Widengren studied history of religions at Stockholm University for his mentorTor Andrae until 1933 and received his doctorate at the Faculty of Theology in Uppsala in 1936. His doctoral thesis was entitled "The Accadian and Hebrew Psalms of Lamentation as Religious Documents". In 1940 he became a professor of History of religions at the same faculty when he was only 33 years old.[2]
Widengren was known for having mastered many languages, which gave him an advantage in the study of the frontiers of Asia during various eras. He had studied Assyriology in Copenhagen and Iranian Studies in Uppsala for H.S. Nyberg. He mastered, among other things, Greek, Latin, Armenian, Persian, and Arabic, as well as several older Iranian languages such as Avestan and Middle Persian.
Widengren was Vice President (1950–1960) and President (until 1970) of the International Association of the History of Religion. His pupil Anders Hultgård has published In memoriam Geo Widengren (1907–1996).
Widengren emphasized the Iranian influences on Judaism, Christianity and Mithraism. Religious scholars in the 1960s critiqued these themes, but he continued to defend the importance of Iranian influence throughout his career.[3] Widengren's position was continued and developed in many works by Alessandro Bausani and Shaul Shaked.[4]
