Am Spiegelgrund clinic

Am Spiegelgrund was a children's clinic in Vienna during World War II, where 789 patients were murdered under child euthanasia in Nazi Germany. Between 1940 and 1945, the clinic operated as part of the psychiatric hospital Am Steinhof later known as the Otto Wagner Clinic within the Baumgartner Medical Center located in Penzing, the 14th district of Vienna.

Am Spiegelgrund was divided into a reform school and a children's ward, where sick and disabled adolescents were unwitting subjects of medical experiments and victims of nutritional and psychological abuse. Some died by lethal injection and gas poisoning; others by disease, starvation, exposure to the elements, and "accidents" relating to their conditions. The brains of up to 800 victims were preserved in jars and housed in the hospital for decades.

The clinic has gained contemporary notoriety, due to publications concerning Hans Asperger and his association with the patient selection process in the Children's Ward.
