Arno Lustiger, who died in Frankfurt on 15 May at the age of 88, was a Holocaust survivor and scholar who will be remembered for his research on Jewish resistance to the Nazis and on Gentiles who helped save Jews from the Holocaust.
Born in Bedzin in Upper Silesia, Poland, on 7 May 1924, Lustiger survived several Nazi concentration camps and a death march in the final days of the war from an Auschwitz sub-camp to another camp, before he escaped and was rescued by American troops.
After the war he moved to Frankfurt and was a co-founder of its Jewish community. He built up a successful women's fashion company while writing articles about the German-Jewish history, the Spanish Civil War, the Jewish resistance and the persecution of Jews by Stalin.
From 2004-06 he was visiting professor at the Fritz-Bauer Institute in Frankfurt. The German Green party leader, Claudia Roth, said the country had lost "a great fighter for humanity and democracy".
