A German town built a granary atop its Jewish cemetery. Now the bones are yielding insights about Ashkenazi DNA.
BERLIN (JTA) – The city of Erfurt in central Germany is home to an impeccably restored medieval synagogue made possible because local Jews had been expelled long before the Nazis began their campaign to destroy Jewish sites.
Now, Erfurt’s long-hidden Jewish past is again offering new insights — this time about the genetic history of Ashkenazi Jews.
Human remains from a medieval Jewish cemetery in Erfurt have allowed what researchers say is the largest ancient Jewish DNA study to date. Conducted without disinterring any remains, in keeping with Jewish law, the study published Wednesday in the scientific journal Cell found that Erfurt’s medieval Jewish community was more genetically diverse than their modern-day cousins, and carried many of the same Jewish genetic diseases — such as Tay Sachs and cystic fibrosis — that affect Ashkenazi Jews today.
“There have been many previous DNA studies, but not of Jews,” said geneticist Shai Carmi, a professor at the Hebrew University of Jerusalem, whose search for study material led him to an archaeological dig at the Jewish cemetery in Erfurt. He and his collaborators were able to analyze DNA of 33 individuals who died between 1270 and 1400, using teeth they found there.
The study follows a similar analysis revealed in August by researchers in England, who studied the DNA from skeletons found at the bottom of a medieval well and concluded that the remains were likely of victims of an antisemitic massacre in 1190. Analysis of six individuals prior to their identification as Jewish revealed that Ashkenazi Jews developed a unique genetic variation centuries earlier than realized.
The Erfurt analysis also includes samples from before the epidemic of Black Death that was until recently understood to have created the genetic “bottleneck” that created the genetic markers common among Ashkenazi Jews today.
Erfurt’s Jewish settlement existed from the 11th to 15th century, with a brief gap following a 1349 massacre perpetrated after the Jews were falsely blamed for causing the bubonic plague. Surviving Jews returned there, but after all Jews were expelled once and for all in 1454, the city built a granary on top of the Jewish cemetery.

In 2013, the city approved the repurposing of the unused granary into a parking lot. Because it was an historic site, a rescue excavation was initiated, overseen for the State of Thuringia by German archaeologist Karin Sczech.
Meanwhile, Carmi had been looking for Jewish cemeteries anywhere in the world “where we could analyze remains already excavated,” he told JTA in a telephone interview from Jerusalem. “I consulted historians and eventually reached the archeologist in Erfurt.” Fortunately, he said, “they still hadn’t reburied the remains.”
He approached Sczech, who later became a co-author of the new study. In 2018, with a supportive judgment from Rabbi Ze’ev Litke — an Israeli expert on genetics and Jewish law — and permission from Erfurt’s then-rabbi, Benjamin Kochan, work began to extract and analyze DNA from detached teeth found in the graves. (About 500 Jews live in Erfurt today, most of them having migrated from the former Soviet Union since 1990.)
American geneticist David Reich picked up the teeth and brought them back to the department of human evolutionary biology at Harvard University in Cambridge, Massachusetts, where drilling and DNA extraction took place.
While the skeletons were reburied, the teeth are still stored at the research institutes where they have been analyzed, in case scientists need to retest to verify the result.
The project provides an ethical basis for studies of ancient Jewish DNA, Carmi said. “Of course we couldn’t just go to a cemetery and dig and take out skeletons; this would be prohibited,” he said, referring to Jewish law prohibiting the removal of bones from where someone was buried.
But Litke opined that the study could be done, because the bones already had been disturbed for an unrelated reason. “He recommended using teeth, as the analysis does almost no damage,” Carmi said.
There are many motivations to study Jewish DNA: One can find lost relatives going back a few generations, and answer questions about Jewish origin of partners intending to marry. But the goal of Carmi’s team was “to fill the gaps in our understanding of Ashkenazi Jewish early history.”
There are several non-destructive ways to obtain DNA from human remains, said Carmi, who also works as a consultant to an Israeli firm that helps clients trace their genetic roots.
“You can take an almost microscopic slice of bone and extract DNA in a solution, or put the entire bone in a solution and extract the DNA without drilling, without disturbing the dead. This opens the way to doing studies even without teeth,” he added.
His team found that the Erfurt community appeared to fit into two genetically distinct groups, descending either from Middle Eastern or European populations. This genetic variability no longer exists, Carmi said.
