Blessed Hermann of Reichenau or Herman the Cripple, also known by other names, was an 11th-century Benedictine monk and scholar. He composed works on history, music theory, mathematics, and astronomy, as well as many hymns. He has traditionally been credited with the composition of "Salve Regina", "Veni Sancte Spiritus", and "Alma Redemptoris Mater", although these attributions are sometimes questioned. His cultus and beatification were confirmed by the Roman Catholic Church in 1863.

The "Salve Regina", also known as the "Hail Holy Queen", is a Marian hymn and one of four Marian antiphons sung at different seasons within the Christian liturgical calendar of the Catholic Church. The Salve Regina is traditionally sung at Compline in the time from the Saturday before Trinity Sunday until the Friday before the first Sunday of Advent. The Hail Holy Queen is also the final prayer of the Rosary.
