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.
