Saint Hugh of Grenoble

Saint Hugh of Grenoble, also called as Hugh of Châteauneuf, was born at Châteauneuf-sur-Isère, County of Albon. Even at a young age, he already showed piety and theological facility.

While still a layman, Saint Hugh of Grenoble was made a canon of Valence. In 1080, he was elected bishop of Grenoble, though he was not yet ordained. The See of Grenoble had fallen into a very poor state and Saint Hugh was selected to be its Gregorian renovator. Upon his return, he immediately set to the task of reforming the abuses in his new diocese. When he had succeeded in countering abuse and fostering devotion after two years, he tried to resign his bishopric and enter the Benedictine monastery at Cluny. However, the Pope ordered him to continue his episcopal work.

Saint Hugh was also instrumental in the foundation of the Carthusian Order. He received Bruno of Cologne, perhaps his own teacher, and six of his companions in 1084, after seeing them under a banner of seven stars in a dream. Saint Hugh installed the seven in a snowy and rocky Alpine location called Chartreuse. They founded a monastery and devoted their lives to prayer and study, being oft visited by Hugh, who was reported to have adopted much of their way of life. He also founded the nearby Monastère de Chalais, which grew into an independent order.
