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.

At the Vatican with Chicago’s mayor, a rabbi gave Pope Leo a White Sox kippah
(JTA) — Lizzi Heydemann didn’t plan what she was going to say to Pope Leo XIV.
But when the Chicago rabbi found herself face-to-face with the new pontiff during a Vatican visit alongside a delegation of Chicago leaders, she thanked him for the way he has spoken about the war in Gaza.
“I said, you know, it’s been a hard time over these past two years to be a rabbi, but I want to thank you for, in the midst of conflict, holding the humanity of everyone involved in the conflict,” Heydemann recounted.
Leo, the first American pope and a native of Chicago’s South Side, repeatedly advocated after his election last year for the release of the Israeli hostages as well as a ceasefire in the war in Gaza, which he has referred to as “vengeance” and “barbarity.” The comments angered some Jewish leaders who have interpreted them as unfairly targeting Israel, but for others including Heydemann, they have offered a template for how to criticize the war.
“You may be anti-war, but I do not hear you denouncing or degrading people,” Heydemann said she told Leo. “Thank you for holding the humanity of Israelis and Palestinians in the same breath and the same thought. It’s not something that is modeled very often.”
She added, “He seemed grateful, and like he knew exactly what I was talking about.”
Heydemann, the founder and leader of Mishkan Chicago, an independent Jewish spiritual community, had been invited by Chicago Mayor Brandon Johnson to join a delegation of civic, business and faith leaders traveling to Rome last week. (Johnson has been a vocal critic of Israel who has drawn criticism himself from some Jewish leaders in Chicago.) She said she was the only rabbi to take part in the trip.
As she waited for the pope to enter a room where the delegation was assembled on Thursday, Heydemann said she began weeping.
“What I reflected on is that he, maybe more than anyone in the world, is a religious leader with the world’s eyes on him,” Heydemann said. “He is beloved and critiqued constantly, and every rabbi in America has had a little taste over the last few years of that weight.”
While the interaction carried an unexpected emotional weight for Heydemann, it also came with a distinctive Jewish Chicago touch: a White Sox-themed kippah.
She said she included the kippah, which featured the Chicago White Sox logo on the exterior as well as a pomegranate on the inside, in a chest of Chicago-themed gifts presented to the pope on Thursday during the visit as a nod to his lifelong devotion to the baseball team.
“We thought that would be a sweet point connection between me and the pope,” Heydemann said, adding that the pontiff’s typical white zucchetto looks “awfully like a kippah.”
“It brings us all joy to imagine that after a long day at work wearing the cream-colored one that matches his robes, maybe at the end of the day he’ll switch it out for a jersey material, White Sox kippah, and thinks fondly of sweet home Chicago, and the Jewish spiritual community gave it to him,” Heydemann added.
A list of gifts that circulated in local media included another piece of Jewish paraphernalia: a tote bag with the words “Resisting tyrants since Pharaoh.” That’s a catchphrase from T’ruah, the rabbinic human rights group where Heydemann has been on the board. But the rabbi said the inclusion was an error: She was carrying the bag, not giving it to Leo.
Looking back on the meeting with the pope, Heydemann said her experience reflected a broader conviction about “building bridges, even in the presence of difference.”
“There’s too much at stake in our world for us to not be continuing to be in relationship with one another in the presence of differences,” Heydemann said.

Finalists announced for lucrative Jewish literary award
(JTA) — Amir Tibon’s memoir about his family’s ordeal during the Oct. 7 attacks on Israel and Laura Hobson Faure’s history of Jewish children who fled from Germany to France during World War II are among the finalists for the 2026 Sami Rohr Prize.
The annual award — which alternates each year between works of fiction and nonfiction and which honors emerging Jewish writers — is considered one of the most prominent awards in Jewish literature.
The winner of the award, which comes with a $100,000 prize, will be announced on June 16.
A panel of judges will decide among four nonfiction finalists for this year’s award. Since the prize was established in 2006 — the first award was presented in 2007 — Sami Rohr Prize panelists and advisors have included historian and diplomat Deborah Lipstadt, historian Jonathan Sarna and longtime Columbia University journalism professor Sam Freedman.
