In the spring of 1940, the German forces occupying Poland drove the Jews of Lodz into the Holocaust's second-largest and most hermetically-sealed ghetto. It functioned both as a sweatshop serving the German war effort, and a prison for Jews en route to the death camps of Chelmno and Auschwitz. Self-governed by its Council of Elders - with its own police force, currency and postage stamps - its leader was the notorious Chaim Rumkowski. He complied with German orders, believing that the value of Lodz's labour might secure survival for the majority. History proved him decisively wrong: 95% of the ghetto's inmates perished. Those who survived starvation rations, disease and prior deportations were removed to the gas chambers of Auschwitz when the ghetto was liquidated in 1944.

Henryk Ross was a photographer employed by the ghetto's Department of Statistics who kept a clandestine diary of ghetto life in powerful and often brilliant images. When the ghetto's liquidation began, he buried them. A survivor, he dug them up after the war, releasing many that were to become icons of the Holocaust's atrocities. But he released only a minority of the pictures during his lifetime. After Ross's death in 1991, his archive - the most extensive collection of ghetto photographs by any single photographer - was acquired by the Archive of Modern Conflict in London.

But other 'private' photographs reveal 'life in the ghetto, with happiness sometimes', as Ross states in his catalogue, showing aspects of a 'privileged' life. Published here for the first time, they add an unexpected, complex and poignant dimension to the photographic record of the ghetto, and demand a reassessment of how we understand its social order. Together with the 'public' photographs, and
