given to the eponymous "Virchow's Method" of autopsy; the Swiss psychiatrist and neurologist Otto Binswanger, whose work in vascular dementia led to the discovery of Binswanger's Disease—so coined by his colleague Alois Alzheimer; Robert Koch, who identified the specific causative agents of tuberculosis, cholera, and anthrax; and Emil von Behring, widely known as a "saviour of children" for his 1894 discovery of a diphtheria antitoxin at a time when diphtheria was a major cause of child death (among many others). In the 20th century, at the end of the Second World War, the Charité had endured the Battle of Berlin, with Berlin having been taken by the Red Army on 2 May 1945. Though the majority of its original and pre-War structure was damaged or destroyed during the War, it nevertheless was used as a Red Army hospital. Subsequent to Victory in Europe, in the period of denazification and the Nuremberg trials, the Charité remained in the Soviet Sector of Berlin until the formation of the German Democratic Republic, the GDR—(German: Deutsche Demokratische Republik, DDR)—in 1949, more commonly called East Germany. Under the Communists, standards were largely maintained, and it became a showpiece for East Bloc propaganda during the Cold War. Corpses of Berlin Wall victims were taken here for autopsies. In 1990, with the reunification of Germany, and in the years following, Charité once again became one of the world's leading research and teaching hospitals. Organization The Charité has four different campuses across the city of Berlin with a total of 3,001 beds: Campus in Mitte, Berlin Campus Benjamin Franklin (CBF) in Lichterfelde, Berlin Campus Virchow Klinikum (CVK) in Wedding, Berlin Campus Berlin Buch (CBB) in Buch, Berlin In 2001, the Helios Clinics Group acquired the hospitals in Buch with their 1,200 beds. Still, the Charité continues to use the campus for teaching and research and has more than 300 staff members located there. The Charité encompasses more than 100 clinics and scientific institutes, organized in 17 different departments, referred to as Charité Centers (CC): CC 1: Health and Human Sciences CC 2: Basic Sciences (First Year) CC 3: Dental, Oral and Maxillary Medicine CC 4: Charité-BIH Center for Therapy Research CC 5: Diagnostic Laboratory and Preventative Medicine CC 6: Diagnostic and Interventional Radiology and Nuclear Medicine CC 7: Anesthesiology, Operating-Room Management and Intensive Care Medicine CC 8: Surgery CC 9: Traumatology and Reconstructive Medicine CC 10: Charité Comprehensive
