of efficacy, but because of the advent of surgical lasers. This case study highlights important features of late-twentieth-century surgery. First, what are the sources of surgical innovation and inspiration? Second, how does science travel? Sen's ability to push his technique onto the world stage was made possible by a Cold War culture of international travel and surgical training. Third, how do doctors judge therapeutic efficacy? Surgeons accepted Sen's operation because of their expansive physiological imaginary and their willingness to consider diverse and subjective therapeutic outcomes. Fourth, what drives therapeutic enthusiasm? Surgeons revived Sen's technique not because of new faith in the procedure but because lasers allowed them to pursue his therapeutic mission with an alluring new tool.
The Yuan dynasty marked the period of medieval China's most frequent foreign exchanges. After the establishment of the four great khanates of the Mongol Empire, the Yuan dynasty maintained close relations with the Ilkhanate, which became known as the Land of Iran. These interactions facilitated extensive medical exchanges between the two khanates. During this process, the Silk Road became a bridge for exchanging medicinal knowledge and practices between the Great Yuan and Iran. The exchange of medicines and medical prescriptions between the two was continuous, with both regions' medical practitioners adopting and applying each other's knowledge, thus bringing about a certain degree of transformative influence on their respective traditional medical systems. Based on medical and historical literature from medieval Iran and China, this study conducts a meticulous textual examination of relevant sources. This research aims to reveal an aspect of the medical exchanges between these medieval territories.
In 1912 officials in German East Africa reported that rinderpest, the most feared cattle scourge, had invaded for the first time since the 1890s African panzootic. This acknowledgment launched an expensive vaccination campaign and the creation of a veterinary infrastructure after years of neglect. Despite reports that rinderpest had been present in the region for several years, Germans nevertheless considered it an external threat, constructing disease laws accordingly. Modern virologists believe that rinderpest had been enzootic in colonial Tanzania since the 1890s, causing low mortality, afflicting animals with no prior exposure. African cattle keepers also believed the disease was the same as that of the 1890s. German resistance to recognizing rinderpest before 1912 owed to their faith in injection trials to verify a virus, and their failure to understand that enzootic rinderpest behaved differently than it did during prior epidemics. Moreover, colonial policies that traumatized animals, including landscape engineering, disease controls, wildlife slaughter, the commodifying of cattle, trade violence, and colonial warfare helped enzootic rinderpest become epidemic. The rinderpest campaign itself caused animal distress through mass vaccination and branding. While historians understand how colonial rule exacerbated human health by creating stress and compromising immunity, the same understanding has not been applied to animal health.
As in many other countries, Swedish defense during the Cold War was primarily organized around the perceived threat of war, including the potential use of nuclear weapons. This article shifts attention from such scenarios to the ways in which civil contingencies and natural disasters were conceptualized as knowledge objects within the emerging field of defense and disaster medicine. Their incorporation into Sweden's preparedness agenda signaled a broader and more multifaceted understanding of protection and security within the scientific advisory system of the Swedish defense. By centering medical knowledge production on these hazards, the article offers new insights into the role of medical expertise in Swedish preparedness, while simultaneously shifting focus away from a war-centered narrative of Cold War defense investments. The empirical exploration spans the period from the late 1950s, when a comprehensive governmental inquiry into Swedish defense medicine led to the establishment of the Delegation for Applied Medical Defense Research [Försvarsmedicinska forskningsdelegationen] and subsequently the Organizing Committee for Disaster Medicine [Katastrofmedicinska organisationskommittén] (Kamedo) in the first half of the 1960s. The study concludes in the mid-1970s, when the Delegation was incorporated into the Swedish Defense Research Establishment [Försvarets forskningsanstalt] (FOA).
