Hergenrother, Joseph von (1824–1890)

German theologian and historian. His Anti-Janus (1870), defended the doctrine of papal infallibility. He was made a prelate of the papal household in 1877, a cardinal in 1879, and curator of the Vatican archives. He also wrote Photius, Patriarch von Konstantinopel/Photius, Patriarch of Constantinople (1867–69), and Katholische Kirche und Christlicher Staat/Catholic Church and Christian State (1872), a book on the relations of church and state. His other works include a universal church history and a history of the papal states since the Revolution.
