In 1843, Johann Kaspar Jakober, a practising doctor, took over the running of the spa until 1881, unfortunately with ever decreasing success – despite the development of the main access road. After his death some years later, it was his daughter who turned the Spa into a public inn, gaining a dubious reputation in the process. The church council ordered that card games be forbidden at Wilerbad, and only cider and branz were allowed to be served.
