Abraham Zarem, one of the last surviving Manhattan Project scientists, dies at 106

(JTA) — Abraham Zarem was 28 when he joined the Manhattan Project, the vast U.S. government effort to develop the atom bomb.

Engineers like him gathered in secret laboratories in New Mexico, California, New York City and elsewhere to provide the practical know-how the theorists lacked.

“‘They were geniuses, but didn’t know how to build a f—king thing,’” Zarem recalled, according to his longtime rabbi at Sinai Temple in Los Angeles, David Wolpe. 

Zaum, who went on to a distinguished career in technology, business development and leadership management training, died March 8 in Los Angeles. He was 106, and one of the last surviving members of the army of scientists, technicians, bureaucrats and clerks who helped build the weapon that would force Japan’s surrender in World War II and usher in the Atomic Age. 

After the war, Zarem joined the staff of the United States Naval Ordnance Test Station at Pasadena, where as head of the electrical section of the physical research division he developed a high-speed camera used to study intense light sources and other phenomena. Popular Mechanics called the Zarem camera — 25,000 times faster than any movie camera then available — a “miracle.”

In 1963, Zarem served as senior vice president of Xerox, leaving in 1970 to launch a consulting business. He returned to Xerox as founder and CEO of its Xerox Development Corporation in 1975. He later served as founder and managing director of Frontier Associates, a technology consultancy. 

Born in Chicago on March 7, 1917, Zarem was valedictorian of his undergraduate class at the Armour Institute of Technology (now the Illinois Institute of Technology), and earned his doctorate on the physical properties of the electric spark at the California Institute of Technology. He headed the Stanford University Research Institute in Los Angeles while still in his 30s.

Later he served as distinguished senior advisor for Neuroscience Technology Transfer for the UCLA Brain Research Institute and a member of the Urology Advisory Board of the UCLA Geffen School of Medicine. Additionally, he served as distinguished visiting executive in Science and Technology for Caltech’s Jet Propulsion Laboratory.

One of Zarem’s companies, Electro-Optical Systems, developed the “world’s first practical ion engine” — an experimental high-energy thruster for spacecraft. It now resides in the Smithsonian Institute in Washington, D.C.

Zarem was also a regular at Temple Sinai, where Wolpe said Zarem mentored him as a young rabbi. Zarem and his wife Esther were generous contributors to the congregation; Wolpe remembered Zarem chanting from the book of Jonah on Yom Kippur when he was 99.

“Abe Zarem was a brilliant, buoyant, passionate, pious and philanthropic person,” Wolpe told the Jewish Telegraphic Agency this week. “He had a central role in some of the key scientific events of human history — the atomic bomb, the moon landing — and yet took an interest in everyone lucky enough to meet him. Abe was truly yachid b’mino — unique in his time. He will be greatly missed.”

Unlike with some of his collaborators on the Manhattan Project, there is no public record of Zarem grappling publicly with the moral implications of the weapon he helped develop. Years after their war work at Caltech, a man who worked under Zarem as a lab assistant said he felt no guilt, because without the detonations at Hiroshima and Nagasaki, he told a local newspaper, “We would have lost 500,000 Americans in the invasion of Japan.”

But Zarem did go on the record in 1952 on a different topic, in advice he shared with a labor and management magazine: “Keep your feet warm, and your head cool. And watch out for the hotheads with cold feet.”

His survivors include his children, Janet, David and Mark.

Democrats leader Golan approached by man with knife on Israeli election day

(JTA) — JERUSALEM —  Israel Police arrested a man carrying a large knife after he approached Yair Golan, head of the Democrats party, as Golan was campaigning in Tel Aviv on Election Day.

“Contrary to reports, no stabbing attempt occurred,” the police spokesman said in a statement.

The police said officers at the scene noticed a “suspicious object” protruding from beneath the coat of a man standing nearby. When they stopped him for inspection, they found a knife in his possession.

In a statement, Golan’s party said the man approached Golan “in a threatening manner” and that “when Golan’s security guards blocked him, a large knife slipped from beneath his clothing and fell to the ground.”

Police described the suspect as a Jerusalem resident in his 20s. He was arrested and taken to a local police station for questioning. They said the investigation “is ongoing.”

Following the incident, Golan said “incitement and violence will not deter us.” In a statement to the press he blamed the attack on Prime Minister Benjamin Netanyahu’s negative campaigning and highlighted the ties between one of his spokespeople and Qatar.

