). Johannes or Hans Bach, c.1550–1626, was a Thuringian carpetweaver and a musical performer at festivals. His sons and descendants were noted organists and composers. One of his grandsons was Johann Ambrosius Bach, 1645–95, violinist, town musician at Eisenach, and father of Johann Sebastian Bach. Johann Sebastian's eldest brother, Johann Christoph Bach, 1671–1721, was organist at Ohrdruf. When his parents died he took Johann Sebastian, his youngest brother, into his home and taught him. Of the 20 children of Johann Sebastian, several were well known as musicians. The eldest son, Wilhelm Friedemann Bach, 1710–84, was made organist at the Sophienkirche in Dresden in 1733 and later (1746–64) organist and musical director at the Liebfrauenkirche in Halle.