At the same time, Carmi said, the analysis found remarkable continuity in the local community, as well. “One third of the Erfurt individuals descended from one woman through their maternal lines,” he said, adding that evidence suggested that she lived between 1,000 and 2,000 years ago.
In a press statement, geneticist Reich of Harvard said the work “also provides a template for how a co-analysis of modern and ancient DNA data can shed light on the past. Studies like this hold great promise not only for understanding Jewish history, but also that of any population.”
The research team, with more than 30 scientists, included Hebrew University’s Shamam Waldman, a doctoral student in Carmi’s group, who performed most of the data analysis.

Vanderbilt launches inquiry into instructor after math question about Israeli occupation draws criticism
(JTA) — Vanderbilt University has launched an inquiry into a mathematics lecturer whose classroom exercise about Palestinian territory drew criticism from the activist group StopAntisemitism.
Tekin Karadağ, a senior lecturer at the university’s department of mathematics, drew the ire of the antisemitism watchdog after it obtained a slide from one of his lectures that used a pro-Palestinian protest slogan and suggested that Israel was shrinking the Palestinian territory.
“Assume Palestine as a state with a rectangular land shape. There is the Mediterranean Sea on the west and the Jordan River on the east,” read the slide. “From the river to the sea, Palestine (…) was approximately 100 km. in 1946. The land decreases by 250 sq. km per year, due to the occupation by Israel. How fast is the width of the land decreasing now?”
Karadǎg, a Turkish national who received his PhD from Texas A&M University in 2021, included the question under “examples related to the popular issues” in a survey of calculus class, according to StopAntisemitism, which wrote in a post on X that Karadǎg was “bringing his anti-Israel, antisemitic bias into his classroom.”
In a statement shared with the Jewish Telegraphic Agency, Vanderbilt said that the content had been removed and that an inquiry had been launched into Karadağ.
“The university has received reports alleging a member of the faculty engaged in unprofessional conduct related to content shared during course instruction,” the school said. “The content in question has been removed, and a formal inquiry has been initiated consistent with relevant university policy.”
In recent years, rhetoric about the Israeli-Palestinian conflict on college campuses has grown increasingly fraught, with professors’ commentary on the region sparking heavy scrutiny and, at times, disciplinary measures when their universities have determined that they exceeded the bounds of academic freedom. A recent report by Columbia University’s antisemitism task force found that students frequently experienced pro-Palestinian advocacy in classes entirely unrelated to the Middle East — such as dance or math classes.
The inquiry was not the first time that Vanderbilt took swift action against the expression of pro-Palestinian sentiments on its campus.
In March 2024, the university, which has roughly 1,100 Jewish undergraduate students, was among the first universities to expel students who participated in pro-Palestinian demonstrations. This year, the school’s antisemitism “grade” from the Anti-Defamation League was bumped up from a “C” to an “A.”

Hugh Laurie rejects ‘Zionist’ label after his tribute to Israeli ‘Tehran’ producer sparks social media firestorm
(JTA) — British actor Hugh Laurie pushed back against being labeled as a “Zionist” after facing a wave of online criticism for posting a tribute to the Israeli producer of the hit television show “Tehran.”
“Dana Eden, who co-created and produced ‘Tehran’, died on Sunday, seemingly by her own hand,” Laurie, who played a nuclear inspector in the show’s third season, tweeted last week. “It’s a terrible thing. She was brilliant, and funny, and an exceptional leader. Love and condolences to all who knew her.”
The seemingly innocuous post eulogizing Eden, 52, who was found dead while filming the latest season of the hit Apple TV+ series in Athens last week, quickly drew a volley of backlash on social media.
“She was part of the occupation force’s propaganda arm,” wrote one user in response to Laurie’s post. “What a shame, didn’t expect you to be a closet Zionist.” Another wrote that Eden “creates propaganda for Israel so that they can kill kids more effectively. People should have no sympathy for her.”
The award-winning series, which follows a young Israeli Mossad agent in Iran, was produced by the Israeli public broadcaster Kan and purchased by Apple TV+ in 2020 for roughly $20 million. Eden’s death, for which no cause has been announced, occurred during production of the show’s fourth season, which had already stalled following Oct. 7.
