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.

Remains of final hostage Ran Gvili on way back to Israel after being located in Gaza
(JTA) — The remains of the final Israeli hostage in Gaza, Ran Gvili, have been retrieved and are on their way back to Israel for burial.
The announcement by the Israeli military marks a significant milestone for the Israeli public, which transformed into a communal vigil for the hostages taken when Hamas attacked on Oct. 7, 2023. It also removes an obstacle to the second phase of the U.S.-brokered ceasefire between Israel and Hamas.
Gvili, a 24-year-old police officer, was killed defending Kibbutz Alumim on Oct. 7. His remains were recovered from a cemetery in Gaza City during a major military operation, the IDF said. Hundreds of bodies were reportedly exhumed during the search and are being reburied.
“The return of Ran z”l for burial is a painful moment of closing the circle—with the return of the last hostage from the Gaza Strip territory to the soil of Israel,” said Israeli Minister of Defense Israel Katz in a post on X. “This is a moment that underscores the State of Israel’s commitment to its fighters and citizens: to bring every single one home—as we promised the families and the public in Israel. This is mutual responsibility.”
Four of the hostages released under the ceasefire deal had been held since before Oct. 7, meaning that Gvili’s return marks the first time since 2014 that there will be no Israeli hostages in Gaza.
Earlier this month, the Trump administration announced that the second phase of the Gaza ceasefire had commenced despite opposition from Gvili’s family who said his body should be returned first.
Since then, the Trump administration has announced the formation of an international “Board of Peace” to oversee the ceasefire and presented plans for the reconstruction of Gaza. On Monday, Israeli Prime Minister Benjamin Netanyahu’s office announced that it would reopen the border between the Gaza Strip and Egypt after the search for Gvili’s remains was completed.
Gvili’s mother, Talik, said the news of his return is “a relief, after these two and a half years, even though we hoped for a different ending,” according to the Times of Israel.
The discovery of Gvili’s remains was also celebrated by Israeli soldiers at the cemetery where he was found. Video of the soldiers posted on X showed many embracing and singing “Ani Ma’amin,” a Hebrew song meaning “I Believe.”
Some Jews and Jewish institutions removed their hostage necklaces and dismantled their displays in support of the hostages after all of the remaining living hostages were released in October. Others posted social media videos of themselves doing so on Monday following the news of Gvili’s return.
Speaking to the media in the Knesset on Monday, Netanyahu said, “We promised, and I promised, to bring everyone back, and we brought everyone back,” adding, “Rani is a hero of Israel. He went in first, he came out last. He came back.”

Columbia selects Jennifer Mnookin, Jewish U of Wisconsin chancellor, as its next leader
(JTA) — Three different women have taken turns as Columbia University’s president amid ongoing turmoil surrounding the handling of pro-Palestinian protests on the New York City campus. Now, Columbia has invited a fourth — and the first to be Jewish — to try her hand at running the Ivy League school.
Jennifer Mnookin, the chancellor of University of Wisconsin, has been chosen as Columbia’s next president, the co-chairs of the school’s board of trustees announced on Sunday. She will be the school’s first Jewish leader since Oct. 7, 2023, when Hamas attacked Israel, triggering a war in Gaza and a student protest movement in the United States of which Columbia was an epicenter.
Mnookin, a legal scholar, served as dean of the University of California, Los Angeles School of Law before moving to Wisconsin in 2022. At least two other candidates reportedly declined the Columbia position prior to her selection.
She takes the helm at a delicate time for Columbia as it continues to reel from the fallout of the student protests, which has included included penalties from the Trump administration, rapid leadership changes and ongoing fear and anxiety among many Jewish students.
“I am honored and thrilled to join Columbia University at this important moment,” Mnookin said in a statement released by the university. “Columbia is defined by rigorous scholarship, a deep commitment to open inquiry, world-class patient care, and an inseparable and enduring connection to New York City, the greatest city in the world.”
She follows three other women who struggled amid the turmoil. The president in charge on Oct. 7, Nemat Minouche Shafik, cited the “period of turmoil” that followed when she resigned in 2024; she had faced criticism from members of Congress as well as the Columbia community over her handling of the student encampment that formed this year.
Her temporary replacement, Katrina Armstrong, stepped down in March 2025 as the school faced pressure from the Trump administration over antisemitism allegations. Armstong’s successor, the current interim president, Claire Shipman, struck a $221 million deal with Trump to settle the claims; she also apologized soon after taking office for having suggested the removal of a Jewish member of the school’s board of trustees.
Now, Mnookin will be responsible for managing Columbia’s relationship with federal authorities, weighing and implementing the recommendations of its antisemitism task force and healing a divided campus, which has been closed to outsiders now for years.
“The last few years have been undeniably difficult for the Jewish and Israeli communities on campus. While challenges remain, there is a vibrant, joyful, proud Jewish community at Columbia,” Brian Cohen, executive director of Columbia/Barnard Hillel, said in a statement. “I am hopeful that President-elect Mnookin will bring the reputation, experience, and understanding that we need to build on that strong foundation.”
It will be Mnookin’s first time working at a private university. At Wisconsin, first sent law enforcement to shut down a student encampment, then negotiated with protesters after they established a second one. The deal required Students for Justice in Palestine to comply with university rules related to protest in exchange for the right to present their divestment demands to “decision makers,” who did not accede to them.
She also denounced neo-Nazi protesters who marched on the Wisconsin campus in November 2023, calling them “utterly repugnant.” Through it all, she gained a reputation for promoting open inquiry and academic freedom — even as Wisconsin, like dozens of other universities, faced a federal investigation over antisemitism allegations.
“I think universities should be spaces where ideas, and different ideas, embodied by people from different backgrounds, come together, and where it won’t always be comfortable, but where we will learn and do better from that engagement,” she said in a roundtable of college presidents published in The New York Times in November. (The other presidents were also Jewish: Sian Bellock of Dartmouth College and Michael Roth of Wesleyan University, who has emerged as a rare leader in higher education who is willing to spar with the Trump administration.)
Mnookin was raised in a Reform Jewish family in the Bay Area that escalated its Jewish engagement when she asked to celebrate her bat mitzvah, according to her father Robert. A scholar of conflict negotiation, he described the evolution in his 2015 book “The Jewish American Paradox: Embracing Choice in a Changing World,” which he said he wrote in part to explore his own late-onset attachment to Judaism.

Tim Walz invokes Anne Frank in pressing Trump to end ICE operations in Minnesota
(JTA) — Tim Walz, the governor of Minnesota, invoked Anne Frank in exhorting President Donald Trump to call off the ICE operations in the Twin Cities in which a second protester was killed over the weekend.
Speaking at a press conference on Sunday, Walz — whose master’s degree focused on Holocaust education — suggested that the conditions facing children in his state during the Trump administration’s aggressive immigration enforcement raids were of a kind with those facing Frank during the Holocaust.
“We have got children in Minnesota hiding in their houses, afraid to go outside. Many of us grew up reading that story of Anne Frank,” he said. “Somebody is going to write that children’s story about Minnesota.”
The prominent mention of Frank, who died of disease in a Nazi concentration camp after her family’s hiding place was betrayed, adds to a growing discourse about whether ICE’s operations targeting immigrants in Minnesota can be compared to the Nazis’ tactics in rooting out Jews during the Holocaust. Figures such as Stephen King and Bruce Springsteen have likened ICE to the Gestapo.
Until recently, Nazi comparisons were long considered inappropriate by many in the Jewish world who argued that such analogies cheapen the memory of the particular genocide against the Jews. In the last decade, that norm has to some degree fallen away, with voices on both the right and left likening their opponents to Nazis.
On Sunday, some of Walz’s critics denounced his comments and said an immigration crackdown cannot be compared to the deliberate murder of Jews. Retweeting an account called Stop Wokeness, the activist Shabbos Kestenbaum tweeted, “One million Jewish children were killed during the Holocaust. Illegal immigrants are offered thousands of dollars to take a free flight home. Tim Walz is an evil retard.”
In a post on X responding to Walz’s analogy, Stephen Miller, a top aide to Trump, wrote, “The purpose of the rhetoric is to incite attacks on ICE.”
But others said the comparison was apt, with a quotation from Frank’s diary circulating widely online as it did in 2019 in response to ICE raids then. The quotation, those sharing it suggested, offered a close parallel to what has been playing out in Minnesota.
“Terrible things are happening outside,” the passage says. “Poor helpless people are being dragged out of their homes. Families are torn apart; men, women and children are separated. Children come home from school to find that their parents have disappeared. … Everyone is scared.”
Jewish voices, too, have invoked the Holocaust in arguing for intervention in Minnesota, where federal agents on Saturday shot and killed a man, Alex Pretti, who had been protesting their presence.
“What did we learn from the Holocaust? We have to act and we have to resist,” one rabbi who flew into Minnesota to protest told the Religion News Service last week.
Walz, a Democrat who was the vice presidential candidate in 2024, wrote a master’s thesis on Holocaust education, arguing that the Holocaust should be taught “in the greater context of human rights abuses,” rather than as a unique historical anomaly or as part of a larger unit on World War II.
“Schools are teaching about the Jewish Holocaust, but the way it is traditionally being taught is not leading to increased knowledge of the causes of genocide in all parts of the world,” he wrote in his 2001 thesis, completed while he was a high school teacher.
