In this publication, the reader will find some of the latest advances in this area.
The Politics of Chemistry
Agust穩 Nieto-Galan argues that chemistry in the twentieth century was deeply and profoundly political. Far from existing in a distinct public sphere, chemical knowledge was applied in ways that created strong links with industrial and military projects, and national rivalries and international endeavours, that materially shaped the living conditions of millions of citizens. It is within this framework that Nieto-Galan analyses how Spanish chemists became powerful ideological agents in different political contexts, from liberal to dictatorial regimes, throughout the century. He unveils chemists' position of power in Spain, their place in international scientific networks, and their engagement in fierce ideological battles in an age of extremes. Shared discourses between chemistry and liberalism, war, totalitarianism, religion, and diplomacy, he argues, led to advancements in both fields.
The Science of Useful Nature in Central America
In this ambitious new study, Sophie Brockmann argues that interactions with landscape and environment were central to the construction of Central American identities in the Age of Enlightenment. She argues that new intellectual connections and novel ways of understanding landscapes had a transformative impact on political culture, as patriotic reformers sought to improve the region's fortunes by applying scientific and 'useful' knowledge gathered from local and global networks to the land. These reformers established networks that extended into the countryside and far beyond Central America's borders. Tracing these networks and following the bureaucrats, priests, labourers, merchants and scholars within them, Brockmann shows how they made a lasting impact by defining a new place for the natural world in narratives of nation and progress.
A Singular Remedy
Stefanie G瓣nger explores how medical knowledge was shared across societies tied to the Atlantic World between 1751 and 1820. Centred on Peruvian bark or cinchona, G瓣nger shows how that remedy and knowledge about its consumption - formulae for bittersweet, 'aromatic' wines, narratives about its discovery or beliefs in its ability to prevent fevers - were understood by men and women in varied contexts. These included Peruvian academies and Scottish households, Louisiana plantations and Moroccan court pharmacies alike. This study in plant trade, therapeutic exchange, and epistemic brokerage shows how knowledge weaves itself into the fabric of everyday medical practice in different places.
