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.

Trump announces deal with Iran is ‘now complete’
(JTA) — President Donald Trump announced Sunday that a deal to end the war with Iran and reopen the Strait of Hormuz is “now complete.”
“Congratulations to all! I hereby fully authorize the toll free opening of the Strait of Hormuz, and, simultaneously herewith, authorize the immediate removal of the United States Naval blockade,” Trump wrote in a post on Truth Social. “Ships of the World, start your engines. Let the oil flow!”
Pakistani Prime Minister Shehbaz Sharif, who has played a key mediating role in talks between the U.S. and Iran, also announced that a deal had been reached minutes before Trump made his post, adding that an official signing ceremony would take place Friday in Switzerland.
“Both sides have declared the immediate and permanent termination of military operations on all fronts, including in Lebanon,” Sharif wrote in a post on X.
The announcement comes more than three months since Israel and the U.S. launched its joint strikes on Iran in February. While the deal’s details have not yet been publicly announced, it is expected to extend a ceasefire between Iran and the U.S. for 60 days, during which the countries will negotiate a broader agreement addressing Iran’s nuclear program.
Israeli Prime Minister Benjamin “Bibi” Netanyahu did not immediately put out a statement following the announcement, but earlier Sunday he had posted a message on X celebrating Trump’s birthday.
Also earlier Sunday, Israel launched strikes on Hezbollah targets in Beirut, prompting Iran to vow retaliation and drawing a sharp rebuke from Trump, who said the strikes had “delayed the signing by a few hours.”
“Why did Bibi have to do a f–cking attack? I was so pissed off. I let him know. He has no fucking judgement. I let him know that,” Trump told Axios Sunday.

Jane Yolen, children’s book author whose ‘The Devil’s Arithmetic’ became a Holocaust classic, dies at 87
(JTA) — Jane Yolen was already an award-winning author and illustrator of more than 100 titles for young readers when her editor suggested she write a Jewish children’s book.
At first, she resisted the idea. Sure, she was Jewish. But she didn’t grow up in a religiously observant family, and she insisted she didn’t know enough about Judaism to take on the project.
Finally, she relented. Drawing on a spark of an idea about a Holocaust time-travel fantasy, Yolen turned in the first draft of what would become “The Devil’s Arithmetic,” her 1988 young adult novel. “I thought, ‘OK, I’m going to try this,’” Yolen recalled to the Jewish Telegraphic Agency years later.
The book won immediate acclaim and garnered multiple awards. Today, it’s seen as a classic of the genre — and one that remains caught up in banned-book lists.
For Yolen, who died Thursday at 87 in her home in Western Massachusetts, “The Devil’s Arithmetic” became her signature title. Still in print, the book was also made into an Emmy Award-winning Showtime feature starring Kirsten Dunst. It was the cornerstone of a titanic legacy in children’s literature, her family said in a statement.
“It is with profound sadness that I, along with my brothers, Adam Stemple, and Jason Stemple, share the news of our mother, Jane Yolen’s passing,” her daughter Heidi Stemple wrote on Facebook, adding that Yolen had “passed gently with no pain or stress” and her family by her side, reading one of her books to her.
Yolen was born on Feb. 11, 1939, in New York City. Her father was a journalist and her mother was a psychiatric social worker until Yolen was born.
An alumna of Smith College, where she won poetry and journalism awards, she worked first as an editor in New York City, writing at her breaks and time off. Her first published book, “Pirates in Petticoats,” a nonfiction work about women on the high seas, was published when she was 22.
She soon pivoted to children’s literature, becoming one of the most prolific authors in the genre. She went on to publish 450 children’s books, including more Jewish titles, and was known as “the Hans Christian Andersen of America.” She won the prestigious Caldecott Medal for her 1987 picture book, “Owl Moon,” and her “How Do Dinosaurs …” series is a staple in many preschool classrooms. (It includes one Jewish title: “How Do Dinosaurs Say Happy Chanukah?” Her 450th title was published just this year, her children said.
But it was “The Devil’s Arithmetic,” scholars have said, that cemented her legacy as a leading author for young Jews. The novel was a trailblazer for its blending of time-travel with historical veracity, according to the late Norman H. Finkelstein, a National Jewish Book award winner who was a children’s librarian himself.
“It was a different Holocaust book,” Finkelstein told JTA in 2018, on the occasion of the title’s 30th anniversary. “It was not strictly factual, it was not a memoir. Jane did a superb job in taking the story of the Holocaust down to a level that ordinary American kids could understand. The characters were realistic, not paper cutouts.”
Other titles of hers included “Meet Me at the Well: The Girls and Women of the Bible,” with Barbara Diamond Goldin, and “Jewish Fairy Tale Feasts,” with her daughter Heidi, who developed and illustrated the hands-on recipes.
Yolen relished the collaborations with her daughter. They lived next door to each other, along with Stemple’s family, with two grandchildren who were taste-testers of Stemple’s recipes.
“Jane was a treasure, and it is difficult to think of the world of books — indeed the world itself – without her,” Richard Michelson, an award-winning author of Jewish children’s books and Yolen’s friend and neighbor, wrote on Facebook. Describing her as a cherished mentor of younger writers, he added, “Jane created classics as if it were as easy as breathing.”
While often assigned in schools as part of lessons on the Holocaust, Yolen’s titles are not without controversy. In 2025 a Texas school district, using artificial intelligence, flagged “The Devil’s Arithmetic” for removal as a title containing “DEI,” or diversity, equity and inclusion content. The book became one of several well known Holocaust titles to be pulled from schools in the last few years.
Though she had initially resisted the idea of being a Holocaust author, Yolen would go on to publish a trilogy of unconventional young-adult novels about the subject. She incorporated elements of “Sleeping Beauty” into 1992’s “Briar Rose.” “Mapping the Bones” followed in 2018 as a riff on “Hansel and Gretel.”
“Whenever we think of the Holocaust, we think of remembering,” Yolen told JTA in that same 2018 interview. “We think of never forgetting. Soon all we will have are the stories.”
In addition to her children, Yolen is survived by six grandchildren. Her husband, David Stemple, to whom she was married for 44 years, died in 2006.

