From the LCMS website:
Martin Luther, born on November 10, 1483, in Eisleben, Germany, initially began studies leading toward a degree in law. However, after a close encounter with death, he switched to the study of theology, entered an Augustinian monastery, was ordained a priest in 1505, and received a doctorate in theology in 1512. As a professor at the newly-established University of Wittenberg, his scriptural studies led him to question many of the church’s teachings and practices, especially the selling of indulgences. His refusal to back down from his convictions resulted in his excommunication in 1521. Following a period of seclusion at the Wartburg castle, Luther returned to Wittenberg, where he spent the rest of his life preaching and teaching, translating the Scriptures, and writing hymns and numerous theological treatises. He is remembered and honored for his lifelong emphasis on the biblical truth that for Christ’s sake God declares us righteous by grace through faith alone. He died on February 18, 1546, while visiting the town of his birth.
