T4 Memorial: Visit the Brandenburg Euthanasia Memorial

The Memorial for the Victims of Nazi Euthanasia Murder

The short answer

The Memorial for the Victims of the Euthanasia Murders, at Nicolaiplatz 28/30 in Brandenburg an der Havel, stands where the Nazis gassed more than 9,000 sick and disabled people in 1940, at one of the six killing centres of the Aktion T4 programme. The town is about an hour west of Berlin on the RE1 train. The exhibition is open Thursday to Sunday, the outdoor memorial at all times, and admission is free. Allow one to two hours. Berlin’s own T4 memorial, at Tiergartenstraße 4 by the Philharmonie, is a separate site.

The story · by Matt Robinson

Of the numerous memorials for the victims of National Socialism that can be found a short distance from the current German government quarter, it is that next to the Berlin Philharmonic building which serves to commemorate the first group to have suffered at the hands of the Nazis on a genocidal level. A translucent sky-blue wall and corresponding curved metal sheet, the fourth memorial introduced to the city for the victims of Adolf Hitler’s murderous regime, stands for the disabled, the mentally handicapped – the so-called life unworthy of life (Lebensunwertes Leben). The main Berlin commemoration for the victims remembered at the Brandenburg T4 Euthanasia Memorial.

Here on the Tiergartenstrasse (number 4) once sat the administrative headquarters of the organisation responsible for the Aktion T4 plan to exterminate anyone considered physically or mentally incompatible with the National Socialist Weltanschauung.

While the paperwork and preparation would be carried out in Berlin – the implementation of this strategy of industrial murder would take place elsewhere – in hospitals, psychiatric clinics and six secret killing facilities – such as the T4 euthanasia clinic in Brandenburg an der Havel. For the Nazis, the knowledge gathered as a result of this murderous policy would prove fundamental in preparing the way for the further industrial killings in the East – of perceived racial enemies of the so-called Third Reich.

A paper trail of murder

Meticulous bureaucracy would define the mass killings carried out by the National Socialist regime, leaving a paper trail of documents to be analysed and surveyed by generations to come. As such it is possible to chart the trajectory followed over the course of the development of the Nazi extermination programmes.

By examining the medical killings carried out under the auspices of the Aktion T4 plan, it is also possible to gain valuable insight into the duplicitous mindset of the Nazi doctrine – where the institutionalised mass murder of a segment of society deemed a burden on the whole would be perversely justified: as a merciful death to relieve the suffering of individuals tormented by their own imperfections. A process of state sanctioned euthanasia in a country where outright murder still remained clearly illegal – as premeditated killing continued to carry with it a death sentence for the perpetrator according to German criminal law.

During the initial phase of the programme’s operation, from 1939 until 1941 (when Aktion T4 was interrupted due to public outcry), some 70,000 people are known to have been murdered – although it is estimated that up to 200,000 in total would fall victim to this policy, as work continued discreetly and out of the public eye until the end of the Second World War.

Graduating from the killing facilities of Bernburg, Brandenburg, Hadamar, Hartheim, Grafeneck, and Pirna-Sonnenstein, the programme would finally reach into the concentration and extermination camps with the help of the team of physicians originally tasked with these centrally-planned euthanasia murders.

The killing centre at Nicolaiplatz

Originally constructed in part of a penitentiary complex, the facility at Brandenburg an der Havel was established in 1939 on the site of an earlier concentration camp, closed five years earlier.

Its location in the centre of this small town, at the Nicolaiplatz, meant that its existence was well known to the local inhabitants. In fact, opposition to the facility, and the T4 programme, would grow as the smoke from the mobile furnaces used to burn the bodies of murdered patients would spread across the town – choking the historic centre of Brandenburg with one of the real and undeniable consequences of this callous policy. A lesson the Nazis learned that would influence the construction of later extermination camps, whereby they would be located far from urban areas and away from any population that might find fault with their purpose or practice.

The Brandenburg T4 Euthanasia Memorial here now contains a museum documenting the historical foundations of Nazi euthanasia and racial hygiene policy utilising the testimonies of people who were involved. The biographies of some 30 victims have also been recreated on the basis of photographs and documents donated by their families.

The first gas chamber

Beyond serving as one of the first killing facilities of the Aktion T4 programme – this location also bears the unfortunate distinction as the site of the first Nazi gas chamber on German soil.

