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.

How New York Jews made pickles a big dill
The Pickled City: The Story of New York Pickles
By Paul van Ravestein and Monique Mulder
Chronicle Books, 224 pages, $27
“Pickles are a favorite food in Jewtown,” muckraker Jacob Riis, referring to the Lower East Side, wrote in How the Other Half Lives, his seminal exposé on poverty. “They are filling and keep the children from crying with hunger. Those who have stomachs like ostriches thrive in spite of them and grow strong — plain proof that they are good to eat.”
Other thinkers from the turn of the last century disagreed, one lamenting, of the children of New York who got their meals from pushcarts, “it speaks volumes for their digestive powers that they don’t die at once.” That was Teddy Roosevelt.
But appropriately for a preserved foodstuff, pickles have had a remarkably long cultural shelf life. The Pickled City: The Story of New York Pickles, a new coffee table book about the ubiquitous cukes, reaches deep into the barrel to chronicle the rise of the pickling industry, giving pride of place to the Jewish immigrants who sealed the business for posterity.
The book is the work of Paul van Ravestein and Monique Mulder of the Dutch branding company Mattmo, and is a successor to their previous book De Zure Stad (The Sour City) about the pickle history of the Netherlands, pioneered by a different set of Jewish immigrants who were, overwhelmingly, murdered in the Shoah.
The Pickled City is a brighter work, though in the early going its emphasis on Jews, stated early and often, is a bit of a head scratcher. Going back to Mesopotamia for early pickling practices, and outlining the largely gentile-owned pickle businesses in the U.S. (the first American pickle outfit, the William Underwood Company, trademarked devilled ham) the Jews appear to be relative latecomers. It was Dutch settlers in what was then New Amsterdam who kickstarted the process of farming and preserving cucumbers.
An earlier wave of German immigrants brought pickle culture to Manhattan before Eastern European Jews took to their pushcarts. But the Jews brought a piquant innovation to their pickles, brining them not in vinegar, but salt water with dill and garlic: the kosher pickle we all know. That variety soon became a bestseller even among the goyische operations like Heinz, a business that was early to apply for kosher certification.
The Jewish love affair with pickles was itself not novel. The Talmud mentions pickled veg as a symbol of abundance and survival and, per van Ravestein and Mulder, the “transformation through pickling — turning a simple, earthy root into a tangy, vibrant dish — was often seen as a metaphor for renewal and the endurance of the Jewish people through adversity.”
We see the enterprise, in pages of archival photos and maps of the pickle shops of yesteryear alongside long-running institutions like Russ & Daughters and Katz’s.
At times, beyond the handsome packaging of the book, the branding agency origins of the authors stick out: A primer on B&G pickles reports their $2.16 billion in net sales, and calls it a “testament to entrepreneurial spirit and innovation in the food industry.” But there are just as many colorful stories that don’t read like investor reports.
We learn, for instance, that Izzy Guss, of Guss’ pickles, beat out the competition after a neighbor in his tenement offered to hook his cart up to electricity with an extension cord, giving the cart a light and allowing Guss to sell at night. (We’re told the cord was cut when Guss refused to marry the neighbor’s daughter.)
The book also touches on the pickling history of Long Island, with a mention of a Samuel Ballton — Pickle King of Greenlawn, a formerly enslaved man and Union veteran who produced 1.5 million pickles in a single season. The industry in Syosset was dealt a major blow with a blight called the “white pickle” disease, and subsequently pivoted to potatoes.
Even with these New York histories, the book often crosses Delancey into a wider world, making a kumbaya case for pickles as a conduit for cultural exchange.
Japanese pickled plums, Indonesian atjar and Indian chutneys are given space toward the back, but their current imprint in New York, on the same streets that once held tenements and peddlers, is oddly glossed over. (I could have tipped them off to the Astoria bagel shop that serves beef bulgogi and kimchi sandwiches.)
“For Jewish families fleeing persecution, pickling was more than a way to save food — it was a way to preserve identity and heritage,” the authors write.
This is not an exclusively Jewish phenomenon. There are 8 million stories in the pickled city. This book cracks the lid, but only skims the surface.

