When HMS Beagle made its first landfall in January 1832, the twenty-two-year-old Charles Darwin set about taking detailed notes on geology. He was soon planning a volume on the geological structure of the places visited, and letters to his sisters confirm that he identified himself as a ‘geologist’. For a young gentleman of his class and income, this was a remarkable thing to do. Darwin's conversion to evolution by selection has been examined so intensively that it is easy to forget (...) that the most extraordinary decision he ever made was to devote his life to the study of the natural world by becoming a geologist. It is only slightly less astonishing that he should have decided to align his work with Charles Lyell's controversial programme of geological reform, which had almost no followers in England.

ArgumentDarwin's narrative of the earthquake at Concepción, set within the frameworks of Lyellian uniformitarianism, romantic aesthetics, and the emergence of geology as a popular science, is suggestive of the role of the sublime in geological enquiry and theory in the early nineteenth century. Darwin'sBeaglediary and later notebooks and publications show that the aesthetic of the sublime was both a form of representing geology to a popular audience, and a crucial structure for the observation and recording of the event from the (...) beginning. The awesome spectacle of the earthquake proved in turn the magnitude of the forces at stake in earth history, and helped to make geology an epic conjoining the history of civilization with the history of the earth.

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)

1990 marked the 150th anniversary of the publication of Charles Darwin's first major scientific theory. The paper, first presented by Darwin to the Geological Society of London on 7 March 1838, was entitled ‘On the Connexion of Certain Volcanic Phenomena and on the Formation of Mountain-Chains and the Effects of Continental Elevations.’ The paper was a remarkable attempt to develop a global tectonic synthesis. It was the culmination of a period of intensive geological activity by Darwin – then twenty-nine – (...) who had returned from the Beagle voyage only eighteen months previously. The present article reviews the development of Darwin's views, their impact upon his contemporaries, their role in shaping his later views on the origin of species, and their significance in scientific theory-making. It draws, in part, on Darwin's unpublished geological notes and jottings. This paper, and the papers by Sandra Herbert and James Secord that accompany it, were delivered at a symposium which I organized at the Geological Society of London on 31 October 1988 to mark the 150th anniversary of the reading of Darwin's paper.
