Viktor Hermann Brack (9 November 1904 – 2 June 1948) was a member of the Schutzstaffel (SS) and a convicted Nazi war criminal, who was one of the prominent organisers of the euthanasia programme Aktion T4; this Nazi initiative resulted in the systematic murder of 275,000 to 300,000 disabled people. He held various positions of responsibility in Hitler's Chancellery in Berlin. Following his role in the T4 programme, Brack was one of the men identified as responsible for the gassing of Jews in extermination camps, having conferred with Odilo Globočnik about its use in the practical implementation of the Final Solution. Brack was sentenced to death in 1947 and executed by hanging in 1948. Career Brack was born the son of a physician in Haaren (now part of Aachen) in the Rhine Province. In 1928, he completed a degree in agriculture at the Technical University of Munich and shortly thereafter began managing the estate attached to his father's sanatorium; he also was a test driver for BMW. In 1929 at the age of 25, Brack became a member of the Nazi Party (NSDAP) and the Schutzstaffel (SS). Throughout 1930 and 1931, Brack was one of Heinrich Himmler's personal drivers, having become acquainted with the Reichsführer-SS as a consequence of his father having delivered one of the SS leader's children. Sometime in 1932, he became adjutant to Philipp Bouhler and by 1934, Brack was his chief of staff. In 1936, he was appointed chief of Hauptamt II (main office II) in the Chancellery of the Führer in Berlin. The office handled matters concerning the Reich Ministries, Wehrmacht, NSDAP, clemency petitions and complaints received by the Führer from all parts of Germany. Aktion T4 Hauptamt II officials under Viktor Brack played a vital role in organising the killing of mentally ill and physically handicapped people in the Aktion T4 "euthanasia" programme, especially the child "euthanasia" from 1939. By a (backdated) decree of 1 September, Hitler appointed Philipp Bouhler and his personal physician Karl Brandt to manage the euthanasia program, where they would oversee the murder of physically and/or mentally disabled persons. The implementation of the killing operations was left to subordinates such as Brack and SA-Oberführer Werner Blankenburg. To efficiently accomplish this task, Brack, who headed Office II of the Führer's Chancellery created four offices; these were Office IIa or the Deputy Chief of Central Office II, headed by Blankenburg ; Office
