Blurb: Tuberculosis as a chronic infectious disease seems to sit oddly with common notions of what is to be considered epidemic or endemic. As a result, the conditions presence is often endemic in character, but the term itself is rarely employed. However, the question of an epidemic or endemic character was explicitly addressed was in studies of African tuberculosis between the world wars. Around 1930, researchers were exploring its presence in Africa, and many were favouring Lyle Cummins’ hypothesis that, much like European colonisation, the condition was a recent arrival in Africa. This meant that there had to be a quickly spreading epidemic into a susceptible population. In my paper, I will look at the epidemiological surveying that was done in Northern Tanganyika in exploration of Cummins’ theory. What does it teach us about colonial science? What happened to Cummins’ explanation when available data – as they were – supported it less and less?

Biography: Christoph Gradmann is professor of the history of medicine at the University of Oslo, Department of Community Medicine and Global Health.

Blurb: Why were some regions hit much harder by COVID-19 than others—and how new was this geography of mortality? In this talk, I will examine regional excess mortality during the pandemic in 2020 and 2021 across more than 500 regions in France and Europe, highlighting which areas were most affected and how spatial patterns evolved over time. I will then compare these recent patterns with four major mortality crises of the 20th and 21st centuries: the Spanish flu, the 1911 and 2003 heatwaves, and the Hong Kong flu. Using harmonized regional mortality data from the French Human Mortality Database, I will explore how the magnitude and spatial structure of excess mortality during COVID-19 fit within a longer historical continuum of longevity shocks.

Biography: Florian Bonnet is a tenured researcher at the French Institute for Demographic Studies (Ined). His work lies at the intersection of demography, economics, history, and geography, with a focus on the long-term evolution of social and spatial inequalities in longevity and economic development in France and across Europe. He combines historical data reconstruction with spatial and statistical analysis to uncover how regional disparities in mortality and living standards have emerged, persisted, and transformed over time.

Blurb: A large body of social science and health research uses measures of the 1918 influenza pandemic’s mortality to estimate what the biosocial effects of the pandemic were. However, many of the pandemic measures used in this research either exhibit very high rates of error; are systematically correlated with pre-pandemics determinants of the effect of interest; or are a poorly chosen estimand for testing the causal chain of interest. Additionally, even though pandemics have wide-ranging impacts on society, many existing studies do not attempt to rule out plausible alternate channels linking the pandemic to the effect of interest. Each of these four methodological problems can produce false negative results, false positive results, and false positive results of the incorrect sign. We illustrate the extent of these problems using a series of helpful case studies from the 1918 context. In doing so, we make methodological contributions that stress the importance for causal research on pandemic of conducting sensitivity analyses on the calculation of excess mortality, accounting for omitted variable and collider bias, and measuring pandemic severity for the most theoretically appropriate time period and point-of-view.

Biography: Hampton Gaddy is a PhD researcher in demography and economic history at the London School of Economics and an affiliate at the Leverhulme Centre for Demographic Science at the University of Oxford. He works primarily on the 1918 influenza pandemic, the determinants of its mortality, and its social consequences.

For the second Pandemics & Society Seminar of our Fall 2025 series we are pleased to welcome Max Marczinek (University of Oxford). The seminar will be held on Thursday, 25 September at the normal time (1600 CEST). More information about our speaker and the presentation is below. You can sign up for email notifications about the seminar series, including the Zoom details, here.

Blurb: In this webinar, Marczinek will present a paper studying the relationship between labour scarcity and productivity in the context of a 1710s plague outbreak. While higher wages should have led to an export contraction, exports grew after plagued regions shifted into capital-intensive production. Using a Ricardian model, he show that productivity growth in capital-intensive sectors is best suited to explain this export boom. Marczinek argue that labour scarcity incentivises capital-intensive production which raises productivity growth.

Biography: Max Marczinek is a 4th year PhD student in Economics at Oxford University. His research studies trade, labour, and economic history. He combine trade models with novel and often historical data sources, using theory to extract new insights from granular data.

For the first Pandemics & Society Seminar of our Fall 2025 series we are pleased to welcome Robert Braid (University of Montpellier).

