SS physician Kurt Heissmeyer, to achieve a credentialled professorship, needed to present original research. Although previously disproven, his hypothesis was that the injection of live tuberculosis bacilli into subjects would act as a vaccine. Another component of his experimentation was based on pseudoscientific Nazi racial theory that race played a factor in developing tuberculosis.

He attempted to prove his hypothesis by injecting live tuberculosis bacilli into the lungs and bloodstream of Untermenschen (subhumans), Jews and Slavs being considered by the Nazis to be racially inferior to Germans.

He was able to have the facilities made available and to test his subjects as a result of his personal connections: his uncle, SS general August Heissmeyer, and his close acquaintance, SS general Oswald Pohl.^[7]

The medical experiments on tuberculosis infection were initially carried out on prisoners from the Soviet Union and other countries at the Neuengamme concentration camp. The experiments were then extended to Jews. For this Heissmeyer chose to use Jewish children. Twenty Jewish children (10 boys and 10 girls) from Auschwitz concentration camp were chosen by Josef Mengele and sent to Neuengamme. Mengele allegedly asked the children, "Who wants to go and see their mother?"

The children were accompanied to Neuengamme by four women prisoners. Two were Polish nurses and one was a Hungarian pharmacist, and they were killed upon arrival at Neuengamme. The fourth woman, Polish-born Jew Paula Trocki, was a doctor. She survived the war and later gave testimony in Jerusalem about what she had witnessed:

The transport was accompanied by an SS guard. There were 20 children, one female medical doctor, three nurses. The transport was in a separate carriage that was coupled on a normal train. Presented in this manner it appeared to be an ordinary carriage. We had to take off the stars of David lest we attract any attention. To prevent people from approaching us they said it was a transport of people suffering from typhoid fever... The food was excellent; on that journey we were given chocolate and milk. After a two-day trip we arrived at Neuengamme at ten o'clock at night.

— Paula Trocki^[8]

The children were injected with live tuberculosis bacilli, and they all became ill. Heissmeyer then had their axillary lymph nodes surgically removed from their armpits and sent to Hans Klein at the Hohenlychen Hospital for study. All the children were photographed holding up one arm to show the surgical incision. Klein was not prosecuted.

The collapsing western front and imminent approach of British troops prompted the perpetrators to murder the subjects of the experiment to cover up their crimes. The orders for the murders were issued from Berlin.^{[citation needed]}

The children, their four adult caretakers and six Soviet prisoners were brought by truck to the Bullenhuser Damm School in the Hamburg suburb of Rothenburgsort. The school had been taken over by the SS to house prisoners from Neuengamme used to clear rubble from the surrounding area after Allied bombing raids. The SS evacuated the building around April 11, 1945, leaving a skeleton crew of two SS guards: Ewald Jauch and Johann Frahm and a janitor. They were accompanied by three SS guards (Wilhelm Dreimann, Adolf Speck, and Heinrich Wiehagen), as well as the driver, Hans Friedrich Petersen, and SS physician Alfred Trzebinski. The children as well as others were told they were being taken to Theresienstadt. Upon arriving at the school they were led into the basement. According to one of the SS men present, the children "sat down on the benches all around and were cheerful and happy that they had been for once allowed out of Neuengamme. The children were completely unsuspecting."

They were then made to undress and were then injected with morphine by Trzebinski. They were then led into an adjacent room and hanged from hooks set into the wall. The execution was overseen by SS Obersturmführer Arnold Strippel. The first child to be hanged was so light that the noose would not tighten. Frahm grabbed him in a bearhug and used his own weight to pull down and tighten the noose. The adults were hanged from overhead pipes; they were made to stand on a box, which was pulled away from under them. That same night, about 30 additional Soviet prisoners were also brought by lorry to the school to be executed; six escaped, three were shot trying to do so, and the rest were hanged in the basement.^[9]

The children were in the care of four male prisoners, a French doctor and a chemist and two Dutch prisoners, all of whom had been imprisoned because of their anti-German activities.

The French doctor and the chemist were:

• René Quenouille (born December 6, 1887, in Lyon).^[19] He was a physician and radiologist at a hospital in Villeneuve-Saint-Georges, near Paris and a member of the French Resistance. He was arrested by the Gestapo, together with his wife, Yvonne, on March 3, 1943. Yvonne was released after three and a half months, but he was sentenced to death, although the sentence was later commuted to imprisonment.
• Professor Gabriel Florence (born June 12, 1884). He was a chemist^[20] who taught at the University of Lyon. He fought in World War I and joined the French Resistance during World War II. He was arrested by the Gestapo on March 4, 1944.

