Peter Hasse

Peter (Petrus) Hasse (ca. 1585 – June 1640) was a German organist and composer, and member of the prominent musical Hasse family. The first written record of Hasse dates from his appointment as organist at the Marienkirche in Lübeck, a post later held by Buxtehude. Although virtually nothing is known of Hasse's early life, he is believed to have been a student of Sweelinck between 1606 and 1609.
