This book traces the diverse forms in which science is still popularized today back to their origins in the 19th century and situates them centrally within the bourgeois culture of that time. Contrary to long-standing prejudices, it can be demonstrated that there is a broad, vibrant, and culturally deep-rooted tradition of popular science in Germany. The focus is on the question of what significance scientific education had in bourgeois society. The development of natural history societies and school instruction, as well as the spread of a festival culture organized by scientists, are described as parts of the history of bourgeois public life, alongside the rapid increase in popular science magazines and books. It becomes clear how audience-oriented approaches evolved.
