Sacer, Gottfried Wilhelm—1635-1699—a native of Naumburg, who was at his death an advocate and privy-counsellor at Wolfenbüttel, distinguished in his official duties by a strict conscientiousness, and the most unbounded benevolence. He wrote the greater number of his hymns whilst a student at the university of Greifswald. Only a part of them appeared during his life-time: they were collected and published in 1714, and immediately procured him the reputation of a distinguished poet.
