Monday marks the 75th anniversary of the liberation of the Auschwitz death camp in German-occupied Poland by Red Army troops. Martin Schoeller, a photographer, collaborated with Kai Diekmann of the German Friends of Yad Vashem, the Holocaust Remembrance Center in Jerusalem, to create 75 portraits of Holocaust survivors for the anniversary.Born in Germany, Mr. Schoeller recalls that his education in the 1980s was dominated by the history of the Third Reich. Those in his generation were raised with a monumental sense of guilt and disbelief that their grandparents could commit such abhorrent crimes. With anti-Semitism, Holocaust distortion and denial on the rise in many countries, he felt that it was his professional and personal responsibility to not only reflect on and learn from the Holocaust, but to help memorialize it.
