Saint Bruno, priest. He was born in Cologne and studied at the Reims Cathedral School to become a teacher and director of all the centers in the diocese. His legacy is two biblical comments: to the psalms and the epistles of Saint Paul.
He retired together with 6 disciples to the mountainous area north of Grenoble where later in 1084 he founded the order of the Carthusians (contemplative life and absolute silence, broken only by prayer and mass). Called by Pope Urban II to be his advisor, he reluctantly accepts, until in front of the arrival of Emperor Henry IV they flee to the countryside. In 1904 he founded his second Carthusian monastery in Calabria, near Catanzaro. The order grew until its apogee in 1510, it came to have 95 foundations to its credit; currently there are only 20. Patron of Bologna and the Papal States.
His Saint is celebrated on October 6.
