Róza was born and raised in Ciechanów, Poland. In November of 1942, her family was deported to Auschwitz and Róza was the only one who was not gassed on arrival. She was selected to work in the Bekleidungskommando in the Birkenau area of the camp, which had the job of sorting the confiscated belongings of the prisoners and the murdered. Róza put together a resistance group that distributed news that members of the camp's underground had obtained by listening to radio broadcasts in secret. Eventually Róza found out about a revolt that the men in the Sonderkommando were planning, and recruited a number of other women to help out. She contacted Ala Gertner, Hanka and Ester (Estusia) Wajcblum, Hadassah Zlotnicka, Ruzia Grunapfel, Marta Bindiger, Inge Frank, Regina Safirsztajn, Genia Fischer, and a number of other women who were working in the Union Munitions factory, which made rocket parts for V2s. The particular room of the factory these women worked in was the only place in Auschwitz where inmates had access to gunpowder. The women would set aside a small amount of gunpowder each day, at great personal risk to themselves, and smuggle it back to Róza, who in turn passed it along to Asir-Godel Zilber, who was from her hometown. The smuggling chain continued until it made its way to a group of Sonderkommandos who assembled it into bombs and grenades. It took over a year for them to smuggle enough gunpowder to make the revolt and attempted escape a reality. On 7 October 1944, Crematorium IV was blown up, although the uprisings in the other crematoria were put down before they were able to get that far. In retribution for what had happened, every third Sonderkommando was shot. An investigation into how this could have happened went on for weeks, and the gunpowder was finally traced back to the Union Munitions factory. All of the women who worked there were tortured and interrogated for weeks, and eventually Róza was betrayed, along with Regina, Ala, and Estusia. Although these four women were tortured and interrogated even further over the next few months, they refused to give up any information and only named names of Sonderkommandos who had already been killed. During this time, Noah Zabladowicz, one of the underground leaders in the camp, managed to steal a visit to Róza, who urged him and the other members of the underground to keep on with their resistance work. Her final message, which was smuggled out of her cell, was a note saying "Hazak v'amatz," Hebrew for "Be strong and brave." Róza and the other three women were publicly hanged in the women's camp on 5 January 1945, two weeks before the camp was evacuated. Their last words, according to survivors, were said to be either "Be strong!" or "Revenge!" In 1991 a memorial at Yad Vashem was dedicated to Róza, Regina, Estusia, and Ala, recognising their act of heroism.
