In December, through Spener's influence, Francke accepted an invitation to fill the chair of Greek and oriental languages in the new university of Halle, which was at that time being organized by the elector Frederick III. of Brandenburg; and at the same time, the chair having no salary attached to it, he was appointed pastor of Glaucha in the immediate neighbourhood of the town. He afterwards became professor of theology. Here, for the next thirty-six years, until his death on the 8th of June 1727, he continued to discharge the twofold office of pastor and professor with rare energy and success. At the very outset of his labours he had been profoundly impressed with a sense of his responsibility towards the numerous outcast children who were growing up around him in ignorance and crime. After a number of tentative plans, he resolved in 1695 to institute what is often called a "ragged school," supported by public charity. A single room was at first sufficient, but within a year it was found necessary to purchase a house, to which another was added in 1697. In 1698 there were 100 orphans under his charge to be clothed and fed, besides 500 children who were taught as day scholars. The schools grew in importance and are still known as the _Francke'sche Stiftungen_. The education given was strictly religious. Hebrew was included, while the Greek and Latin classics were neglected; the _Homilies_ of Macarius took the place of Thucydides. The same principle was consistently applied in his university teaching. Even as professor of Greek he had given great prominence in his lectures to the study of the Scriptures; but he found a much more congenial sphere when, in 1698, he was appointed to the chair of theology. Yet his first courses of lectures in that department were readings and expositions of the Old and New Testament; and to this, as also to hermeneutics, he always attached special importance, believing that for theology a sound exegesis was the one indispensable requisite. "Theologus nascitur in scripturis," he used to say; but during his occupancy of the theological chair he lectured at various times upon other branches of theology also. Amongst his colleagues were Paul Anton (1661-1730), Joachim J. Breithaupt (1658-1732) and Joachim Lange (1670-1744),--men like-minded with himself. Through their influence upon the students, Halle became a centre from which pietism (q.v.) became very widely diffused over Germany.
