Marking Holocaust Memorial Day on Jan. 27. Opera “Spiegelgrund” premieres in Austrian Parliament

Katerina Beranova (L) and Alexandra Diesterhoeft (R) perform during the premiere of the opera “Spiegelgrund." Spiegelgrund was the name of a clinic for socially deprived children. These “anti-social” or “problem” children failed to measure up to the norm in Vienna during the Nazi dictatorship and were collected for extermination without their parents’ or caretakers’ knowledge or consent.
