History
The Nissenbaum Foundation was established in 1983 by Sigmund Nissenbaum, a Polish-born Holocaust survivor. According to its official website, it was the first foundation created in Poland after the Second World War, and its initial activities and financial outlays began that same year. From the outset, the foundation focused on rescuing the traces of Jewish culture on Polish soil, a mission that reflected the founder's personal history and the broader need to preserve a heritage largely destroyed during the Holocaust. Under Sigmund Nissenbaum's leadership, the foundation carried out numerous projects throughout Poland. Work included fencing and tidying Jewish cemeteries, restoration of ohels and synagogues, and the placement of memorial plaques at sites of Jewish martyrdom. A particularly significant undertaking was the foundation's active participation in renovation work at the New Jewish Cemetery in Łódź, the second-largest Jewish cemetery in Europe. Over the years, the foundation's projects have reached dozens of localities across the country, from large cities such as Warsaw, Kraków, Łódź and Lublin to smaller towns and villages. Sigmund Nissenbaum served as president of the foundation until his death in 2001. He was succeeded by his wife, Sonja Nissenbaum, who led the organization from 2001 until her death in 2018. During her tenure, the foundation continued its restoration and commemoration work and became one of the 21 Distinguished Donors of the POLIN Museum of the History of Polish Jews in Warsaw, a major cultural institution opened in the Polish capital. In January 2019, Gideon Nissenbaum became president of the foundation, continuing the family's leadership into a new generation. The foundation remains active, headquartered in Warsaw at ul. Edwarda Gibalskiego 21. Its official website presents an interactive map of projects across Poland, listing dozens of cities and towns where it has worked, including Mielnik, Lubliniec, Mszczonów, Radzymin, Tykocin, Kazimierz Dolny, Wola, Wodzisław-Świątniki, Lublin, Kolbuszowa, Tarnogóra, Gliwice, Kock, Okuniew, Tarnów, Głowaczów, Puławy, Chełm, Legnica, Gorlice, Mława, Słomniki, Chorzele, Gołdap, Słubice, Sędziszów Małopolski, Przysucha, Krosno, Cieszanów, Treblinka, Czarny Dunajec, Krościenko nad Dunajcem, Wiślica, Busko-Zdrój, Zamość, Leżajsk, Szydłów, Grójec, Szydłowiec, Kielce, Łódź, Bielsko-Biała, Bobowa, Kalisz, Andrychów, Czechowice-Dziedzice, Karczew, Kraśnik, Płońsk, Radomsko, Rzeszów, Sanok, Seroczyn, Sochaczew, Strzyżów, Wolbrom, Zabrze, Gąbin, Muszyna, Buk, Dębica, Sopot, Krynki, Różan, Góra Kalwaria, Częstochowa, Sławatycze, Puszcza Niepołomicka, Warsaw, Kraków and Lelów.
