“The role of the educator is to rhythmize the soul to [moral] virtue.”1 This conclusion to his 1841 faculty address to the Königliche Realschule zu Berlin captures the spirit of Theodor Dielitz’s educational philosophy. As a teacher, Dielitz advocated systematic instruction about the real world to prepare students for a harmonious, moral life within the Prussian state.2 Beyond his classroom activities, he produced both Realschule textbooks and commercial youth-literary publications, works that he saw as complementary parts of his unified pedagogical vision. The connection between these production spheres is easy to overlook when traveling the well-worn paths of his reception as a mass-production author. Dielitz’s history and geography textbooks have long since been forgotten, but his nineteen-volume series of adventure anthologies—Images of Land and Sea (1841–1862)—enjoyed immediate and sustained success throughout the nineteenth century. It was through the Images of Land and Sea that I first encountered Theodor Dielitz.
