From the LCMS website:
Johann von Staupitz (ca. 1469–1524), vicar-general of the Augustinian Order in Germany and friend of Martin Luther, was born in Saxony. He studied at the universities in Leipzig and Cologne and served on the faculty at Cologne. In 1503 he was called by Frederick the Wise to serve as dean of the theological faculty at the newly founded University of Wittenberg. There he encouraged Luther to attain a doctorate in theology and appointed Luther as his successor to professor of Bible. During Luther’s early struggles to understand God’s grace, it was Staupitz who counseled Luther to focus on Christ and not on himself.
