Werner Rudolf Breslauer (4 July 1903 – 28 February 1945) was a German Jewish photographer who documented Nazi atrocities. Breslauer was born in Leipzig, where he was trained as a photographer and as a printer. In 1938, as the Nazis began the extermination of Jews, he fled to the Netherlands, where he lived and worked in Leiden, Alphen, and Utrecht. In 1942, Breslauer, his wife Bella Weissmann, sons Mischa and Stefan and daughter Ursula were imprisoned and deported to Westerbork transit camp. Camp commander Albert Konrad Gemmeker ordered Breslauer to make photographs and films of life in Westerbork. Breslauer and his family were transported to Auschwitz in the autumn of 1944. His wife and two sons were immediately killed, Rudolf Breslauer died a few months later. Their daughter Ursula survived the war.