Abstract: This paper integrates the findings of psychology and behavioral economics in order to understand better an historical phenomenon. After the Black Death, a plague epidemic which wiped out roughly 40% of the population, the historical data runs counter to all economic theory that would predict an increase in productivity and higher real wages. Peasants inherited the most fertile lands and had larger farms, yet grain yields fell. Capital (tools, windmills, livestock, carts, etc.) per capita increased tremendously but productivity fell. Commercial infrastructure and public administration remained intact, but trade dropped off. There was an acute shortage of labour yet real wages stagnated. Although climate factors may account for some of these trends, they don’t explain all, leaving economic historians of this period perplexed. This study argues that the Black Death caused trauma in survivors, altering levels of biochemicals leading to increased agitation and lack of attention in some and disengagement in others, similar to the behavior of victims of PTSD. Chroniclers and other observers recorded a number of behavior patterns among survivors which suggest that the Black Death was a deeply traumatic event which affected their ability to work. These findings are also consistent with the historical data on productivity and may also shed light on the increased levels of civil unrest in the post-plague era.

Biography: Robert Braid is Assistant Professor at the Faculty of Economics of the University of Montpellier (France), and member of the Center for Environmental Research – Montpellier. He focuses on the origins of economic regulations across different western European regions, in particular in the 13th and 14th centuries. Most of his work has been dedicated to understanding the psychological, social and economic impact of the Black Death which gave rise to a broad wave of unprecedented economic regulations seeking to constrain the demands of workers and retailers. He has also worked on the medieval scholastic literature that attempts to give a moral framework both for economic agents and for rulers who seek to regulate their behavior, and how this literature changed soon after the plague. He has also worked on wage theory and the history of economic thought in general.

Abstract

The late Michael Dols has produced much valuable research on the topic of plague outbreaks in Mamluk Middle East. Paradoxically – and with the exception of Stuart Borsch’s work on the Black Death in Egypt — the topic remains under-investigated, with many questions unanswered. The proposed paper will focus on the question: When and how was plague imported into Egypt and how did it spread over its territories, in the later Mamluk period. Did Egypt have its own plague reservoir, as claimed by some 18^th– and 19^th-century writers, both Western and Egyptian? Or was it imported from elsewhere? If so, from where and by what means? And how would plague spread within Egypt, once imported on ships or on camelback? To answer this questions, the paper will rely on a wide array of sources – first and foremost, Mamluk chronicles, but also other, hitherto unutilised materials, including pilgrims’ travelogs, and correspondence of Italian merchants, , notaries, travellers and diplomats (often overlapping categories). Taken together, these sources connect together pieces of puzzle, thus revealing some fascinating insights into the questions above. Although dealing with a later period compared to other conference papers, its methodology, findings and conclusions may appear instructive to scholars and scientists of earlier plague/ infectious diseases in Egypt, for which much less source material survives.

Abstract

Long Covid is an old story linked to a new virus. Chronic Lyme. Chronic Fatigue Syndrome. Chronic Pain. These contested conditions are interpreted with trepidation—in many cases throughout history they have been considered unreal or imagined among medical professional: a cry for help from a hysterical woman. Though, their prominence is patterned throughout history and takes center stage in famous literature, social science, and medical humanities. Because women are centered as those most afflicted by these conditions, they have become largely feminized and dismissed, regardless of who they are. Yet, the long history of symptoms that are defined as “unexplained” or “complex” or “contested” tell us more about medicine than they do about people. These symptoms may be physical—such as pain in the back, extremities, or the base of the neck. They may be psychological—such as dissociation, brain fog, or lack of focus. They may be emotional—such as deep sadness or anxiety. It is important to listen to these complex bundles of symptoms and try to decipher them: not only through the arc of someone’s life but also a cultural history through which they have emerged, shifted, and transformed. In this talk, I track this history, beginning with hysteria, and leading us to the present-day.

Abstract

This talk explores the COVID-19 pandemic in the Global South, and highlights why context matters in understanding pandemics. I will discuss two key aspects: (1) the demographic challenges that low- and middle-income countries (LMICs) face in responding to pandemics and epidemics, with a focus on older populations, and (2) how the COVID-19 pandemic reshaped overall levels of mortality and the age structure of causes of death in an LMIC. This presentation invites you to rethink pandemic preparedness and impact beyond the high-income framework.