“What strikes me about this year’s finalists for the Sami Rohr Prize for Jewish Literature is the remarkable range of stories they tell and the depth of insight they bring to Jewish life and history,” Debra Goldberg, director of the Sami Rohr Prize, said in an email. “Each of the four books explores questions of memory, identity, displacement, resilience and responsibility through deeply personal narratives that feel both timely and enduring.”
The 2026 Sami Rohr Prize finalists are:
Laura Hobson Faure, “Who Will Rescue Us?: The Story of the Jewish Children who Fled to France and America During the Holocaust.” Faure is a professor of modern Jewish history at Université Paris 1-Panthéon-Sorbonne. Yale University Press, her publisher, describes “Who Will Rescue Us” as “the first comprehensive study of Jewish children’s flight from Nazi Germany to France — and their subsequent escape to America from the Vichy regime.” It is her second book.
Shaul Kelner, “A Cold War Exodus: How American Activists Mobilized to Free Soviet Jews.” A professor of Jewish studies and sociology at Vanderbilt University, Kelner’s second book details how American Jews transformed a largely overlooked human rights issue into a landmark 20th-century mass-mobilization effort.
Jordan Salama, “Stranger in the Desert: A Family Story.” Salama, an author and contributor to The New Yorker, National Geographic and other publications, traces his Jewish family’s history “from Moorish Spain and Ottoman Syria to Argentina and beyond.” A mix of travelogue, memoir, history and reportage, “Stranger in the Desert” is his second book.
Amir Tibon, “The Gates of Gaza: A Story of Betrayal, Survival, and Hope in Israel’s Borderlands.” The first book by the Israeli journalist is a first-person account of his family’s ordeal as residents of Kibbutz Nahal Oz, which was violently attacked by Hamas on Oct. 7, 2023. Alongside accounts of the day’s losses, Tibon also recounts the heroic efforts by his father, a retired major general, to race into the battle zone and rescue his son, daughter-in-law and two granddaughters from Hamas gunmen.
“As the Prize approaches its 20th year, I hope it will continue to support writers whose work expands our understanding of the Jewish experience and sparks meaningful conversation for generations to come,” Goldberg said. “I am immensely grateful to share in the Prize’s mission to honor excellence, nurture talent and connect Jewish voices across the globe.”
The Sami Rohr Prize, named for the late American real estate developer and philanthropist who fled Nazi Germany as a boy, is administered in association with the National Library of Israel. 70 Faces Media, the parent company of the Jewish Telegraphic Agency, is the prize’s media partner.

A decaying historic farmhouse finds a savior in Chabad
A Dutch Colonial home, just one of a handful of pre-Revolutionary War houses left in New York City, has been vacant and decaying for years. The windows are boarded up, signs warning against trespassing cover the property, and chunks of the ceiling are missing inside.
This historic landmark has an unlikely savior: Chabad, the global Lubavitch movement, which is planting one of its thousands of outposts there.
“Dilapidated is an understatement,” Rabbi Zalman Liberow of Chabad of Flatbush said as he gave the Forward a tour.
Chabad of Flatbush, led by Liberow and his wife, Chana, bought the historic Brooklyn property in December 2024 and will soon begin renovations to make the place livable. In the meantime, the couple has already transformed the barnhouse next door into a sanctuary, where a photo of the Lubavitch rebbe hangs on the wall near a compartment once used to store hay.
As other Jewish organizations have shifted toward digital community, Chabad has continued investing heavily in brick-and-mortar real estate, ranging from modest suburban homes to multimillion-dollar towers and converted landmarks. It’s a strategy that anchors Chabad in the communities it serves, but can also be costly: For the most part, Chabad couples — each unit headed by a rabbi and rebbitzin — finance their own operations, raising their own money to buy homes and establish centers of Jewish life.
The Liberows said a generous donation of Bitcoin from a donor, Eliot Stavrach, ultimately allowed them to purchase the 22,000 square foot lot for roughly $3 million, along with securing a high-interest loan to pay the mortgage while the couple awaited the sale of their old headquarters down the street. Last week, that transaction went through and reaped nearly $1.1 million.
The seller had also cut the asking price by nearly half, offloading what had become a white elephant, Liberow said.
“For him, it was a pain. For us, it was good,” Liberow said. “And I thought, even better, this is such an important piece of United States history.”
