    The Kaufbeuren District Hospital is a specialist psychiatric clinic in Kaufbeuren in Bavaria. During the National Socialist era, the predecessor institution, Heil- und Pflegeanstalt Kaufbeuren-Irsee, was involved in the murder of numerous patients at its locations in Kaufbeuren and Irsee in the course of "euthanasia". The then director of the Kaufbeuren main station and its branch, Valentin Faltlhauser, was an active advocate of the killing of mentally and physically impaired people.

    After the National Socialists came to power and numerous ordinances, the “Heil- und Pflegehaus Kaufbeuren-Irsee” was actively involved in the euthanasia killings of mentally and physically impaired people between 1939 and 1945. Its significance for the murders of the sick under National Socialism lay primarily in the fact that the institution, with 1.200 beds, was already the largest facility of its kind in Swabia in the 1930's. Since September 1939, people from all over Bavaria have been transferred to the Kaufbeuren-Irsee asylum.

    Action T4

    At the beginning of 1940, the director Valentin Faltlhauser received a list for the first time with the names of those patients who were to be transferred to specific imperial institutions in the course of the T4 campaign and who were to be killed there with gas. A total of 687 patients were transported to the Grafeneck and Hartheim killing centers between August 26, 1940 and August 8, 1941 and murdered there. With the end of the T4 campaign and the end of the transports, the Kaufbeuren-Irsee sanatorium carried out the killings of the adults and children themselves.

    "Starvation of patients"

    The "withdrawal diet" used in a targeted manner was the continuation of the T4 action that had been canceled. In Bavaria, the state welfare associations had been pushing for a reduction in accommodation costs since the late 1920's. Even before the beginning of the war, Valentin Faltlhauser advocated dieting for patients based on work performance. In Irsee, the "hungry diet" had therefore been used since August 1942 and in Kaufbeuren since October 1942. On November 30, 1942, Walter Schultze signed the “Hunger Food Decree” on behalf of the Bavarian Ministry of the Interior, according to which all “unable to work” patients were undernourished and exhausted due to malnutrition. The majority died from the resulting deficiency symptoms or from corresponding secondary diseases. The food given contained no carbohydrates, no fat, no meat and only little bread. The change in meals significantly increased the death rate in the institution during these years.

    Tuberculosis experiments

    The senior physician at the Mittelberg children's sanatorium, Georg Hensel, carried out medical experiments on physically and mentally impaired children at the Kaufbeuren-Irsee sanatorium between 1942 and 1944. In order to find a vaccine against tuberculosis, Hensel, in consultation with Valentin Faltlhauser, vaccinated at least 13 children a self-developed vaccine. The medical experiments were fatal for six of the children.

    Liberation by US troops

    American troops occupied Kaufbeuren at the end of April, but did not yet intervene in the institution's operations. It was not until July 1, 1945 that the rumors about the infanticide reached the military office, whereupon three soldiers and a photographer broke into the institution and stopped the killing. In the months after the end of the war, the Allied troops described the liberated institutions and the doctors involved in a report. This report by the American intelligence service bears the handwritten title “Medical extermination camp in Kaufbeuren, Bavaria” and was probably not far from the truth, as the following description shows:

    “Almost every inhabitant knew exactly that people there were being used as guinea pigs and systematically slaughtered. The perpetrators or passive contributors were in no way aware of their crimes, they were Germans, not Nazis. There were also Catholic sisters among them. The head nurse, who admitted to having killed 'about' 210 children by intramuscular injections in two years, simply asked: 'Will something happen to me?' The stinking corpses of men and women were found in an unrefrigerated morgue who had died twelve hours to three days earlier. They weighed between 26 and 33 pounds. Among the children still alive was a ten-year-old boy who weighed less than 10 kilos. And whose legs were 6 centimeters in diameter at the ankles. Dr. Valentin Faltlhauser, 69 years old, Chief Medical Officer since 1919, was the director and was arrested. Also Franziska Vill, secretary to Dr. Faltlhauser was arrested. His deputy Dr. Lothar Gärtner, 43 years old, and who had been employed since January 1, 1930, committed suicide by hanging himself with the cord of a bedside lamp. Three other doctors were also arrested".

