Helga Löwenberg was given to the care of "Heim Isenburg" in December 1939 at the age of 14. She lived there for about two years until the dissolution of the institution.

Helga had grown up in Wiesbaden together with her mother Zerline, her older half-brother Kurt and younger brother Karlheinz (see Rink, p. 54 ff. for the following). The mother was Jewish; her father was obviously not Jewish. Helga first attended a state school in Wiesbaden. From 1938 onwards, she was forced to attend the Jewish community school in Mainzer Straße. The family was poor since Zerline Löwenberg had to raise her three children by herself as an unskilled worker. She initially lived in Adlerstraße. According to the notification sheet of the City of Neu-Isenburg, Helga moved to Wiesbaden, Romberg 14. Before her deportation, the family was sent to a small room with access to a kitchen in a ghetto house in Wiesbaden, Ludwigstraße.

On March 29, 1942, Helga Löwenberg was deported from Neu-Isenburg to Kassel. However, she returned to Wiesbaden from there because only two and a half months later, on June 11, 1942, she was deported from Wiesbaden to the Lublin district together with her mother and her younger brother Karlheinz.

The deportation of the Wiesbaden Jews described by Willy Rink:

"On the morning of June 10, 1942, the 371 Wiesbaden Jews who had been destined for deportation were picked up at their homes by trucks, taken to Wiesbaden main station, and loaded on the provided train. After a short stay in Frankfurt where more wagons were loaded with 618 Frankish Jews and 264 Jews from rural districts in “Regierungsbezirk Wiesbaden.” The train did not go to Theresienstadt as many of the 1,253 deportees had believed but rather to Lublin in Poland. There, the deportees who had survived the harsh transport were subjected to a selection at a railway ramp near the "Old Airfield" in Lublin. About 200 men between the ages of 15 and 50 who were considered fit to work were segregated and used to build the nearby Majdanek concentration camp. All the women, children, and the rest of the men were driven back into the wagons and the train, DA 18, drove the victims to the Sobibór extermination camp near Lublin (Rink, p. 91)”

The older men, women, and children probably stayed in the Izbica Ghetto for a few days before they were transported to Sobibór.

16-year-old Helga Löwenberg, her 41-year-old mother Zerline and her 10-year-old brother Karl Heinz were murdered at the Sobibór extermination camp. Survivors from this transport are not known. Helga’s half-brother born in 1923, Kurt Josef, had already died on December 28, 1941, at the age of eighteen, in Groß-Rosen concentration camp.

According to Nazi legislation, Helga and Karlheinz Löwenberg were so-called "half Jews" because only one parent was of Jewish origin. As "half Jews" they would have been somewhat protected from the deportation if they had not belonged to the Jewish community of Wiesbaden. The first ordinance of the "Reich Citizens Act" (Nuremberg Racial Law of September 1935) § 5 (2) states:

"As a Jew from two Jewish Grandparents as well a Jewish half-breed,

A) Belonging to Jewish religious community, the [...] applies."

By this law, Helga and Karlheinz Löwenberg were treated as "full Jews," persecuted and murdered.:
