Heidegger, Johann Heinrich

Heidegger, Johann Heinrich (1633-1698), Swiss theologian, was born at Bärentschweil, in the canton of Zürich, Switzerland, on the 1st of July 1633. He studied at Marburg and at Heidelberg, where he became the friend of J. L. Fabricius (1632-1696), and was appointed professor extraordinarius of Hebrew and later of philosophy. In 1659 he was called to Steinfurt to fill the chair of dogmatics and ecclesiastical history, and in the same year he became doctor of theology of Heidelberg. In 1660 he revisited Switzerland; and, after marrying, he travelled in the following year to Holland, where he made the acquaintance of Johannes Cocceius. He returned in 1665 to Zürich, where he was elected professor of moral philosophy. Two years later he succeeded J. H. Hottinger (1620-1667) in the chair of theology, which he occupied till his death on the 18th of January 1698, having declined an invitation in 1669 to succeed J. Cocceius at Leiden, as well as a call to Groningen. Heidegger was the principal author of the Formula Consensus Helvetica in 1675, which was designed to unite the Swiss Reformed churches, but had an opposite effect. W. Gass describes him as the most notable of the Swiss theologians of the time.

His writings are largely controversial, though without being bitter, and are in great part levelled against the Roman Catholic Church. The chief are De historia sacra patriarcharum exercitationes selectae (1667-1671); Dissertatio de Peregrinationibus religiosis (1670); De ratione studiorum, opuscula aurea, &c. (1670); Historia papatus (1684; under the name Nicander von Hohenegg); Manuductio in viam concordiae Protestantium ecclesiasticae (1686); Tumulus concilii Tridentini (1690); Exercitationes biblicae (1700), with a life of the author prefixed; Corpus theologiae Christianae (1700, edited by J. H. Schweizer); Ethicae Christianae elementa (1711); and lives of J. H. Hottinger (1667) and J. L. Fabricius (1698). His autobiography appeared in 1698, under the title Historia vitae J. H. Heideggeri.
