Paul Gerhardt

Paulus or Paul Gerhardt (12 March 1607 – 27 May 1676) was a German theologian, Lutheran pastor and hymnodist, considered Germany's greatest hymn writer. His songs and hymns were published in contemporary hymnals such as Praxis pietatis melica, and are still part of modern hymnals. Hymn stanzas by him feature prominently in Bach's Passions and the Christmas Oratorio.
