Vienna: The Nazis called them "unworthy lives" people they considered physically or mentally inferior to the Aryan ideal set by Adolf Hitler and used them for gruesome medical experiments.
Today, nearly 70 years after their deaths, and after the end of research into how they were killed, Vienna ceremonially buried the last known remains of such victims who had died in city institutions.
After tributes by dignitaries, a Vienna Central Cemetery worker placed an urn into a small grave flanked by red and white funeral wreaths. President Heinz Fischer invoked the memory of those "who fell victim to a horrible medical killing machine."
Before being confiscated after World War II, the remains were owned by Heinrich Gross, a Nazi-era doctor.
