This stain is the only remaining trace of ten thousand people systematically gassed for the crime of having a disability by the Germans in 1941 in the gas chamber at Hadamar hospital. These persons, as well as those who followed them, murdered by medical staff using lethal injections, starvation or otherwise until well after the end of WWII, all remain nameless till this day. It is illegal in Germany to publish the names of the very first victims of the Holocaust ie. the disabled. Deprived of a life, in death, they continue to be deprived of respect, honour and remembrance.
