Bernhard Lichtenberg was a German Catholic priest and theologian who lived from 1875 to 1943. Serving as a provost at St. Hedwig's Cathedral in Berlin, he became a prominent figure of moral resistance against the Nazi regime. He used his position to publicly denounce the persecution of Jewish citizens and the state's forced euthanasia programs. For his courageous efforts to assist those targeted by the Third Reich, he was later recognized as a martyr and honored by both the Catholic Church and Yad Vashem.
