as a surgeon and lacked the experience, as well as the supplies and instruments necessary to operate on battle victims, he nonetheless assisted in major surgical operations. During these surgeries, Schenck was aided by Dr. Werner Haase, who also served as one of Hitler's private physicians. Although Haase had much more surgical experience than Schenck, he was greatly weakened by tuberculosis, and often had to lie down while giving verbal advice to Schenck. By 28 April, the emergency casualty station was in desperate need of medical supplies. During the battle, Schenck went out in a Wehrmacht truck into Berlin to obtain medical supplies to bring back to the casualty station. Upon returning to the emergency casualty station, Schenck resumed his surgical duties. In the seven days they worked together, Schenck and Haase performed some "three hundred and seventy operations". He later recalled the terrible conditions and experience, after the war, to author/historian James P. O'Donnell. During the end time in Berlin, Schenck saw Hitler in person twice, for only a brief time: once when Hitler wanted to thank him, Haase, and nurse Erna Flegel for their emergency medical services, and once during the "reception" after Hitler's marriage to Eva Braun. During the early morning of 1 May 1945, Haase took Schenck aside while at the emergency casualty station to tell him that Hitler was dead. Schenck was later taken prisoner by the Soviet Army during the attempted Berlin "break-out" of 1 May. Following their surrender, Schenck, Wilhelm Mohnke and other senior German officers from the group were treated to a banquet by the Chief of Staff of the 8th Guards Army with the permission of Lieutenant General Vasily Chuikov. At 10:30 pm, the Germans were ushered out into another room where they were confined under guard. On the following night of 3 May, Schenck and the rest of the Germans were handed over to the NKVD. Schenck was released from Soviet captivity in 1953 and returned home to (then) West Germany. There he worked at Chemie Grünenthal (now Grünenthal GmbH). Prior to writing his memoirs, Schenck was interviewed in depth by O'Donnell for the book The Bunker, which recounted portions of Schenck's memories of Hitler's last days. The possibility that Hitler suffered from Parkinson's disease was first investigated by Schenck. He published his opinions and findings in a book, Patient Hitler. Eine medizinische Biographie, in 1989. Schenck died on 21
