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.

University of Michigan will have a leader who defended pro-Palestinian protesters in court
A civil rights attorney who defended pro-Palestinian protesters in court and made social media posts viewed as pro-Hezbollah and antisemitic, has won his bid for the University of Michigan Board of Regents.
Michigan is one of a few states in which voters play a direct role in choosing university overseers. As a regent, Amir Makled (D) will help oversee expenditures at the university where his clients, the student protesters, were arrested. The position is unpaid and carries an eight-year term. Democrat Paul Brown won the other seat up for election, maintaining the board’s 6-2 Democratic majority.
Makled beat out Republican challenger Lena Epstein, who is Jewish and previously identified as a “Jewish Messianic believer of Christ,” but recanted the statement and later said she was “100% Jewish.” Mainstream Judaism does not accept Messianic Jews because they believe in the divinity of Christ and try to convert Jews to Jesus.
Epstein told the Forward in an April interview that the Democrats had handed her an opportunity to win the seat by endorsing Makled, who was facing intense scrutiny. In one of his controversial posts, Makled called Hezbollah leader Hassan Nasrallah a “martyr” after he was killed by Israeli strikes in 2024. He lost an endorsement from Service Employees International Union for the posts and later deleted them.
In the regents race, voters picked up to two of six candidates, with the top two winning. Makled received 25.6% of the vote while Brown received 27.2%. Epstein received 22.2% while her fellow Republican Michael Schostak received 22.6%.
Makled’s election comes as part of a wave of Democratic Party wins, including in Michigan, which elected as Senator Abdul El-Sayed (D), who also faced severe backlash for statements related to Israel and Gaza and for appearing alongside streamer Hasan Piker, who has been accused of antisemitic rhetoric.
Israel played a major role in the rhetoric surrounding Michigan’s midterms. But voters, including 60% of Jewish voters that voted for El-Sayed according to early exit polls, favored sharp critics of the Jewish state to candidates in support of it.

This grandson of Holocaust survivors is headed to Congress. The ADL has concerns about his antisemitism record.
The election of Daniel Biss, a Jewish critic of Israel, to an Illinois congressional seat Tuesday has sparked a public feud between the Anti-Defamation League and the liberal Zionist group J Street over whether the ADL remains a credible voice in the fight against antisemitism.
After Biss, the former Jewish mayor of Evanston, Ill., won his seat Tuesday night, the ADL Midwest took to social media to express “serious concerns” about Biss’ “approach to antisemitism.”
J Street, which had endorsed Biss, hit back, noting that Biss is the grandson of Holocaust survivors and calling the ADL’s statement “a shanda,” the Yiddish word for disgrace.
“It is hard to read this statement without wondering how far the ADL has drifted from the organization it once was – a gold standard in our community for standing up against bigotry, hatred and discrimination,” J street wrote on X.
Biss, who speaks Hebrew and spent childhood summers in Israel, was elected with 75% of the vote in a district where 11% of the electorate is Jewish.
“It saddens me to watch the ADL, once a preeminent civil rights organization, devolve into an entity that traffics in fear, intimidation and extremism,” Biss wrote in a statement to the Forward. “This kind of rhetoric does nothing to keep the Jewish people safe—in fact, it undermines that very cause.”
The ADL has long faced scrutiny from critics who view the watchdog group as labeling too broad a swath of Israel criticism as antisemitic, while less forcefully condemning antisemitism when it comes from the political right.
“Our statement speaks for itself,” an ADL spokesperson wrote in an email to the Forward.
In its statement, the ADL pointed to a specific set of concerns involving Biss’ record as mayor of Evanston, Illinois, the college town home to Northwestern University.
Biss did not provide Evanston police support that Northwestern requested after reported “antisemitic conduct” at the Gaza war encampment on campus in April 2024, the ADL said, “raising serious questions about whether the safety, dignity, and equal access of Jewish students were treated with the urgency they required.”
Biss has defended his decision not to dispatch police to the encampment, writing in response to a congressional inquiry that forcibly clearing the protest would have gone against police department advice and suppressed “constitutionally protected speech.”
The ADL also said that Biss “dismissed scrutiny of his response as a politically motivated attack fueled by AIPAC, rather than substantively addressing the concerns raised by Jewish students and community members.”
Biss made opposition to AIPAC a central theme of his primary campaign for Congress after the hardline pro-Israel lobbying group spent millions opposing him and supporting another candidate, state Sen. Laura Fine.
In an interview with the Forward in March, Biss said it was “absurd” that AIPAC opposes imposing any conditions on U.S. military aid to Israel. “And then try to enforce it with millions of dollars of dark money, is certainly bad for democracy and bad for our politics here in America,” Biss added.
At the same time, Biss faced pressure to his left on Israel in the primary, defeating Kat Abughazaleh, a Palestinian-American who has characterized Israel’s conduct in Gaza as a genocide. Biss, who has described himself as a progressive Zionist, declined to use the word genocide, despite repeated calls from Abughazaleh to do so.
In a March op-ed in The Nation, Biss wrote that he believed he was one of AIPAC’s top targets partly because “I’m the grandson of Holocaust survivors. My mother is Israeli. My extended family lives in Israel. AIPAC knew that they couldn’t dismiss me as anti-Israel or antisemitic.”
The ADL also criticized Biss for supporting the repeal of an anti-BDS law, which bars Illinois from investing public pension funds in companies that boycott Israel. That position, the ADL said, “raises additional concerns about his willingness to stand against efforts to isolate and delegitimize the Jewish state.”
In an April Substack post explaining his position, Biss said that he personally opposes the global movement to boycott Israel, but he does not believe the government should “stop people from using their economic agency to advocate for their values.”
Biss will succeed Rep. Jan Schakowsky, a Jewish lawmaker who represented the district for nearly three decades and was also an outspoken critic of AIPAC.

At the Vatican, two elderly men — one Jewish, one Catholic — exchange gifts and mutual admiration
On Wednesday, two senior citizens, Robert Zimmerman, 85, a Jew originally from Minnesota, and Robert Prevost, 71, a Catholic of Chicago, had a brief meeting at the younger man’s office in central Italy.
Sources on the scene report that Zimmerman was in town for business and Prevost, who goes professionally by Leo, had recently cited Zimmerman’s work in the preface to a book about nuclear disarmament.
Both men dressed in uniform, looking a bit Spy Vs. Spy, with Zimmerman in a black hoodie and Prevost in white with a small white skull cap. The confab was brief, a bulletin from Prevost’s workplace reported, consisting of “greetings and a few lighthearted exchanges.”
Prevost gifted Zimmerman with prayer beads, and Zimmerman presented Prevost with a copy of his memoir, published under his pen name, Bob Dylan.
While Zimmerman was raised in a Jewish home, he had, for a time in the late 1970s to early 1980s, converted to born-again Christianity, confounding many.