Many of the men, women, and children, targeted as ‘life unworthy of life’ would be poisoned by morphine-scopolamine injection or slowly starved to death, but as the need to speed up the killing process increased, further methods were tested to establish greater efficiency. Asphyxiation by carbon monoxide eventually proved to be the most viable alternative, whereby following a short medical examination patients would be led to a gas chamber to be murdered en masse.

The foundation of the former prison barn where the gas chamber had been installed is still visible at the present day site.

As this refined killing process would be introduced to other killing facilities, the newly acquired expertise of the physicians and nursing staff – trusted members of society, expected to uphold an ethical code of decency and humanity to care for the sick and needy – would further fuel the pursuit of National Socialist racial goals. As medical professionals became professional killers and killing professionals – and the T4 Euthanasia site in Brandenburg an der Havel was reduced to just one of many locations where the National Socialist Weltanschauung reached its atrocious zenith.

The Brandenburg killing centre in detail

How the killing centre worked

From October 1939, asylums across Germany had to fill in a registration form for each patient: diagnosis, length of stay, and above all whether they could work. Assessors working for the T4 office at Tiergartenstraße 4 in Berlin decided on life or death from these forms alone, without ever seeing the patient. Those marked for death were collected in buses run by a front company, the ‘Charitable Patient Transport Company’, often via transit asylums so that their families lost track of them.

Brandenburg was disguised as a ‘state nursing home’ (Landes-Pflegeanstalt). New arrivals were undressed, briefly examined and photographed, then led into a gas chamber built to look like a shower room in the old prison barn, where carbon monoxide from steel cylinders killed them. The bodies were burned. Families received a letter of condolence, an urn and a death certificate with an invented cause and date of death.

The doctors who ran it

In January 1940 the killing method was tried out here in a ‘test gassing’ watched by about fifteen men, among them Philipp Bouhler, head of Hitler’s private Chancellery, Hitler’s escort physician Karl Brandt, the Reich health leader Leonardo Conti and the young Austrian doctor Irmfried Eberl. From 1 February 1940 Eberl ran the centre under the false name ‘Dr Schneider’. The exhibition names 70 of its staff: doctors, nurses, policemen, SA and SS men, clerks and kitchen staff.

In October 1940 the centre closed and its staff moved on to Bernburg. Several later served in the extermination camps of Operation Reinhard; Eberl became the first commandant of Treblinka in 1942. Bouhler killed himself in May 1945. Brandt was sentenced to death at the Nuremberg Doctors’ Trial and hanged on 2 June 1948, and Eberl hanged himself in custody the same year.

The few who objected

Open protest was rare, and one of the bravest came from this town. Lothar Kreyssig, a guardianship judge at the Brandenburg district court, noticed that the disabled people in his care were dying in suspicious numbers. On 8 July 1940 he wrote to the Reich Minister of Justice, Franz Gürtner, and he filed a criminal complaint for murder against Bouhler. Gürtner told him that a judge who could not accept the will of the Führer as law could not remain a judge. Kreyssig was suspended in December 1940 and forced to retire in 1942. He survived the war, founded Action Reconciliation Service for Peace in 1958 and was named Righteous Among the Nations in 2016.

What finally stopped the gassings was public unease, voiced most loudly by the Catholic Bishop of Münster, Clemens August von Galen, in his sermons of summer 1941. On 24 August 1941 Hitler ordered the programme halted. The killing went on by starvation, drugs and neglect until 1945.

    Take the A10 and A2 west and leave at Brandenburg an der Havel, or follow the B1 through Potsdam. The memorial’s website gives no parking information; there are public car parks by Nicolaiplatz.

What you’ll see

  • The permanent exhibition, opened in August 2012 in a former outbuilding of the old prison: the roots of Nazi ‘racial hygiene’, how the killings were organised, the victims, about 30 of their life stories, the 70 named staff and what happened to them after 1945.
  • The memorial book, with the names of more than 8,200 identified victims, and the outdoor stelae with photographs of men, women and children murdered here.
  • The place of remembrance on the site of the prison barn, where the gas chamber was disguised as a shower room: its brick foundations are laid out in gravel, and only the rear wall survives.

Tips from a guide

  • Check the day before you travel: the exhibition opens only Thursday to Sunday, though the outdoor memorial can be seen at any time.
  • The RE1 stops in Potsdam on the way back, so the trip combines well with an afternoon at Sanssouci or Cecilienhof.
  • Groups can book a 90-minute guided tour in English or German (€30 for up to 30 people; minimum age 15) on +49 3381 7935-113, also outside opening hours.
