performed almost 60,000 autopsies in which he compared the patients' medical history and clinical symptoms with their autopsy protocols. He recognised that physicians named illnesses after the most conspicuous external symptom without considering the underlying internal disease of the organs (e.g. diagnosing jaundice in patients who presented with yellowish skin with no thought given to the underlying liver disease). It became clear to him that these symptomata, (which in Greek means coincidences) are not coincidences but in fact external indications of a pathological change to an internal organ. In close collaboration with the internist Joseph Škoda he made clear the relationships between clinical symptoms that can be seen, felt or heard and pathological changes to organs, i.e. clinico-pathological correlation. Thus it was now possible for the first time to make scientifically sound diagnoses. Rokitansky thus initiated a paradigm shift from speculative, natural-philosophical medicine to systematic, science-based medicine. By classifying illnesses according to their stage of progression, it became possible to diagnose how far a pathological condition had advanced and to deliver a prognosis. From the 1830s onwards medical students and physicians from all over the world came to Vienna to learn about Rokitansky's diagnostic methods and nosology, which soon became known internationally as the Young or New Viennese School. The systematic investigation of each individual organ led to the development in Vienna of new clinical disciplines. Rokitansky also supported this development in his role as a medical advisor to the Minister of the Interior as well as the establishment of the world's first clinic for otology. As a pathologist and philosopher, Rokitansky thought about patients holistically and was vehement in his demands that patients with psychological disorders, back then called "lunatics" also had the right to a diagnosis, treatment and healing. He therefore demanded the establishment of the first University Clinic of Psychiatry in Austria. In his application, he wrote that the clinic should be headed by Theodor Meynert. The importance subsequently given to the psyche paved the way not only for Sigmund Freud, psychology and psychoanalysis, according to Eric Kandel it also influenced modernist art which turned its gaze below the surface appearance of things and placed the depiction of its models' emotions in the foreground. Manual of Pathological Anatomy: Rokitansky documented the results of his research in his three-volume Handbuch der pathologischen Anatomie published in 1842–46 by Braumüller & Seidel. He systematically described pathological changes to each and
