First they killed the "crazies" and "cripples" : the ableist persecution and murders of people with disabilities by Nazi Germany 1933-45 : an anthropological perspective

The Nazis not only initiated their campaign to systematically persecute and murder people with disabilities in the earliest days of their regime; the murders continued during and even after World War II had ended. Yet, knowledge about this aspect of Nazi atrocities has not permeated the dominant cultural consciousness to any appreciable degree. While the facts of these crimes and murders do not represent new information as such, the accounts that do exist show an abiding lack of clarity as to the underlying prejudices toward people with disabilities that allowed the murders to occur. Today disabled survivors are rarely recognized or compensated. Most of the history of these events has been done in the field of Holocaust studies.
