In 1891 Thέodore Flournoy became the first Professor of Psychology to be appointed at the University of Geneva, and his teaching regularly included references to religion. His successor, Georges Berguer, who taught psychology of religion, began as privat-docent in 1910 and received a full professorship in Religious Psychology and the History of Religion in 1928. French-speaking Switzerland is one of the rare places in the world where psychology of religion has been taught continuously since the very beginning of the (...) 20th century. The aim of this article is to shed light on this tradition and especially on Georges Berguer and Edmond Rochedieu who succeeded Flournoy. This historical enterprise concludes with some reflections on the role of the psychology of religion at the intersection of psychology and the study of religions. (shrink)
