Johann Christian Schieferdecker
Slater was born the son of a cantor and organist in Teuchern. After visiting the Leipzig Thomas School, he studied at the University of Leipzig. His friend Reinhard Keiser, who also came from Teuchern, overtook him in 1702 as a harpsichordist at the Hamburg Opera House at the goose market, where he also composed. Two years later he became a pupil, then an assistant to Dietrich Buxtehude at St. Mary 's Church in Lübeck. As Buxtehude died in 1707, Slater became his successor. In this connection he had Anna Margareta Buxtehude, one of the daughters of his predecessor marry. Johann Mattheson reported that this condition himself, Handel and Johann Sebastian Bach had deterred to seek Buxtehude's successor. Slater's successor, John Paul Kunzen was.
After him the asteroid ( 7881 ) Slater was named.
From Slater's certainly extensive work very little remains. It is clear that he continued the commenced by Franz Tunder and Buxtehude firmly established at St Mary's cycle of public concerts, musical evenings. Of his works composed for the patient as Creutz- carrier Job ( 1720) or The fiery destruction of Sodom and Gomorrae (1721 ), however, only the text books available for the performances of the years 1714 to 1729. From 1707-1714, the lawyer and poet Andreas Lange was her librettist, 1716 and 1717, and it was Michael Christoph Brandenburg.
