Humboldtian Science and Humboldt's science

This article investigates why Humboldtian Science, as a heuristic concept, has gained prominence in the historiography of science and requires clarification. It offers an ideal-type model of comparative research and exact measurements across vast spaces, which Susan F. Cannon and others tied to Alexander von Humboldt (1769-1859). Yet, he himself was less "Humboldtian" than this concept suggests. The article proposes to disentangle Humboldtian Science from Humboldt's science, which constituted a set of individual research practices that defied the ideal of precision. Humboldt's science was often impromptu, marked by epistemological and personal insecurities, and embedded in the protagonist's peripatetic way of living and frequently erratic writing style. Historicizing Humboldt's science undermines the exceptionalism that elevates the Prussian savant above his contemporaries and casts him as a singular figure. This critical reflection encourages biographical approaches to the history of science, balancing heuristic generalizations and attention to individual research styles.