    Ernst Lossa's death certificate
    Ernst Lossa's death certificate

    Ernst Lossa was born in Augsburg on 1 November 1929. His father, Christian Lossa, belonged to the Yenish minority and earned his living as a travelling tradesman. His mother, Anna, died from pulmonary tuberculosis on 24 September 1933, when Ernst was only three years old. He had two sisters, Amalie and Anna, and a younger brother named Christian.

    The Yenish were regarded by the Nazi regime as socially and racially undesirable. Ernst’s father was imprisoned in Dachau Concentration Camp between 1936 and 1938. According to Amalie, he had been taken into so-called “protective custody” after confronting an SS man. With their mother dead and their father imprisoned, Ernst and his sisters were placed in a children’s home in Augsburg-Hochzoll. Amalie later recalled that they were frequently insulted and discriminated against because of their family background.

    Institutionalisation

    On 15 February 1940, ten-year-old Ernst was transferred to a youth institution at Markt Indersdorf near Dachau. The authorities described him as “uneducable” and accused him of stealing food, running away and taking a bicycle. Although assessments recognised that Ernst possessed normal intellectual abilities and a clear mind, his behaviour was increasingly interpreted through the racial and psychiatric prejudices of the period.

    His difficulties adapting to institutional life were treated not as the understandable behaviour of a vulnerable child separated from his family, but as evidence of an alleged permanent character defect. A psychiatric assessment declared him “unfit for the community” and portrayed his stealing as a supposedly congenital compulsion. Such labels had no legitimate medical foundation. They transformed poverty, trauma and disobedience into reasons for continued confinement.

    Ernst was not institutionalised because he had a serious psychiatric illness. He was condemned because Nazi society considered his background and behaviour undesirable.

    On 20 April 1942, Ernst was transferred to the Kaufbeuren sanatorium and nursing home. Staff members later remembered him as an intelligent, lively and good-natured boy. He continued to take things, but witnesses recalled that he sometimes stole food to give to patients who were starving.

    Kaufbeuren-Irsee

    Kaufbeuren-Irsee was the largest psychiatric institution in Swabia and became deeply involved in the Nazi murder of disabled and mentally ill people. Under director Valentin Faltlhauser, patients were deliberately killed through lethal medication, neglect and systematic starvation.

    These murders continued after the centralised phase of Aktion T4 had officially ended in August 1941. Unlike the six central Aktion T4 killing centres, Kaufbeuren-Irsee did not operate a gas chamber. Patients were instead murdered individually or allowed to die slowly through starvation and deliberate medical neglect.

    On 5 May 1943, Ernst was transferred to Kaufbeuren’s branch institution at the former Irsee monastery. By then, he appears to have understood that patients around him were being deliberately killed.

    His awareness of the murders, combined with his refusal to conform and his attempts to help other patients, may have contributed to the decision to kill him.

    The Murder of Ernst Lossa

    During the night of 8–9 August 1944, Ernst was told that he would receive an injection against typhus. Instead, while he was sleeping, nurse Pauline Kneissler, acting on the orders of institution director Valentin Faltlhauser, administered a lethal injection of morphine-scopolamine in the presence of male nurse Paul Heichele. Ernst struggled against death for several hours before dying on 9 August 1944. He was fourteen years old.

    His official death certificate concealed the murder by recording bronchopneumonia as the cause of death. Ernst’s medical file described him using the degrading Nazi psychiatric label “asocial psychopath,” presenting the deliberate killing of a healthy child as the natural consequence of an illness. Ernst Lossa was not murdered because he was incurably ill. He was murdered because the Nazi state had decided that a poor, institutionalised Yenish boy who refused to conform had no place in its imagined racial community.

    Ernst’s murder later became important evidence in post-war investigations into the crimes committed at Kaufbeuren-Irsee. His story is now one of the best-known individual examples of the decentralised killings that continued in psychiatric institutions after the official suspension of Aktion T4.

    Persecution Disguised as Medicine

    Following the Nazi seizure of power, disabled people and others classified as “hereditarily diseased” became targets of state persecution. The Law for the Prevention of Hereditarily Diseased Offspring, enacted in July 1933, led to the forced sterilisation of hundreds of thousands of people. The persecution subsequently escalated from compulsory sterilisation to systematic murder. Children and adults with disabilities, psychiatric conditions or socially undesirable backgrounds were transported to killing centres, starved, neglected or deliberately poisoned with overdoses of medication.