Israeli-American soldier Moshe Katz, killed in Lebanon rocket strike, laid to rest on Mt. Herzl
(JTA) — Hundreds gathered on Sunday night at Israel’s military cemetery on Mt. Herzl for the funeral of Moshe Yitzchak Hacohen Katz, an American-born Israeli soldier who was killed by a rocket strike on Saturday in southern Lebanon.
Katz, 22, from New Haven, Connecticut, is the fifth Israeli soldier killed in Lebanon since Hezbollah, an Iranian proxy in Lebanon, resumed attacks on Israel following a 2024 ceasefire, after Israeli and U.S. strikes on Iran last month.
“With unspeakable tragedy I regret to inform you that my 22 year old son Moshe Yitzchak a*h a sergeant in the idf, fell in battle in Lebanon,” Katz’s father, Mendy, wrote in a post on Facebook on Saturday. “My oldest Son with a zest for life and jokes. Burial is tomorrow in israel. Maybe we only share good news. My heart is shattered and the wound is real.”
Mendy Katz had been in Israel when the war began and posted on March 7 about witnessing his son’s graduation from basic training with the Israel Defense Forces before returning to the United States via Egypt.
During the funeral on Sunday, Katz, who was posthumously promoted from corporal to sergeant and was affiliated with Chabad, was eulogized by a host of fellow soldiers who referred to him as a “true friend” who “always used to make sure that anyone around him was always taken care of.”
“Moshe was a brave soldier, we have proof of that, but more than that, he was a loyal friend, he was a hard-working son and a loving, caring brother,” Adina, Katz’s sister, said between tears during her eulogy. “Moshe’s body might be gone, but his legacy is not. He was a proud soldier and a proud Jew, and we are the proudest family.”
Israeli Prime Minister Benjamin Netanyahu offered condolences to Katz’s family in a post on X and wished a speedy recovery to three other soldiers moderately wounded in the attack.
“Moshe z”l immigrated to the land from the United States, enlisted in the Paratroopers Brigade, and fought bravely for the defense of our homeland,” Netanyahu wrote. “On behalf of all Israeli citizens, we embrace Moshe z”l’s family in this difficult hour and wish a swift and complete recovery to our fighters who were wounded in that incident.”
On Sunday, Netanyahu announced that he had instructed the Israeli military to further expand its operations in Lebanon in order to “finally thwart the threat of invasion and to push the anti-tank missile fire away from our border.”
Menachem Geisinsky, a photographer and friend of Katz’s, also eulogized him in a post on Facebook, writing that he “forever will be my hero” for “his bravery in coming all the way from New Haven, Connecticut to fight for what he believed was right and also for being a man who wouldn’t tolerate a frown.”
“So be like Moshe. Be a hero. Make someone’s day. Make someone giggle or smile,” wrote Geisinsky. “Step up, and be the man Moshe was, and forever will be remembered as.”
Katz is survived by his parents, Mendy and Devorah Katz; siblings Adina, Yehuda, Shua and Dubi; and grandparents.

A second poll of US Jews finds the same result: Most oppose the war in Iran
(JTA) — For the second time in a day, a nonpartisan poll has found that most American Jews oppose the U.S. military campaign against Iran — even as 90% of them say they oppose the Iranian regime.
The new poll, conducted by GBAO Strategies on behalf of the liberal pro-Israel lobby J Street, found that 60% of U.S. Jews say they oppose “the US military action against Iran.”
About the same proportion, 63%, said they believed “the most effective way to address U.S. and Israeli concerns about Iran’s nuclear program and destabilizing regional actions is through diplomacy and sanctions,” not military action.
And the majority of American Jews said they believed the war will not improve Israel’s security, with a third saying they believe the war will weaken Israel’s security.
As with the previous poll released earlier on Monday, the poll found a sharp partisan and denominational split in the results, with Republicans and Orthodox Jews more likely to support the war, which the United States and Israel jointly launched on Feb. 28.
A press release from J Street touted the survey as “the first methodologically sound poll of Jewish American opinion since the conflict began,” positioning the results as an antidote to findings from the Jewish People Policy Institute, which surveys “connected” U.S. Jews and has found that a majority of them support the war, even though the proportion has fallen since the war’s start.
“This data is a wake-up call for anyone claiming to speak for the American Jewish community while beating the drums of war,” J Street President Jeremy Ben-Ami said in a statement. “Most American Jews see this war for what it is: A reckless, unforced error by a President who has no clear, achievable goals or an exit strategy. This poll proves that the ‘pro-Israel’ position is the pro-peace position – and that means stopping this war before more lives are lost.”
The survey of 800 Jewish registered voters was conducted March 24 to 26 and has a margin of error of 3.5 percentage points.
The J Street survey also asked respondents about other issues related to Israel. It found that 70% of U.S. Jewish voters said they are more sympathetic to the Israelis than the Palestinians in the Israeli-Palestinian conflict, compared to multiple polls finding an even split or slight edge for the Palestinians among Americans overall.
It also found that 70% of American Jews oppose unconditional military and financial assistance to Israel — reflecting a mounting political consensus that is at odds with the priorities of AIPAC, the traditional pro-Israel lobby.
