Hannah Karminski did not live in the Home of the Jewish Women's Association in Neu-Isenburg for a long time. However, she is on the list of personnel of the home because in May 1938 she stayed in the institution for almost one month, probably on behalf of the Jewish Women's Association. As a close friend and confidante of Bertha Pappenheim, she often visited Neu-Isenburg.

Hannah Karminski was born on April 24, 1897, as the daughter of banker Adolf Abraham Karminski and his wife, Selma. She grew up in Berlin.

Hannah Karminski was a highly qualified social worker, trained at the renowned Pestalozzi-Fröbel-Haus in Berlin and at the Hamburg Social Education Institute of the women's rights activists Gertrud Bäumer and Marie Baum. After her education, she took over the management of the "Israelitische Mädchenclub" (Jewish Girls Club) in Frankfurt. Here, she met Bertha Pappenheim.

Bertha Pappenheim was able to convince the almost forty years younger friend to be part of the Jewish Women's Association. In the mid-1920s, Hannah Karminski returned to Berlin and took over as editor of the "Jewish Women's Association Journals for Women's Work and Women's Movement." The successful newspaper was banned in November 1938, and the Jewish Women's Association dissolved in 1939.

From the summer of 1942 onwards, Hannah Karminski directed the welfare department (which was later Care and Emigration Counseling) of the Reich Association of Jews in Germany. In this position, she helped thousands to emigrate and be saved them from deportation. She had many opportunities to leave the Nazi Germany when she accompanied children's transports to England or visited relatives in Switzerland. However, she refused to flee and leave the persecuted in Germany.

On December 9, 1942, Hannah Karminski was deported from Berlin to Auschwitz concentration camp. On June 4, 1943, she was murdered in Auschwitz-Birkenau. In the death notice from the Auschwitz camp, the cause of death is "Myocardial insufficiency."