The prior landlord had reportedly struggled to find a buyer for the landmarked home, which by law cannot be demolished, and any alterations to the facade must be pre-approved by the city Landmarks Preservation Commission. In buying the home, the Liberows are also preventing its further deterioration — to the relief of neighbors who said the abandoned site had become a hotspot for drug use and a symbol of neglect.
“I’m just happy that the house will not be torn down and will actually have a future — a good one, it seems,” said Lori Citron Knipel, a former leader in the Brooklyn Democratic Party who used to frequent the house. “So that absolutely warms my heart, because it’s been breaking every time I pass it.”
The house’s history
The Wyckoff-Bennett Homestead is likely among the ten oldest properties in Brooklyn and the 50 oldest houses in all of New York City, according to Simeon Bankoff, former executive director of the Historic Districts Council.
A 1968 report from the Landmarks Preservation Commission noted that “two hundred years of wear have done little to diminish the simple beauty of its clear-cut profile,” and described it as “the most beautiful example of Dutch Colonial architecture in Brooklyn.”
The house is also notable for its role in the Revolutionary War: During the conflict, it quartered German soldiers fighting for the British, known as Hessians. Two of the soldiers etched their names and units into a windowpane.
A historical marker at the house notes that those troops may have taken part in the Battle of Brooklyn, the first major battle after the signing of the Declaration of Independence.
According to Liberow, local legend holds that George Washington once stopped at the Wyckoff-Bennett house for tea — though, “we never did find the teacup,” he joked.
Bankoff attributed the properties’ staying power partly to the fact that prior to a venture called 22nd Street Investors LLC purchasing the lots in 2021, the property had only ever been owned by three families over more than 250 years.
Hendrick H. Wyckoff, son of a Dutch settler who emigrated to New Amsterdam in 1637, is believed to have built the house before 1766. In 1835, Cornelius W. Bennett purchased it, and it remained in the Bennett family for four generations before a Jewish couple, Annette and Stuart Mont, bought the property in 1983.
‘A piece of Brooklyn’s history’
The Monts had a deep appreciation for the home’s history, Citron Knipel said, and often opened it to the community. They hosted political fundraisers, birthday parties, and even a wedding at the house, she said, and they welcomed school groups into their home for local history field trips.
Only the facade of the house is landmarked, making its preservation legally required. But the Monts also preserved its interior details, including furniture from the Wyckoffs and Bennetts, an ornate fireplace framed by decorative tiles depicting biblical scenes, and an antique Richardson & Boynton Co. stove.
“There’s a sense of being part of and having a responsibility to the rest of the community to preserve it and move it forward,” Stu said in the 2013 documentary Living in a Landmark.
“And share it,” Annette added. “Because we have bought a piece of Brooklyn’s history.”
But an effort to secure the home’s legacy fell apart in 2010. The Monts had been in talks with the city to purchase the property, only to withdraw after the city reduced the sale price, deducting the rent the Monts theoretically would have paid to continue living there.
Annette died in 2013 at age 72, and Stuart died three years later at age 76. Their children, Ira and Randi Mont, sold the property to 22nd Street Investors LLC, registered to real estate investor Avraham Dishi, in 2021.
In an interview with the Forward, Ira Mont said he believed at the time of sale that 22nd Street Investors LLC would keep the house in good condition — and was disappointed that they ultimately did not.
Dishi drew two complaints for failing to maintain the Wyckoff Bennett house: one for the poor condition of the fence, still active, and another for the condition of the facade and roof, later withdrawn.
Officials at a Landmarks Preservation Commission hearing in March to discuss the Liberows’ minor proposed changes to the home noted there had been “all kinds of vandalism, fires, squatters, [and] drug users” there in recent years.
The Forward reached Dishi’s office by phone and left a message, but did not hear back.
Liberow said he has big plans for the house pending approval from the Landmarks Preservation Commission, including displaying a video in the front yard highlighting Jewish history in the United States. The Commission has already approved plans to install porch railings, a curb cut and a driveway at the site. And like the Motts, the couple plans to open the space up to the public. They’ve already begun hosting Hebrew school and holiday gatherings in the barnhouse next door, which they renovated for about $200,000 with rustic touches including wood paneling, barrels, lanterns and candle chandeliers.
For neighbors, the most meaningful change may simply be that the property is occupied at all.
“We got a very big welcome over here, because everyone’s so happy,” Liberow said. “Someone is going to save the property.”
