Julius Wolff

Julius Wolff was a Dutch-Jewish mathematician, known for the Denjoy–Wolff theorem and for his boundary version of the Schwarz lemma. With his family he was arrested in Utrecht by the Nazi occupation forces of the Netherlands on 8 March 1943 and transported to the Bergen-Belsen concentration camp on 13 September 1944, where he died of epidemic typhus on 8 February 1945, shortly before the camp was liberated.
