Bauer, who fled Nazi Europe shortly before World War II and became one of the foremost historians of the Holocaust, combined academic rigor with humanity as he confronted an unfathomable event and sought to discern its meaning for the future. As a young Israeli historian, he did not set out to become an authority on the Holocaust, or the Shoah, another term used to describe the murder of 6 million Jews by the Nazis and their collaborators. Over the next half-century, Dr. Bauer wrote dozens of books that helped form the foundation of modern understanding of the Holocaust and antisemitism. He had lost his extended family in the slaughter, and his work served, in part, to document what had befallen them and so many other victims of Nazi persecution. But he did not regard it as his role simply to “memorialize” the dead, he wrote in his book Rethinking the Holocaust (2001). Instead, he wrote, “I ask questions about what happened and why.” That line of inquiry led him to move beyond existing Holocaust scholarship, which relied in large part on the Nazi bureaucracy’s paper trail and centered on the perpetrators. No true understanding of the Holocaust would ever be reached, Bauer maintained, without studying the victims.
In books including They Chose Life: Jewish Resistance in the Holocaust (1973), Bauer challenged a pernicious notion circulating at the time that Jews went “like sheep to the slaughter.” Citing diaries, correspondence, and oral histories, he showed that the Warsaw ghetto uprising of 1943 - when hundreds of Jewish fighters mounted the best known revolt against the Nazis - was far from the only act of insurrection by Jews in ghettos or elsewhere. He also highlighted on the everyday efforts by Jews to retain the dignity that the Nazis tried to strip away.
Bauer wrote extensively about the American response to the Holocaust, including in the book American Jewry and the Holocaust: The American Jewish Joint Distribution Committee, 1939-1945 (1981), and was among scholars who argued that President Franklin D. Roosevelt was unfairly condemned for what critics regarded as his insufficient efforts to stop the Holocaust as it was in progress. Later, Bauer had the painful experience of observing the emergence of pseudo-historians who sought to deny that the Holocaust had occurred or to suggest that the killing had been more limited than was generally understood.
Bauer taught for years at Hebrew University; served as an academic adviser to Yad Vashem, the Holocaust remembrance center in Jerusalem; and helped found the journal Holocaust and Genocide Studies. He explored topics including the founding of the state of Israel and the nature of modern antisemitism. His final books included The Jews: A Contrary People (2014). Bauer’s honors included the Israel Prize, one of the country’s highest honors, bestowed on him in 1998. He spoke critically of Israeli leaders, particularly Prime Minister Benjamin Netanyahu, whom he accused of using the Holocaust for nationalistic purposes and as a “tool for politics.”
