Johann Jakob Herzog

Johann Jakob Herzog (12 September 1805 – 30 September 1882) was a Swiss-German Protestant theologian.

Herzog was born in Basel. Herzog studied theology at the University of Basel and Berlin, earning his doctorate at the University of Basel in 1830. In 1835-1846 he was a professor of historical theology at the Academy in Lausanne. Afterwards he served as a professor in Halle, and eventually (1854), he settled at Erlangen as a professor of church history.

Herzog is remembered for his writings on the history of the Reformation (Zwingli, John Calvin, Johannes Oecolampadius), and for his studies of the Waldensian Church. Based on the encyclopedia's third edition, the New Schaff-Herzog Encyclopedia of Religious Knowledge was subsequently published in English from 1908 to 1914 (13 volumes). He died in Erlangen.
