According to the biography by Razo Bonvisinus, a contemporary and prior of Steinfeld Abbey, at the age of seven Hermann attended school and very early was known for devotion to the Blessed Virgin.

[1] According to still another legend, on another occasion, when on a cold day he made his appearance with bare feet, Mary procured him the means of getting shoes.

Late in his life, he had under his charge the spiritual welfare of the Cistercian nuns at Hoven [de], near Zülpich, whom he served as chaplain.

[3] He possibly created the oldest hymn to the Sacred Heart of Jesus ("Summi regis cor aveto").

His feast, however, continued to be celebrated on 4 April, by the members of his Order and the name of Hermann was listed in the Premonstratensian supplement to the Roman Martyrology.

Pope Benedict XIII consecrated an altar in honour of the Blessed Hermann Joseph in the Roman College of the Norbertines in 1728.

(The Salvatorian Fathers, who had come to occupy the abbey in Steinfeld in modern times, opted to perform this less costly and involved process—known as Confirmatio Cultus—rather than to carry out a full canonization process.)

Hermann Josef is depicted as a religious with Mary and the baby Jesus, often offering an apple; his attributes are a chalice or three roses.

The patronage of expectant mothers ("patronus puerperarum") has been handed down since the 17th century in the use of "touch relics", such as needles, brooches and clasps left on the reliquary and retrieved to fastened to their hairstyle or clothes in the hope of a happy pregnancy through the intercession of the saint.
