Within the historiography of early modern science, trust and credibility have become synonymous with genteel identity. While we should not overlook the cultural values attached to social hierarchy and how it shaped the credibility of knowledge claims, this has limitations when thinking about how contemporaries regarded the origins of that knowledge and its location in different types of workers and skillsets. Using the example of seamen in the circles of the Royal Society, this article employs the category of experience, and (...) by extension expertise, to illustrate how recognized forms of knowledge and skill acted as routes to credibility and authority in early modern science. It argues that, within the experimental community, the seaman’s authority derived from their direct experience of novel and remote phenomena and the cumulative effect of their wider experience. The accumulated experience they acquired from frequent practice, observation, and exposure translated into a form of “expertness” that rendered seamen trustworthy and credible observers and thinkers. The gentlemanly trust model does not accommodate nor acknowledge the ways the seaman’s direct and accumulated experience (and that of many other professional groups) were recognized and valued in inquiry and discourse. The article therefore sets out a new model for understanding trust, credibility, and authority in early modern science that can take us beyond a restrictive mono-model that locates trust in one sociocultural category to highlight the multiple, and sometimes competing, claims to epistemological authority.

The history of climate research in the 20th century has been characterised by a crucial shift from a geography-oriented, two-dimensional approach towards a physics-based, three-dimensional concept of climate. In the 1930s, the introduction of new technology, such as radiosondes, enabled climatologists to investigate the high atmosphere, which had previously been out of reach. This “conquest of the third dimension” challenged the surface-oriented, geographical notion of climate patterns and opened up climatology to a three-dimensional approach, which deeply changed the character of (...) climate research. Two decades later, by drilling deep into polar glaciers and using the downward vertical dimension as an archive of the earth's history, ice core scientists began to reconstruct past climates layer by layer. The data retrieved in deep glacial layers contributed crucially to a temporal expansion of climate history far beyond human timescales. However, the inaccessibility of glaciers and the practical challenges of bringing fragile fragments of ice into transnational networks of scientific exchange meant that this vertical extension of climate knowledge production proceeded through a range of new scientific practices, and was shaped by new forms of international collaboration. Furthermore, this vertical approach to glaciers also asked for a new understanding of glacier volume. Drawing on archival and printed sources, I argue that ice core research represented a second discovery of the third dimension, this time downwards into the depth of the earth's surface, but again with decisive consequences for the research practice, for collaboration politics, and for understandings of climate, spatially as well as temporally.

Summary From summer 1792 until spring 1797, Alexander von Humboldt was a mining official in the Franconian parts of Prussia. He visited mines, inspected smelting works, calculated budgets, wrote official reports, founded a mining school, performed technological experiments, and invented a miners’ lamp and respirator. At the same time he also participated in the Republic of Letters, corresponded with savants in all Europe, and was a member of the Leopoldine Carolinian Academy and the Berlin Gesellschaft Naturforschender Freunde. He collected minerals, (...) made geognostic observations, performed chemical and physiological experiments, read the newest scientific journals, and prepared and published texts on mineralogy, geognosy, chemistry, botany and physiology. Humboldt did his scientific investigations alongside his administrative and technical work. This raises the question of whether there were fruitful interactions between Humboldt's technical-administrative work and (parts of) his natural inquiry. I argue that the mining official Humboldt was a late eighteenth-century figure of hybrid savant-technician. Mines and smelting works provided numerous opportunities for studies of nature. Humboldt systematically used inspection tours for mineralogical and geognostic observations. He transformed mines into chemical laboratories, and he transferred knowledge and material items from his natural inquiries in mines to academic institutions. The main objective of this paper is to illuminate the persona of savant-technician (or scientific-technological expert) along with Humboldt's mixed technological and scientific work during his term as mining official.

This article looks into mining in central Germany in the late eighteenth century as one area of highly charged exchange between science and the state. It describes bureaucratic knowledge as socially distributed cognition by following the steps of a high-ranking official that led him to discover a rich silver ore deposit. Although this involved hybridization of practical/artisanal and theoretical/scientific knowledge, and knowers, the focus of this article is on purification or boundary work that took place when actors in and around (...) the mines consciously contributed to different circuits of knowledge production. For the sake of analysis, the article suggests a way of opposing bureaucratic versus scientific knowledge production, even when the sites, actors involved in, and practices of that knowledge production were the same or similar. Whereas the science of the time invoked consensus among equals to conflate competing knowledge claims, bureaucracies did so by applying a hierarchy among ranked individuals. (shrink)

After the Seven Years War, the Prussian administration launched a campaign for useful knowledge and scientific education of state officials. This essay scrutinizes efforts undertaken around 1770 by the Central Prussian Administration for Mining and Smelting Works to establish the “mining sciences” and a mining school in the city of Berlin. As a result, from October 1770 on this Administration supported the public teaching in Berlin of mathematics, mechanics, mineralogy, metallurgy, chemistry and other areas of knowledge that constituted the “mining (...) sciences.” In so doing, it promoted the interconnection of scientific and technological knowledge. Contrary to common belief, however, a mining school or academy was not established in eighteenth-century Berlin. (shrink)

ArgumentBetween 1878 and 1880, Switzerland, Italy, and Japan initiated the world's first national earthquake commissions, but only the Swiss made ordinary citizens a vital part of this undertaking. This paper examines the texture of communication between Swiss scientists and lay observers and traces the development of a language for seismology that was simultaneously scientific and vernacular. This is the story of an aborted dialogue between scientists and citizens about living with environmental risk, an alternative abandoned on the way to the (...) increasingly technical science of the twentieth century.

By resituating Alexander von Humboldt in the “working world” of mining, this essay offers a case study of the way in which industry has shaped practice and theory in the history of science. While Humboldt’s experience as a miner in Saxony and Prussia provided him a venue in which to study fossilized vegetation, revealing a fundamental link between the migrations of plants and of peoples, industrial concerns about miners’ safety inspired a study of the interplay between plants and people that (...) shaped his later articulation of the verticality of plant distribution. Moreover, the cartographic methods Humboldt employed during his American journey depended as much on drawing practices indebted to mining as they did on patterns of vertical mobility above and below the surface of the earth. These arguments ultimately encourage a departure from “Humboldtian Science,” a term that has veiled an originally Prusso-Saxon science beneath a set of Anglo-American connotations. (shrink)