The two Dutch prisoners were:

• Anton Holzel (born May 7, 1909), who came from Deventer. He was a driver and a member of the Dutch Communist Party, who joined the Resistance after the German invasion. He became a waiter at the Novotel Den Haag, a hotel in The Hague, to facilitate the transfer of messages. He was arrested on September 11, 1941, and sent to Buchenwald. He was later transferred to Neuengamme.^[21]
• Dirk Deutekom (born December 12, 1895), who was a typographer. A member of the Dutch Resistance, he tried to hinder the deportation of Dutch Jews from the Netherlands. He was arrested in July 1941 and sent to Buchenwald, where he was given a job in the infirmary, owing to his fluency in German. On June 6, 1944, he was transferred to the concentration camp at Neuengamme.

Some of those involved in the killings were tried by a British military court in Hamburg in 1946. Trzebinski, Neuengamme commandant Max Pauly, Dreimann, Speck, Jauch and Frahm were convicted and sentenced to death. They were all hanged at Hamelin Prison on October 8, 1946.

Two of those directly responsible for the children's suffering and murder, Kurt Heissmeyer and Arnold Strippel, escaped and remained at large. Strippel had served at other concentration camps before Neuengamme, including Buchenwald. He was recognized on the street in Frankfurt in 1948 by a former Buchenwald prisoner. He was tried for the murders of 21 Jewish inmates committed on November 9, 1939, as retribution for the failed assassination of Adolf Hitler at the Bürgerbräukeller in Munich by Georg Elser. Strippel was tried, convicted of 21 counts of murder, and sentenced to 21 life terms by a Frankfurt court in 1949.^[22] In 1964, an investigation into his involvement with the Bullenhuser Damm School murders was begun by the Hamburg prosecutor's office. The statute of limitations had run out for manslaughter, so he had to be charged with murder. Among the criteria for murder, it had to be proven that the accused acted cruelly, insidiously or with motive. In 1967 the prosecutor, Helmut Münzberg, dropped the charges for lack of evidence, stating that Strippel had not acted cruelly as "the children had not been harmed beyond the extinction of their lives". In 1969, Strippel was released from prison after his other convictions were reduced to being an accessory to murder. After his release, he applied for a retrial, and in 1970 his original conviction was overturned and he was retried. At this retrial, he was convicted as being just an accessory to the Buchenwald murders and sentenced to six years' imprisonment. Because he had already served 20 years in prison, 14 years longer than this sentence, he was compensated with 121,477.92 Deutschmarks. In 1979, partly as a result of articles written by Günther Schwarberg, Strippel's case was reopened. He was not reincarcerated, and in 1987 the case was abandoned by the Hamburg prosecutor's office, owing to Strippel's frailty.^[23] Strippel died on May 1, 1994.

Kurt Heissmeyer returned to his home in Magdeburg in postwar East Germany and started a successful medical practice as a lung and tuberculosis specialist. He was eventually found out in 1959. In 1966, he was convicted and sentenced to life imprisonment. At his trial he stated, "I did not think that inmates of a camp had full value as human beings." When asked why he did not use guinea pigs he responded, "For me there was no basic difference between human beings and guinea pigs." He then corrected himself: "Jews and guinea pigs".^[24] Heissmeyer died in prison on August 29, 1967.

The building at Bullenhuser Damm was used by the British as a transit camp for German POWs until 1947. It was then used by the Hydrograpichal Institute's meteorological service until 1949, when it again became a school, for 800 boys. In 1959, the organization representing Neuengamme survivors proposed to the Hamburg school board that a memorial plaque should be placed in the school. However, it was not until 1963 that the text for the plaque was approved. The text aroused controversy because it omitted mention of the Soviet victims and did not state that the children were Jewish or give any information about their personal identity. In 1980, information signs were placed in the basement of the school, and the Senate of Hamburg (government) declared the school to be a memorial site, renaming it Janusz Korczak School: Korczak was a Polish-Jewish pediatrician and author who was murdered at Treblinka extermination camp with about 190 orphans. A rose garden was established in 1985. Later, in the Schnelsen Quarter of the city several streets were named after the children who died at the school and a memorial tablet was installed. Much of the work of identifying the victims and of bringing the story to the public's attention was due to the efforts of Günther Schwarberg.^[25]

In 2005, Wolfgang Peiner, Minister of Finance of Hamburg, published plans to sell the building. However, after several protests a spokesman denied these plans.

In 2011 a new exhibition (telling the story in German and English) was opened at the Memorial.^[26]
