Nathan Mośkiewicz, the last Jew in Koźmiń Wielkopolski, is the focus of a project organized by the Krotochwile Association, which has been restoring the memory of local Jewish communities for many years. After the war, Nathan and his son Hugo returned to their house. Years later Hugo emigrated, but Nathan remained in his hometown until his death in 1969. He was the only worshipper at the synagogue, which was dismantled only after his death. In accordance with his wishes, his Polish neighbors buried him in the Jewish cemetery, alongside his parents. The stories of older residents who still remember their Jewish neighbor will also be collected.
