Magnus Hirschfield (1868–1935) was a world-renowned pioneer in sexology.1 Years of his modern scientific knowledge production on sexology were monumentalized with the establishment of the Institute of Sexual Science in Berlin in 1919. On May 10, 1933, the institute became an early target of violent Nazi attacks with its library ransacked and its books burned publicly.2 During these turbulent times in Germany, Hirschfeld was on a lecture tour in the Unites States, where he was lauded as a celebrity and his knowledge was embraced enthusiastically by many in the American academy, press, and public. Unable to return home because of the Nazi seizure of power, he decided to embark on a world tour to acquire and share the “treasures of serological knowledge.”3 In transit, he acquired new ideas.
In the early years of the twentieth century, Catholic libraries in Germany adopted modernized methods of organization to simplify their use: the arrangement of books by subject, alpha-numeric classifying systems, and card catalogs. The adoption may not seem like much, but in the structure and practice of Catholic knowledge the change was fundamental. How did this revolution come about and what did it betoken?
In 1878 Moritz Daniel Oppenheim (1800–1882), probably the most famous nineteenth-century German-Jewish painter, created a work entitled The Heder, or Jewish Elementary School, which re-imagined his first school in Hanau near Frankfurt am Main in the early 1800s.
Knowledge has long garnered the attention of historians, although their explicit focus has been primarily on science, scholarship, and professional or technical expertise. For a long time, a progress-obsessed notion of society’s inexorable scientification underlay this research interest. Processes of descientification or tendencies to marginalize knowledge received little attention. This lack of attention was also apparent for those forms of knowledge that guided practical and moral behavior or that were considered religious.1
On February 10 and 11, we held a conference entitled “Mapping Entanglements: Missionary Knowledge and ‘Materialities’ across Space and Time (16th–20th centuries).” Broadly speaking, the conference posited that what we know about missionaries is not the same as what we know from missionaries, and it aimed to examine the history of the latter under the rubric of “missionary knowledge.” Accordingly, conference participants explored how missionaries produced knowledge as well as how this knowledge traveled and transformed from generation to generation and location to location. By tracing a wide variety of missionaries’ cultural productions, including writings, maps, drawings, and collections of objects, participants mapped the terrains in which missionary knowledge transpired—within, but also beyond the purview of the distinct missions in which it originated.
My year began with a session at the 131st Annual Meeting of the American Historical Association on “the dynamics of religious knowledge” in the modern era, a panel I organized with Simone Lässig. The three papers—presented by Anthony Steinhoff, Jana Tschurenev, and myself—approached developments in religious knowledge as manifestations of social and cultural change in the long nineteenth century. The studies explored a variety of religious groups in a broad array of historical configurations, from nineteenth-century Jewish religious education to the multireligious setting of Alsace Lorraine after 1870 and anticaste and feminist critiques of Hinduism in colonial India.
