In 1891 Théodore Flournoy (1854-1920) 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 (retired in 1944)
and Edmond Rochedieu (retired in 1965) 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.
