Then, at the age of fifteen, the Benedictines awarded him 900 Guilders to study in Rome, where he attended at the Accademia di San Luca under Sebastiano Conca[1] and, from 1713-14, lived in a room attached to the workshop of the sculptor Pierre Le Gros the Younger.

In 1725, he was appointed court painter by Anselm Reichlin von Meldegg [de], the Prince-abbot.

At St. Lorenz Basilica in Kempten, he painted the St. Nikolaus Dome and Benedict's Chapel in 1736 and returned in 1748 to create five oval altarpieces.

[3] In the State Rooms of the Fürstäbtliche Residenz (a monastery complex), he painted the ceilings and walls as well as portraits of former Prince-abbots in the Residence Hall.

[1] Overall, very few major religious structures within a twenty-mile or 30 km radius of Kempten are without frescoes, altarpieces or other works by Hermann.
