. Almost immediately, by September, Rijeka fell under German control. On 21 March 1944, betrayed by an acquaintance, Germans arrived up at the Perlow home and arrested the family, including Gisella, Sergio (then aged 6), and seven other family members, including his cousins (photo) Andra (6) and Tatiana Bucci (4). The latter would ultimately be the youngest Italian survivors of the Holocaust. The Perlow family was taken to the

concentration camp and immediately joined the group of deportees leaving on 29 March and arriving in Auschwitz after six days in by convoy. Gisella and Sergio survived the first selection and Sergio was assigned with his cousins in the Kinderblock (Children's hut). Sergio's cousins Andra and Tatiana Bucci were with Sergio, had begun to understand German and had been warned that the guards could exploit the children's greatest vulnerability: they would line up the children and ask those who wanted to see their mother to step forward. In this way, the experimenters could easily walk their subjects away without resistance. The sisters had warned Sergio, but with a single step he had unknowingly volunteered as one of Joseph Mengele's human subjects. The cousins would survive.


Neuengamme experimentation

Having been chosen in November 1944 by Joseph Mengele as one of the twenty children (10 boys and 10 girls) to be sent to the Neuengamme concentration camp, Sergio was made available as a human subject in Kurt Heissmeyer's

, the Netherlands, Yugoslavia, and Poland, arrived at the Neuengamme concentration camp, Neuengamme concentration camp, accompanied by Dr. Paulina Trocki and three nurses. In Neuengamme the children were entrusted to four deportees, charged with taking care of the group: the French doctors, René Quenouille and Gabriel Florence, and two Dutch nurses, Anton Hölzel and Dirk Deutekom. For several weeks the children experienced a period of relative calm; the experiment required their good health. On 9 January 1945 Heissmeyer began the experiments: he had the skin on the chest of 11 children, under the right armpit, incised with X-shaped cuts, three to four centimeters long, to introduce tuberculosis bacilli with a spatula — causing rapid spread of the disease. In early March the children, sick and feverish, were operated on to remove their axillary lymph nodes, which according to the doctor's theories should have produced antibodies against tuberculosis.

document the operations; they show each child, shaven and shirtless, presenting their raised arms and their under-arm incisions. The experiment had failed: the removed lymphatic glands were sent to Hans Klein, a pathologist at the Hohenlychen clinic, who on 12 March 1945 certified to Heissmeyer that no antibodies had been generated. Before leaving the extermination camp on 17 January 1945, the Schutzstaffel, German SS burned all possible evidence attesting to what happened in Auschwitz-Birkenau. Sergio's name appears in a rare exception, a medical report, one of the few documents not destroyed. The document, dated 14 May 1944, confirmed the presence of the children of Bullenhuser Damm.


Bullenhuser Damm Massacre

By the time his experiments failed and news traveled that the Allies of World War II, Allies were fast approaching, Heissmeyer had fled. The camp commander Max Pauly was left to deal with the children. On the evening of 20 April, orders came directly from Berlin to eliminate all trace of what had transpired in Neuengamme. At 10pm on the evening of 20 April, the children, their four adult caretakers and several Soviet prisoners were loaded into a mail truck and driven the approximately 30 kilometers from the Kinderblock hut 4a, the site of the experimentation, to Bullenhuser Damm — along with Wilhelm Dreimann, Adolf Speck, Heinrich Wiehagen, their executioners, so-called SS doctor Alfred Trzebinski and Johann Frahm, German SS sergeant. Johann Frahm, German SS sergeant at Neuengamme concentration camp and deputy camp commander at the Neuengamme satellite camp on Bullenhuser Damm, reported on 2 May 1946: Eleven months later at the British Curiohaus Trials in Rotherbaum in March 1946, Trzebinski testified: The massacre ended at dawn on the morning of April 21, with the killing of eight other Russian prisoners. The bodies were brought back to the Neuengamme concentration camp and cremated.


