Poetry and a large part of prose was dominated by the so-called school of ministers, as the leading writers all were or had been Calvinist ministers. As a result, many of their products emphasized Biblical and bourgeois domestic values. A prime example is Nicolaas Beets (1814–1903), who wrote large quantities of sermons and poetry under his own name but is chiefly remembered today for the humorous prose sketches of Dutch life in "Camera Obscura" (1839), which he wrote during his student days under the pseudonym of Hildebrand.
