Werner Heyde
Werner Heyde served as medical director and first chief medical assessor of Aktion T4. The profile reconstructs the person’s function in German Reich and concentration camps incorporated into Aktion 14f13 through documented office, decisions, supervision or operational conduct. It does not assign every crime committed by an institution or region to one individual.
Confirmed findings
- Heyde served as Aktion T4's medical director and first chief medical assessor from 1939 until the end of 1941.
- He participated in the paper-based selection of patients for death and helped organise personnel, procedures and killing methods used in the programme.
- His work also extended to Aktion 14f13, through which concentration-camp prisoners were selected and murdered.
Place in the chain of responsibility
Heyde's responsibility lay in medical authorisation, institutional design and professional supervision rather than control of every local killing. The wider total for Nazi medical murder encompasses phases and institutions beyond the central programme he directed.
Key events and mechanisms
- the central phase of Aktion T4, in which more than 70,000 patients were murdered in six killing centres
- the extension of medical selection and killing to concentration-camp prisoners through Aktion 14f13
The circle records authority, function and agency. Several profiles may describe different parts of the same persecution chain, so profile-level totals must not be added together.
Postwar accountability
Heyde escaped British custody in 1947 and lived for years as Dr Fritz Sawade while working as a medical expert. He surrendered in November 1959, but died by suicide at Butzbach Prison on 13 February 1964, five days before his trial was due to begin.
Limits of the evidence
The total of more than 70,000 concerns the central Aktion T4 phase, while estimates of 250,000–300,000 cover the wider Nazi 'euthanasia' programme. Secondary sources differ over the exact place associated with his death, and no judgment was delivered.
