Notker of Liège was a Benedictine monk who served as the bishop of Liège from 972 until 1008. Born around 940 to a Swabian family, he eventually became the first prince-bishop of the region after receiving the countship of Huy in 980. Throughout his career, he acted as an imperial chaplain and a diplomat, negotiating peace between the French king and Henry II. He remained a loyal supporter of Emperor Otto III, even accompanying him to Rome and participating in his funeral rites.
