Photographs that show the horrors and complexities of life in the Lodz Ghetto in 1940 — images that the Nazis banned and were buried for safekeeping and later retrieved by the photographer — will be exhibited at the Museum of Jewish Heritage — A Living Memorial to the Holocaust in Manhattan. Organized by the Art Gallery of Ontario, the exhibit, “Memory Unearthed: The Lodz Ghetto Photographs of Henryk Ross,” will be on display at the museum from February 25 to June 24.
