The theologian and pedagogue Gerhard Bohne (1895-1977) wrote in the 1950s a study titled 'The Piety of the Child', in which he investigates how a child becomes pious and how piety evolves during childhood. Now this study is published for the first time as a critical edition and will become an important resource for historical educational research and provides an insight into the evolve of religious pedagogy/education of the 1950s.
