Paul Otto Manz, was an American composer for choir and organ. His most famous choral work is the Advent motet "E'en So, Lord Jesus, Quickly Come", which has been performed at the Festival of Nine Lessons and Carols at King's College, Cambridge, though its broadcast by the neighbouring Choir of St John's College, Cambridge, in its Advent Carol Service precipitated its popularity.
His most famous organ works are his volumes of neo-Baroque chorale preludes and partitas. Paul Manz long served the church as recitalist, composer, teacher and leader in worship. He was Cantor Emeritus at the Evangelical Lutheran Church of Saint Luke, Chicago, Illinois; as well as Cantor Emeritus of Mount Olive Lutheran Church in Minneapolis, Minnesota. He was the director of the newly established Paul Manz Institute of Church Music, and was Professor Emeritus of Church Music at Christ Seminary Seminex at the Lutheran School of Theology at Chicago.
