Franz Joseph Dölger

Franz Joseph Dölger (18 October 1879, in Sulzbach am Main – 17 October 1940, in Schweinfurt) was a German Catholic theologian and church historian.

He studied theology at the University of Würzburg, being ordained into the priesthood in 1902. Afterwards he worked as a chaplain in Amorbach and Würzburg, and in June 1904, obtained his doctorate in theology.

In the winter and spring of 1904–05, he participated in a study group to Rome, Sicily and North Africa. Later on, he furthered his education at the Campo Santo Teutonico in Rome (1908–11), followed by an appointment as associate professor of religious history at Westphalian Wilhelms-University in Münster (1911). Later in his career, he served as a professor at the universities of Breslau (1926–29; as successor to Joseph Wittig) and Bonn (1929–40).

Dölger's primary focus involved investigations of the early Christian church and its relationship with non-Christian societies.