    Ernst’s life reveals how Nazi racial ideology, social prejudice and corrupted medicine worked together. A child who had lost his mother, been separated from his family and subjected to years of discrimination was transformed by bureaucratic language into a supposed danger to society and ultimately murdered by the people responsible for his care.

    Today, the former Irsee institution houses the Schwäbisches Bildungszentrum Irsee. A Stolperstein outside the former monastery and annual commemorations preserve Ernst’s memory and that of the other patients murdered there.

    1948, a courtroom in Germany, psychiatric nurse Pauline Kneissler, is on trial. A witness testifies against her. He says, “Pauline greeted me very warmly. And one comes away saying, ‘Oh, that’s a fine nurse. She’s taking splendid care of my mother.” But, he said, “In doing so she was the murderer of my mother.” Pauline Kneissler was found guilty of this murder, and hundreds more. She murdered her patients willingly.

    Trial

    The Frankfurt Regional Court sentenced the nurse Pauline Kneissler to four years and the nurse Paul Heichele to twelve months in “penitentiary”. The two nurses Mina Wörle (1895 - 1973) and Olga Ritter (1901 - 1979) received 18 and 21 months in prison. The Frankfurt Higher Regional Court confirmed Kneissler's sentence on October 20, 1948 for murder and aiding and abetting. In 1949, the case against those responsible in Kaufbeuren took place in Augsburg. Ernst Lossa's death played an important role in the trial. On July 30, 1949, Valentin Faltlhauser was sentenced to three years imprisonment in at least 300 cases for inciting aiding and abetting manslaughter. The prison sentence, however, was never carried out after several postponements due to incapacity and a pardon by the Bavarian Minister of Justice in 1954.

    In court, Faltlhauser stated that Lossa had been relocated to Kaufbeuren for the purpose of "euthanasia". His death was ordered by the Reich Committee for the Scientific Registration of Hereditary and Constitutional Serious Ailments.

    A nurse of the Kaufbeuren institution testified that she had to kill children on Faltlhauser's orders. As a rule, luminal tablets were given dissolved in tea, only in isolated cases by injections. The patients died after two to three days. Morphine scopolamine injections are said to have only been given to particularly restless children in isolated cases. The dose was determined by Faltlhauser himself.

    Together with four other members of the Kaufbeurer prison staff, Faltlhauser was charged with involvement in euthanasia crimes before the Augsburg regional court. The subject matter of the proceedings included “participation in the 'euthanasia program' by transporting the mentally ill to the killing centers, as well as participating in the killing of adult and adolescent patients using luminal tablets, morphine scopolamine injections and inadequate nutrition”. In July 1949, Faltlhauser was sentenced to three years in prison for inciting aiding and abetting manslaughter. After repeated postponement of the execution of the prison sentence because of incapacity to custody, the pardon by the then Bavarian Minister of Justice  and the re-approval of the pension, which had meanwhile been canceled, took place in December 1954.

    After the war, Faltlhauser justified his behavior with a sense of duty, compassion and social consensus.  As a civil servant, he was brought up to obey the respective orders and laws.

    “In any case, my actions did not occur with the intention of a crime, but on the contrary permeated with the consciousness to act mercifully towards the unfortunate creatures, with the intention of freeing them from a suffering for which there is no salvation with the means known today to act as a true and conscientious doctor. "

    Due to the decades of discussions about euthanasia, he assumed a social consensus and therefore did not doubt the justification of Hitler's “euthanasia” decree.

    Letter by Adolf Hitler authorising the killing of the "incurably sick" by means of a "mercy death".

      On the current site of the Swabian Education Center Irsee there are three memorial sites dedicated to the victims of Nazi euthanasia:

      On November 22, 1981, a monument by the Allgäu artist Martin Wank was erected on the institutional cemetery used between 1944 and 1972. Another memorial plaque, which was installed in 2009, is located at the entrance to the prosecution. Also in 2009 the artist Gunter Demnig let three stumbling blocks in front of the Irsee Monastery and in September 2015 seven more stumbling blocks.

      There are three more monuments in the city of Kaufbeuren:

      In 1989 the employees of today's district hospital initiated the erection of a three-tonne memorial in front of the hospital's Thomas Church. Since 2006 there has also been a monument by the Irsee artist Peter R. Müller at the former prison cemetery. In 2008, a group of students from Kaufbeuren schools erected a memorial in front of the youth center in Kaufbeuren, which among other things is dedicated to the memory of the victims of the Nazi regime.
