IZR

Izrael Kalman Poznański was a Polish-Jewish businessman, textile magnate and philanthropist in Łódź, Congress Poland, and the husband of Eleonora Hertz Poznańska. The mausoleum of Izrael and his wife, Eleonora Hertz, on the New Jewish Cemetery has been described as "probably the largest Jewish grave monument in the world". The mausoleum and mosaic covering the inside of the dome were restored in 1993.
