Hermann Joseph was a 12th-century German mystic and Premonstratensian priest born in Cologne. A member of the nobility, he entered the Steinfeld Abbey at the age of twelve and later served as a chaplain for Cistercian nuns in Hoven. He was known for his profound devotion to the Virgin Mary, a characteristic that defined much of his spiritual life. Although he was never formally canonized through a standard process, his status as a saint was officially recognized by Pope Pius XII in 1958.
