Today’s saint is Saint Wolfgang of Regensburg:
Saint Wolfgang of Regensburg (c. 934 – October 31, 994) was bishop of Regensburg in Bavaria from Christmas 972 until his death. He is a saint of the Roman Catholic and Eastern Orthodox churches (canonized in 1052). He is regarded as one of the three great German saints of the 10th century, the other two being Saint Ulrich and Saint Conrad of Constance.
Saint Wolfgang lived an eventful life. He was a missionary, a bishop, a religious reformer, a tutor of royalty and at the end of his life became a hermit. More can be read about him at his wiki, found here.
