He is also known as one of the founders of the Provinciaal Genootschap van Kunsten en Wetenschappen in Noord-Brabant (Provincial Society of Arts and Sciences in North-Brabant), predecessor of the Brabant-Collection and the Noordbrabants Museum Hermans wrote multiple books and articles, and pioneered in several scientific fields.

In 1819 Hermans went to the minor seminary at Beekvliet manor, a Catholic boarding school in Sint-Michielsgestel.

Hermans would try to change the image of North-Brabant by studying and giving attention to its glorious history.

He acquainted Hermans with provincial official Jan Menu, and bookseller and bibliophile Hendrik Palier.

On 8 October 1835 Hermans also became a mathematics teacher at the much larger Royal School for Applied and Visual arts in 's Hertogenbosch.

[4] A third job in education was his office as schoolopziener (kind of inspector) of the first school district in North-Brabant.

In his doctoral thesis Hermans promoted the foundation of a Provincial Society for Arts and Sciences in North-Brabant.

For the latter he wanted to create a society of people who would study the language, history and antiquities of North-Brabant.

There were seven founders: C. R. Hermans; governor Baron Andreas van den Bogaerde van Terbrugge; Carel Willem Pape, minister, and headmaster of the Latin school of Heusden; Bookseller Hendrik Pallier; and Jacobus Arnoldus Mutsaers, later secretary for the Roman Catholic religion.

He published many acts, letters and others works, and in a few years, he had restored order in the city archives.

After studying old historical sources, among them the Peutinger map, Hermans found remains of the road at multiple locations in the Land van Cuijk between 1860 and 1864.

The importance of collecting scientific data like measurements, or the traces of piles, and the concept of roundels were not yet known.
