Hans Lietzmann (1875-1942) was a German Protestant theologian and church historian. After studying in Jena and Bonn, he returned to Jena as Professor of Church History, before succeeding Adolf von Harnack at the University of Berlin. Among his published works are books on archaeology, manuscript history and historical theology.

Lietzmann's work stands on its own. It was the fruit of forty years' work, by an exceptionally gifted mind, on original sources connected with the progress of the early church. It is also a pioneering work in the interdisciplinary approach to this movement. . . . It remains a work for all students of the early centuries of the Christian era.
