Hans Hefelmann was the son of a textile manufacturer from Dresden. He studied agriculture and made a career in the NSDAP. Until the end of 1942 and from March 1944, he headed the office in the Chancellery of Führer Adolf Hitler that planned and administered the murder of the sick. Hefelmann came up with the idea of disguising the murder of the sick as a railway or bus accident. He was also responsible for the operation of bogus companies that had various tasks in the murder of the sick (payroll accounting, transport). In 1945, he took over the management of a refugee camp in Stadtroda Hospital, which he knew from the »Child euthanasia« programme. He managed to escape to Argentina in 1948 via various stations (Munich, Innsbruck). He returned in 1955 and became managing director of a clothing company. Criminal proceedings initiated in 1964 were dropped. He died in Munich in 1986.
