Looking forward to my first full day @ehess.fr @campuscondorcet.bsky.social !

Thrilled and profoundly grateful to have joined the faculty @ehess.fr @crh.ehess.fr this week. I can't wait to meet all my new colleagues and students! crh.ehess.fr/index.php?10...

Cold War-era nuclear safety notice, as they still hang in most Swiss apartment buildings. (I still remember bunkers packed to the brim with emergency supplies in most Swiss residential buildings well through the '90s)

What can rumors tell us about the history of the Holocaust? Read my new piece @histknowledge.bsky.social to find out! #INFOCOM historyofknowledge.hypotheses.org/26203

Alles Gute in Paris, liebe @carolinemezger.bsky.social und à bientôt!

This month marks the end of almost 9 years at the @leibniz-ifz.bsky.social. Thank you to everyone who made my time there so special! I will fondly remember working at the Center for Holocaust Studies, leading the INFOCOM Project, and the many fruitful exchanges with colleagues. Auf Wiedersehen!

So proud of my former PhD student Felix Berge, whose book on informal communication in Nazi Germany is about to come out! www.beck-shop.de/berge-hoeren...

All those affected, supporters & interested parties are cordially invited to contact the network. PDs are especially encouraged to join the network. 7/9

I distinctly remember, over a decade ago, how a Russian friend ghasped in utter disbelief that I was watching something like Colbert, and that it was being broadcast on US public TV. That, too, will soon be gone. variety.com/2025/tv/news...

Word in from Andrea Peto that Budapest Pride drew 360k people. Photo to prove it! #BudapestPride #takethatOrban

It's official - my courses for next year @ehess.fr are now online! enseignements.ehess.fr/2025-2026/in...

Bye, bye, Princeton! Thank you to all the wonderful friends and colleagues who helped make this such an unforgetable semester!

I'd rather not ... (US roadside restaurant)

Little trip down memory lane

It's always fun finding your book out in the wild! Here - Princeton University Library

Spent some productive days researching in the collections of YIVO and the Leo Baeck Institute. Thank you to the Davis Center @princeton for funding the trip!

Greatly looking forward to presenting my research at the Davis Center Seminar next week — and discussing it with Jochen Hellbeck and the larger Princeton community, no less! history.princeton.edu/news-events/...

Now that things are becoming more official, I am delighted to announce that I have been elected as Maître de conférences (associate professor) at the EHESS. Thank you to everyone who supported me on the long road to tenure 🙏 I cannot wait to join the brilliant colleagues in Paris! @ehess.fr

Princeton town, showing up right now 🔥

Bravo 👏 👏 👏 www.npr.org/2025/04/01/n...

Another historic document has arrived in my e-mail inbox.

One of the things we can learn from history, I suppose, is that it IS possible to act ethically in deeply unethical times. How each and every one of us decides to do so will help shape the momentous upheavals of the coming years.

One of the more haunting testimonies of our time. time.com/7269604/el-s...

For those interested in last month's roundtable @Princeton on the 2025 German elections, a recording is now online:

Feeling profoundly grateful this weekend 🙏 More details to follow

Some stunning examples of (self-) censorship. Besides the devastating human consequences, I'm not sure how any serious research in the social sciences can be done under such directives.

The purging of American history has begun. National Museum of American History (Washington, DC), March 2025

Even the speech lengths have turned totalitarian.

Grateful to be back at the USHMM for some research this week

When even reading a newspaper becomes a form of doomscrolling...

Missing these kinds of headlines in the US press today: "In the UN General Assembly, the USA, Israel and Hungary, along with Russia and North Korea, vote against a resolution on the Ukraine war" (Süddeutsche Zeitung)

A very informative piece on the recent German elections, the AfD, and its relation to the MAGA movement

What are the repercussions of today's elections in Germany? How are we to understand the earth-shattering success of the AfD, 80 years after the perpetration of the Holocaust? Please join some colleagues and me at this roundtable @Princeton next Tuesday. All are welcome

This is a must-read article on Germany’s AfD party and its connections to Elon Musk and JD Vance. Very timely for Germany’s election tomorrow… time.com/7260499/alic...

It's probably a sign of the times that it's become virtually impossible to locate an available library copy of Arendt's "The Origins of Totalitarianism"

Our colleagues at the Leibniz Institute for the History and Culture of Eastern Europe (GWZO) have launched an impressive online exhibition on the destruction of Ukraine's cultural heritage, just in time for the Russian invasion's 3rd anniversary. ukrainian-destroyed-heritage.leibniz-gwzo.de

Trump's selling out of Ukraine is a betrayal of Ukraine, of Europe, and of the very principles that were supposed to form the foundation of the USA. Shame on the Trump regime and its countless enablers! May history (and eventually, the law) forever condemn you.

Really impressed by how much thought goes into the craft of writing over here ✒️

ICYMI: I published a new article last night about JD Vance and the Christianization of Holocaust memorial sites. religiondispatches.org/jd-vance-is-...

My fellow German historians' nightmare predictions on the consequences of Trump's election are coming true faster than we ever dared imagine. Stop this insanity now!! What Trump, Vance, Musk, the AfD, etc. propagate cannot be normalized!

Ended a long day writing about the Holocaust by posting my son's first love letter in the mail. Thank goodness for my children and the many joys they bring

Really, Google?

With all that is going on, we also have the upcoming German elections to think about. On February 25, I will be speaking at a roundtable organized by Princeton's Program in Contemporary European Politics and Society about the incoming election results — open to the public, all are welcome.

Happening soon, in honor of International Holocaust Remembrance Day: "Teenagers Ruth Cohen, Steven Fenves, and Irene Weiss were deported in crowded freight cars to Auschwitz-Birkenau...we invite you to hear Ruth, Steven, and Irene recount their harrowing experiences" www.ushmm.org/online-calen...

Can't believe we've reached the point of needing to share this, but here goes:

First they came for the Communists And I did not speak out Because I was not a Communist ... Then they came for the Jews And I did not speak out Because I was not a Jew Then they came for me And there was no one left To speak out for me - M. Niemöller (hmd.org.uk/resource/fir...)
