The self-image of the Bamberg and Würzburg Prince-Bishop Franz Ludwig von Erthal as a caring ruler was expressed in an ambitious reform program, which also included the construction of a new general hospital in Bamberg. In contrast to the traditional infirmaries, this hospital was used explicitly for the treatment of curable diseases.
Erthal's personal physician Adalbert Friedrich Marcus advanced to become a central figure in Bamberg's medical system. He headed the hospital until his death in 1816 and shaped the direction of the hospital through his openness to new medical knowledge.
The founding of the St. Getreu mental hospital also goes back to his initiative.
Marcus also promoted the good reputation of Bamberg medicine through publications such as the description of the Bamberg hospital that appeared in 1797, in which he describes its objectives and facilities.
