Bruno, Saint (1040-1101), the founder of the Carthusian Order. He was born and educated at Cologne, and at Rheims was appointed rector of studies in the schools of the diocese. In 1084 he retired with six companions to a mountain solitude near Grenoble, where he and they entered upon a life of great strictness, living in cells apart, and only meeting upon Sunday. The rule they adopted was that of St. Benedict. In 1089 he was summoned to Rome by Pope Urban II., who had been his pupil, and preferment was offered him, but he declined all honours, and withdrew to Calabria, in whose solitudes he founded the monastery of "the tower" (Della Torre), where he died. His canonisation was in 1514.
