Projecting Knowledge: The Optical Lantern and Science Communication, 1880s-1940s with Dulce da Rocha Gonçalves, Nico de Klerk and Frank Kessler (Brepols, 2026)

Projecting Knowledge: The Optical Lantern and Science Communication, 1880s-1940s (Brepols, 2026) takes one of those fundamental questions - how does knowledge circulate? - and says, like others: we must look at the media technologies through which that knowledge not only circulates, but is transformed. This edited collection does that by looking at the history of the projection lantern across the late 19th and early 20th centuries.

The projection lantern, also known as the 'magic lantern', 'optical lantern', and 'sciopticon', amongst other names, is part of a long history of media technologies and techniques that have allowed users to project images onto surfaces for audiences to view. The optical lantern helped the projected image become a ubiquitous form of media, known by wide and diverse publics during a wave of 19th century media popularisation.

From the 1880s until well into the twentieth century, the optical lantern was an immensely important tool to disseminate knowledge both within and outside academia, particularly in Western Europe and the United States. This volume maps the lantern-illustrated lecture from various perspectives, with contributions on how to research historical audiences, on the spaces where projection was used, on the role of images as evidence, on the shifts in pedagogy that were supported by the projected image, and on the archives and sources that provide access to material that allows an understanding of the multiple ways in which the medium was used.

Projecting Knowledge was edited by Dulce da Rocha Gonçalves, Nico de Klerk, Frank Kessler, and Jamilla Notebaard. Dulce da Rocha Gonçalves is a historian interested in the cultural dimensions of media, science, and technology. She earned her PhD at Utrecht University within the research project Projecting Knowledge, producing the first large-scale survey of public lantern lectures in Dutch society from the late nineteenth century to the Second World War. She currently holds a postdoctoral position in the Technology, Innovation & Society group at Eindhoven University of Technology.

Nico de Klerk is an independent researcher and archivist in the field of film and media history. Between 2018 and 2023, he was a postdoctoral researcher in the project Projecting Knowledge at Utrecht University, which partly overlapped with his research for the project Educational Film Practices in Austria, 1918-1970, at the Ludwig Boltzmann Institut for Digital History, Vienna. His current research focuses on the film-illustrated lecture in the Netherlands between c. 1910 and 1940.

Frank Kessler is professor emeritus of Media History at Utrecht University. He is one of the founders of KINtop. Jahrbuch zur Erforschung des frühen Films and the KINtop – Studies in Early Cinema book series. His research interests focus on the emergence of cinema as a multi-facetted medium and a cultural form, as well as on nineteenth-century visual media. His most recent research is dedicated the optical lantern as a tool for knowledge communication.

Jamilla Notebaard is a historian whose doctoral research explored the use of the magic lantern in Dutch academic education at the end of the nineteenth century. Her work reflects a deep interest in the history of science, particularly in the epistemic role of images in shaping knowledge within scholarly communities and beyond. She investigates how visual representations function as carriers of meaning, influencing both collective understanding and individual perception.
