Jacob Praetorius

Jacob Praetorius the Younger (also Schultz; 8 February 1586 – 21 or 22 October 1651) was a German Baroque composer and organist, and the son of Hieronymus Praetorius. His grandfather, the father of Hieronymus, Jacob Praetorius the Elder (died 1586), and his brother Johann were also composers. As a student of Jan Pieterszoon Sweelinck, he was one of the most important organists and most respected pedagogues of the north German tradition before Johann Sebastian Bach. From 1603 on he was organist at the Petrikirche in Hamburg.
