Since 2000, Rosenfeld has taught in the department of history at
Fairfield University, where he offers courses on modern European History, German History, Holocaust History, Jewish History, Memory Studies, and Counterfactual History. He has written widely on how the memory of the Third Reich and Second World War has taken shape in Western culture—especially in architecture, monuments, literature, film, television, and historiography. In this work, he has emphasized how the memory of the Nazi era has become increasingly "normalized." Rosenfeld's 2015 book,
Hi Hitler! How the Nazi Past is Being Normalized in Contemporary Culture (Cambridge University Press, 2015), won the German Studies Association's 2017 Sybil Halpern Milton Memorial Book Prize for the best book dealing with Nazi Germany and the Holocaust. His 2011 book,
Building After Auschwitz: Jewish Architecture and the Memory of the Holocaust, which explores the origins of "new Jewish architecture," was a finalist for the National Jewish Book Award in the category of visual arts. Rosenfeld has also been a leading scholar in the field of counterfactual history. His key works include
The World Hitler Never Made: Alternate History and the Memory of Nazism (2005),
What Ifs of Jewish History: From Abraham to Zionism (2016), and "The Ways We Wonder 'What If?": Towards a Typology of Historical Counterfactuals (2016). In 2013, he created a blog, The Counterfactual History Review, which provides regular commentary on the use of counterfactuals in Western intellectual and cultural life. His new, two-volume book
Predicting the Past: Counterfactual History from Antiquity to the Present will appear in 2026. Rosenfeld's current research focuses on the history and memory of fascism in the United States. His essays on the topic include "An American Führer? Nazi Analogies and the Struggle to Explain Donald Trump" (2019), "Donald Trump's Situational Fascism" (2021), "Beyond Fascism: Trumpism after Trump (2021), and the new volume, co-edited with Janet Ward,
Fascism in America: Past and Present. Rosenfeld has published dozens of essays and opinion pieces in such publications as
The Washington Post, The Atlantic, The New Republic, The Forward,
The Jewish Review of Books,
The San Francisco Chronicle,
The Hartford Courant,
The History News Network,
History Today, and
The Conversation. Rosenfeld has been interviewed by, and had his work cited in,
The New York Times,
The Wall Street Journal, and
The New Yorker, as well as programs on PBS and National Public Radio. On September 1, 2022, Rosenfeld began his tenure as President of the Center for Jewish History in New York City. He has since worked to bolster the Center's reputation as the world's largest Jewish archive by expanding its fellowship program and public programming. In the fall of 2023, he took over the directorship of the CJH fellowship program, which has since been officially renamed the Institute for Advanced Research. In 2024, the Institute welcomed a cohort of ten fellows, ranging from senior scholars to PhD candidates. In April 2023, Rosenfeld helped launch the Jewish Public History Forum, which features major symposia on historical topics of contemporary relevance, including interwar Jewish response to Fascism, the American Jewish debate on Zionism, the role played by American Jews in immigration, and the uncertain place of Jews at American universities. He also co-curated the recent 2024 exhibition, "Between Antisemitism and Activism: The Jewish University Experience in Historical Perspective." == Bibliography ==
