Johann Martin Chladenius

He was the son of Martin Chladenius (1669–1725), a professor of theology at Wittenberg University. He attended the Casimirianum Gymnasium in Coburg and enrolled in 1731, at the Wittenberg University, where he received his master's degree in philosophy, and taught after his studies. He went to the University of Leipzig, where he became an associate professor of church antiquities in 1742.

In 1743 he took over the management of the Casimirianum in Coburg and was appointed full professor of theology, rhetoric, and poetry at the University of Erlangen in 1747, where he received his doctorate in theology during the same year. Although he was not originally trained as a historian, he nevertheless made a name for himself with his philosophically sound and pragmatic didactic theory of history.

As a theologian, he orientated himself towards Lutheran orthodoxy, which he sought to combine with the rationalism of Christian Wolff and empiricism. In historiography, he was the first to interpret historical sources according to a hermeneutic method. He opposed the representatives of historical Pyrrhonism and introduced the concept of the “viewpoint”, from which historical reality could be viewed from multiple perspectives. With this interpretative approach, Chladni is regarded as one of the first methodologists of hermeneutics and modern historical research.[2][3]
