Heinrich Scheidemann (c. 1595 ? 1663) was a German organist and composer. He was the best-known composer for the organ in north Germany in the early to mid-17th century, and was an important forerunner of Dieterich Buxtehude and J.S. Bach. He was born in Wöhrden in Holstein. His father was an organist in both Wöhrden and Hamburg, and probably Scheidemann received some early instruction from him. Scheidemann studied with Sweelinck in Amsterdam from 1611 to 1614, and evidently was one of his favorite pupils, since Sweelinck dedicated a motet to him at the end of the time, prior to Scheidemann's return to Germany. By 1629, and possibly earlier, Scheidemann was in Hamburg as organist at the Catharinenkirche, a position which he held for more than thirty years, until his death in Hamburg in early 1663 during an outbreak of the plague.
