Collects key articles by Simon Schaffer, one of the most important historians of science working today. Working Knowledge is the first English-language collection of essays by Simon Schaffer, coauthor of Leviathan and the Air-Pump, a landmark text in the history of science. Though the latter may be his most famous book, Schaffer is also renowned for seminal articles on Isaac Newton and the cultures of popular spectacle, nineteenth-century physics and its practices of labor discipline and standardization, the history of anthropology and collecting, and the globe-spanning cultural interactions that have shaped modern science. Working Knowledge compiles these well-known pieces alongside newer selections, making them accessible in a single place and representing the huge scope and impact of Schaffer's oeuvre. The Reader divides sixteen of Schaffer's articles across five thematic sections, which take up timely issues like the turn toward global histories of science; the intersection of science and capitalism; the interaction between bodies and machines; and the connection between science, politics, and the environment. Eight new essays by notable historians such as Adrian Johns, Lissa Roberts, and Steven Shapin bring Schaffer's pieces into discussion with current scholarship. Illustrations and brief commentaries by Schaffer and the artist Adam Lowe, a longtime collaborator, are included throughout the volume. Bringing together essential articles that were previously scattered across several publications, Working Knowledge is an insightful introduction to Schaffer and his ever-relevant writing.
