German organist and composer. Taught first by his father and Andreas Crappius, from 1609 through the end of 1612 he studied with Sweelinck in Amsterdam. His first known post was as organist of the Wolfenbüttel Hauptkirche from 1623 through 1626 before becoming court organist to Christian IV in Copenhagen from 1626 through 1629. In 1629 he succeeded his father as organist of the Marktkirche in Hannover, remaining there until his death.
Schildt was a founder of the so-called North German organ school, and one of its most original composers. Almost all of his surviving music is for keyboard, and most of that Chorale-based organ works. His only extant vocal work is the chorale concerto Ach mein herz-liebes Jesulien.
