Vienna buries victims of Nazi medical experiments President Heinz Fischer, Vienna Mayor Michael Haeupl, the president of the Jewish community Oskar Deutsch and Dorothee Stapelfeldt, deputy mayor of Hamburg, Germany - where several victims came from - attended the ceremony, alongside survivors and relatives of the victims. The remains, belonging mostly to children and adults who were patients at the mental hospital Am Steinhof, were uncovered during recent research into Nazi-era activities. During the Second World War, some 3,500 patients at the facility overlooking Vienna were killed, most often by systematic negligence, exposure to cold and undernourishment, as well as deliberate contagion with infectious diseases, according to official sources. Among the victims were some 780 children and teenagers, whose remains were still used for years after the war for medical and scientific purposes. In 2002, the first remains from over 600 children were buried at the Zentralfriedhof in a section dedicated to Nazi victims. A monument is also planned at the site to honour the victims of Nazi medical experiments in Viennese institutions. To remember and commemorate, that's what we can do for the victims. To tackle our past," Haeupl said at Wednesday's ceremony, a day after the 67th anniversary of the end of the Second World War in Europe. The psychiatric hospital Am Steinhof was set up in the early 1900s and still exists, although it has since been renamed.
