Józef and Wiktoria Ulm lived in Markowa, a village about 300 km away from Warsaw. Joseph was a farmer, also interested in photography, gardening, silkworm breeding, machinery construction. He was also active in the youth and cooperative movements. Wiktoria took care of home and children: Staś, Basia, Władzio, Franuś, Antoś, Marysia.
When World War II broke out it was clear that first the Nazis planned to exterminate the entire Jewish community. Most of them perished in concentration camps in 1942. Poles attitude towards Jews varied. However, with the help of the Underground Polish State, Catholic priests, religious orders and ordinary citizens tens of thousands of Jews were rescued.
In Markowa large part of the local Jewish community was murdered on the spot. Some escaped and hid in peasants’ homes. 25 Jews were hiding in 6 huts. Two families - Szalls and Goldmans - were hidden by the Ulms. It was great heroism. In occupied Poland, in contrast to Western Europe, helping Jews was punishable with death.
Punitive expedition of the German police appeared in Markowa on 24 March 1944. All household members, including the hidden Jews were shot.
In 1995 Józef and Wiktoria were included to the Righteous Among the Nations. In 2003 the Catholic Church began the beatification process of the Ulm family. In 2004 a monument was unveiled. Also a museum devoted to Poles saving Jews is under construction in Markowa.