Laurie is not the first actor to spurn the “Zionist” label, as entertainers in recent years have increasingly faced pressure to declare their views on Israel. In December, Jewish actress Odessa A’zion pushed back on claims she was a Zionist after an image of her wearing an IDF shirt as a teenager circulated online.
On Friday, Laurie, who previously starred in the Emmy Award-winning medical drama “House,” shot back at the criticism.
“Nothing I have ever said or done could lead a sane person to believe that I am a Zionist,” wrote Laurie in a post on X. “However. If someone exults in the death of a friend of mine, yes I will block them. If you wouldn’t do the same in my position, you can f—ck off too.”
Laurie’s subsequent post also drew outcry, but this time from pro-Israel influencers who lamented the actor’s disavowal of the Zionist label, calling him “weak” and a “pathetic weasel” in the replies.
Freelance journalist Angela Epstein replied to Laurie’s post, writing, “Not Hugh Laurie as well. I thought he was one of the decent ones….”
“God almighty, why does no one understand English any more?” wrote Laurie in response to Epstein’s critique. “I have not spoken or written a word that would indicate pro or anti Zionism. That’s what those words mean. Blimey.”

German anti-Zionist group’s plan to protest at Buchenwald memorial over kaffiyeh ban sparks outrage
(JTA) — An anti-Zionist group in Germany has drawn condemnation after it announced plans for a protest against the Buchenwald concentration camp memorial in response to a ban on pro-Palestinian symbols at the site.
The group Kufiyas in Buchenwald claims that the memorial has become a place of “historical revisionism and genocide denial.” It announced a demonstration for April 11, the anniversary of the liberation of the Nazi concentration camp.
“Instead of honoring the persecuted and resolutely opposing every genocide, the memorial spreads Israeli propaganda and provides the ideological ammunition for the ongoing genocide in Palestine,” the group says on its website.
Buchenwald, one of the first concentration camps built by the Nazis and one of the largest in the country, was the site of the murder of roughly 56,000 male prisoners, including 11,000 Jews, from 1937 to 1945.
Last year, a German court ruled that the concentration camp had a right to refuse entry to visitors who wear a keffiyeh, a traditional Palestinian headscarf that has been adopted by pro-Palestinian protesters. The ruling stemmed from a lawsuit by a woman who attempted to wear the scarf to an event commemorating the concentration camp’s liberation.
The woman, who was only identified by her first name, Anna, posted a testimony about her actions on the Kufiyas in Buchenwald Instagram page in which she said she was inspired by the resistance of Buchenwald prisoners.
“Our fundamental principle is this: criticism of the Israeli government’s policies, settlement policy, or actions in the Gaza Strip is legitimate,” said the Buchenwald Foundation’s director Jens-Christian Wagner in a statement outlining the memorial’s protocols. “However, it becomes antisemitic when used to relativize the Holocaust and discredit its victims as perpetrators. We will not tolerate this at the Buchenwald Memorial.”
The campaign against the memorial has been signed onto by a host of pro-Palestinian groups, including the International Jewish Anti-Zionist Network and the German group Jewish Voice for a Just Peace in the Middle East, which has defended the protest on X as evidence of what “commemorating past German crimes has to do with rejecting current ones.”
In a post on Instagram announcing the protest earlier this month, the Kufiyas in Buchenwald group wrote that it would hold a “public protest” in Weimar, the German city located nearby the concentration camp. The group also said it planned to host lectures and a “tour that vividly illustrates the events in the former concentration camp.”
It was unclear whether the protest is intended to take place outside the memorial itself. Kufiyas in Buchenwald did not immediately respond to an inquiry from the Jewish Telegraphic Agency about the location of the protest.
The protest quickly drew condemnation from German leaders, including the country’s antisemitism czar Felix Klein, who told the Swiss outlet Neue Zürcher Zeitung that the protest marked a “new low point in the unfortunately all-too-common reversal of perpetrator and victim roles.”
Michael Panse, the commissioner for combatting antisemitism for the German state Thuringia, where Weimar is located, told the outlet that the protest was “tasteless and historically ignorant.”
The protests also drew condemnation from the European Jewish Congress, which wrote in a post on X that the demonstration represents a “deeply troubling instrumentalization of Holocaust remembrance.”
“Holocaust memorial sites are places of solemn reflection and respect for the victims of National Socialism,” the post continued. “They must never be exploited to promote agendas that deny Israel’s legitimacy or glorify those who perpetrate violence against Jews.”