Hebrew Union College claims Ohio’s charity-law suit violates its First Amendment rights
(JTA) — The Reform movement’s central rabbinical seminary filed a motion to dismiss the state of Ohio’s lawsuit against the school Friday, claiming the suit violates “foundational Jewish religious doctrine.”
It was the latest escalation in a pitched battle between Hebrew Union College and the state attorney general’s office, which has accused HUC of violating nonprofit law by shuttering degree-granting programs on its historic Cincinnati campus.
The suit, HUC argues, “violates the First Amendment by entangling government and religion.”
The suit was originally filed in April by then-Ohio AG Dave Yost — his second against the college related to its controversial plan to wind down its Cincinnati operations in favor of its New York and Los Angeles campuses. Yost claimed HUC’s actions in Cincinnati misled its donors by leaving a city where they were actively fundraising to support operations, and also violated its charter, which states that the school would “permanently maintain” a residence there.
The state seeks to seize HUC’s assets in Ohio and redirect them to a new, yet-to-be-decided nonprofit with a similar mission; an upstart rabbinical school founded by HUC alums says it wants them.
Such a move “is an unconstitutional and illegal governmental assault upon religion,” HUC’s strongly worded motion reads.
It continues, “The Attorney General has no role in dictating the religious affairs of institutions like HUC. The Court should reject his overreach into religious matters and should dismiss the Complaint because it is unconstitutional and unlawful.”
HUC also argues its vote to shutter the Cincinnati campus was done in full compliance with the law, adding that it intends to maintain the campus’s other assets, including the Klau Library, the American Jewish Archives and the Skirball Museum. In addition, citing a passage in the Torah that states “God will come to his people wherever they welcome him,” the school argues that considering “Jewish demographic realities” is part of its religious mission.
“These decisions were made thoughtfully and responsibly to ensure the long-term success of the institution and our ability to continue graduating strong Jewish leaders,” HUC president Andrew Rehfeld said in a statement accompanying the motion. The lawsuit, he added, “improperly seeks to interfere in the decisions of a religious organization, and this cannot be allowed to go unchallenged.”
Yost himself resigned as AG this week to join the Alliance Defending Freedom, a conservative Christian legal group that, in 2022, represented a Tennessee adoption agency that refused to foster a child to a Jewish couple. The suit against HUC continues under the state AG’s office.