De Simone Family aftermath

Sergio's parents, Eduardo De Simone and Gisella Perlow De Simone survived the war. Sergio's mother had also been deported to Auschwitz and sent in the spring of 1945 to the Ravensbrück concentration camp, where she was released. Gravely ill, she was only able to return to Italy in November 1945 and reunite with Eduardo, who after 8 September had also been deported to the Dortmund labor camp in Germany. Thirteen members of Gisella Perlow's family had been apprehended before the war; four survived. His parents had searched for news of Sergio, only learning in the late 1940s that their son had been transferred from Auschwitz to another camp. Gisella and her husband would have another son, Mario De Simone, born in 1946. In the 1980s, around the time the story of the Bullenhuser Damm Massacre began to emerge, Sergio's mother began receiving letters from Hamburg, dismissing them because she didn't read German. In 1983, after the death of Sergio's father in 1964, his mother was informed of the massacre. Mario De Simone later related that on learning of the atrocities, his mother — who had clung to the possibility of Sergio's survival — was deeply affected; her entire affect changed. She attended the memorial ceremony on 20 April 1984 in Hamburg and died in 1986, less than two years from learning of the Neuengamme experimentation and the Bullenhuser-Damm Massacre. Sergio's younger brother continues to advocate for human rights. In 2019, he said "my brother was murdered because he was compromising evidence." Sergio's two cousins, sisters Anda and Tatiana (Tati) Bucci, survived and were initially relocated to Lingfield in England via Prague. In 2020, the sisters authored their story ''Storia di Sergio'' with Alessandra Viola. His two cousins describe Sergio's death "like a boulder that weighs inside us."


Legacy

In April 1946 the main material perpetrators of the massacre, including Commander Max Pauly, who gave the final orders, were tried by an English court and sentenced to death, carried out in October 1946. Although the responsibilities of Kurt Heissmeyer were brought to light in the trial, the German doctor was not indicted because he was not present at the massacre; he would continue his medical career unimpeded. Though a small group of ex-Neuengamme fellow prisoners continued to bring flowers each year to Bullenhuser Damm, collective memory of the massacre itself had almost been lost. After 1945, the Bullenhuser Damm building reopened as a school, without mention of the basement massacre. In 1959, German journalist Günther Schwarberg published a series of articles dedicated to the massacre in the weekly Stern (magazine), Stern, implicating Heissmeyer. The reopening of the trial in 1963 led to Heissmeyer's life sentence in 1966. He died of a heart attack the following year in Bautzen prison. Obersturmbannführer Arnold Strippel, the highest-ranking Nazi criminal involved in child murder, was sentenced to life imprisonment in 1949, but was released in 1969 and even received around 120,000 marks in compensation. He died a free man in 1994. With his wife, attorney Barbara Hüsing, Schwarberg began the task of identifying and tracing the relatives of the murdered children, creating in 1979 the ''Association of the Children of Bullenhuser Damm.'' From 1979, the association
Children of Bullenhuser Damm
' underwrote the memorial for the victims of the massacre, until it was transferred to municipal sponsorship in 1999 and became a branch of the Neuengamme concentration camp memorial. In 1980 (expanded in 2010–11), the cellar at the Bullenhuser Damm School was made a Holocaust museum, where the other children and adult victims of the massacre are commemorated.


Hamburg-Schnelsen

In 1991, 20 streets in the Schnelsen Burgwedel district of Hamburg were named after the children, including a street near Wassermann Park ''Sergio De Simone Stieg'', as well as a kindergarten, playground, and park. The park, Wassermannpark, is named after the eight-year old Polish victim, known only as H. Wassermann. Wassermannpark was completed in 1995, includes 28 hectares of water features, cycle paths, picnic areas, and playgrounds. Roman-Zeller-Platz is named after one of the 20 children of Bullenhusen Damm. A masonry stele was erected on 13 July 2001, with a bronze relief of children by Russian artist Leonid Mogilevski (1931-). The stele was an initiative by, and paid for by, Hamburg citizens with underwriting by Kunststiftung Heinrich Stegemann. Citizens of Hamburg attend the commemoration ceremony on 20 April every year.

La Stella by Andra and Tati

Presented on 13 April 2018 in Turin, the animated feature ''La Stella by Andra and Tati'' was dedicated to the deportation of the Bucci sisters, Sergio's two cousins, to Auschwitz — becoming the first European animated film on the Holocaust. Focusing on his two cousins, the feature includes Sergio, up until he was separated from his cousins. Debuting on the occasion of the 80th anniversary of the fascist racial laws in Italy, the 30-minute film, directed by Rosalba Vitellaro and Alessandro Belli, was presented at the International Animation Festival on the Bay, held in 2018 in the Piedmontese capital.
