German priest Johannes Quasten (1900–1987) was a theologian and scholar of patristics. He was a professor at the Catholic University of America for thirty years, until his retirement in 1979. The Quasten Medal—the only academic award given by CUA’s School of Theology and Religious Studies—is named after Father Quasten.
Quasten published more than one hundred books and articles and is best known for his four-volume Patrology, a standard reference in the field of patrology.
