Henryk Ross

If you've never heard of him, he was photographer who documented life in the Polish ghetto of Lodz between 1940 and 1945. He was appointed the Jewish Council's official photographer for the Department of Statistics.

In 1987, Ross wrote:

"Having an official camera, I was secretly able to photograph the life of the Jews in the ghetto. Just before the closure of the ghetto in 1944 I buried my negatives in the ground in order that there should be some record of our tragedy, namely the total elimination of the Jews from Lodz by the Nazi executioners. I was anticipating the total destruction of Polish Jewry. I wanted to leave a historical record of our martyrdom."

Some of the photographs Ross later unearthed were used as evidence at Adolf Eichmann’s trial in 1961.
