My current book project, Artisanal Heart: Craft, Engineering, and the Culture of Knowledge in Early Modern Korea, investigates the technological knowledge of Chosŏn Korean (1392–1910) artisans and military practitioners in a global context. It emphasizes the rise of “engineers” amongst these artisans and practitioners and their system of material design and production in comparison to other early modern cultures of making and knowing. I argue that the Korean engineers developed a “technological literacy” that proved innovative across various fields, that they won recognition for doing so, and that they creatively remade global material culture, from guns and water pumps to steam engines.
