The Euthanasia trials (German: Euthanasie-Prozesse) were legal proceedings against the main perpetrators and accomplices involved in the "euthanasia" murders of the Nazi era in Germany.
The first euthanasia trial was held by the United States in October 1945 to prosecute doctors and nurses at the Hadamar killing centre for the murder of Polish and Russian workers sick with tuberculosis in summer 1944. All seven defendants were found guilty, and three were executed. Euthanasia was a tangential issue at the Nuremberg Doctors' Trial, held by the United States from December 1946 to August 1947, as only four of its twenty-three defendants were charged with participation in the euthanasia programme: Karl Brandt, Viktor Brack, Waldemar Hoven, and Kurt Blome. Brandt, Brack, and Hoven were convicted, sentenced to death, and executed; Blome was acquitted.
There was a euthanasia trial held in the Soviet occupation zone in Dresden in June 1947 to prosecute those who had worked at the Sonnenstein Euthanasia Centre in Pirna. There were 15 defendants, including Paul Nitsche, the director of the T4 Medical Office (German: Medizinische Abteilung). Four of the defendants, including Nitsche, were sentenced to death and executed.