“This is the direct result of the poison machine operated by Netanyahu and his Qatari agents. I call on everyone who cares about security and democracy to go out and vote now, so that we can ensure the country we love so dearly becomes a free and safe place once again,” Golan said.

Rebellion PAC’s antisemitic political ad could incite violence against Jews

Israel did not cause high grocery prices in America.

Israel is not the reason you don’t have free universal healthcare.

But a new political ad from Rebellion PAC depicts struggling young parents grocery shopping in Michigan and putting back a dozen eggs because of U.S. military aid to Israel, saying they can no longer afford basics like bananas because they are funding healthcare in Israel. The ad ends by saying Republican Senate candidate Mike Rogers is for “them” — Democratic candidate Abdul El-Sayed is for you.

Rebellion PAC, an independent entity that legally cannot coordinate with campaigns or parties, is proudly promoting a political ad that is deeply misleading, inflammatory and dangerous for American Jews. The ad uses classic tropes blaming Jews for economic and social woes, the same propaganda used historically by antisemitic regimes in Nazi Germany and the USSR. The target in this ad is the Jewish state, but the familiar subtext remains: your family is suffering because Jews are taking your money.

This would be antisemitic in any context, but in the current climate it is wildly irresponsible. American Jewish communities are facing unprecedented domestic terror threats and a historic crisis in antisemitism.

In Michigan, where this ad is aimed at voters who may decide control of the U.S. Senate, an armed domestic terrorist drove a car packed with improvised explosives into Temple Israel. The intent was a mass casualty event aimed at killing as many Jews as possible, including the children in the preschool. Brave security team members stopped the attack, but the attacker was only a few feet from perpetrating what could have been the deadliest terror attack on U.S. children since Oklahoma City.

American Jews make up only 2% of the population, but according to the FBI, Jews made up 63% of religion-based U.S. hate crimes in 2025 — and roughly 14% of all reported hate crimes.

Every candidate across the spectrum, including El-Sayed and Rogers, should disavow and condemn the dangerous rhetoric in this ad. This ad takes real problems — the exploding cost of groceries and healthcare — and blames them on Israel. This is classic antisemitic propaganda.

El-Sayed’s campaign distanced itself from the ad without condemning its content.

“This ad is not affiliated in any way with the Abdul for Senate campaign,” El-Sayed campaign spokesperson Roxie Richner said in an emailed statement. “Abdul is focused on pushing back against Trump’s agenda that is raising prices for Michiganders. No one speaks for Abdul but himself and his campaign.”

It’s worth noting that the El-Sayed campaign did not disavow the content of the ad and only issued a statement via email. El-Sayed himself did not issue a public stance on social media or criticize the inflammatory and dangerous content of the ad. His response is wholly inadequate—it does nothing to confront the antisemitism in the ad, it simply points out his campaign did not make it.

Contrast this with his former opponent, Rep. Haley Stevens, who lambasted the ad on X, stating, “This type of fearmongering about Israel is wrong.” she went on to say, “Do we need to lower costs by building more homes, securing people’s health care, and creating a fairer federal tax code? Yes, we do!! How we do so is not by blaming the high costs of our goods on the only Jewish homeland in the world.”

El-Sayed should unequivocally condemn this ad and its content, not just distance himself from it. Every candidate should stand firmly against antisemitic rhetoric in electoral politics.

When bad actors tell people their economic problems are caused by Israel, it inevitably creates a dangerous situation for Jewish Americans. Though public opinion polls show falling support for the Jewish state, it’s difficult for Americans to take those frustrations out on Israel directly, so local American Jews become a convenient target for their misplaced anger. This is exactly what happened in Michigan at Temple Israel. A Hezbollah sympathizer took his anger on Israel out on the local Jewish population.

Americans are facing real issues. But Israel is not the cause. Our grocery bills are higher for a variety of complex reasons. Grocery inflation started during the pandemic with disrupted supply chains. Production costs have risen. Russia’s invasion of Ukraine raised global grain prices. Bird flu drove up the price of eggs. Tariffs have also impacted food prices.

In terms of healthcare, a Nov. 2025 Gallup poll found that 46% of Americans preferred a government-run healthcare system, while 48% preferred a system based mostly on private health insurance. Cutting or ending U.S. military aid to Israel would not change the fact that  Americans are deeply divided on how we should address our healthcare systems’ deep-seated problems. That would require American lawmakers to agree on and enact changes to how our own system is financed and organized. This is an issue of political philosophy — not lack of funds. Israel is not preventing the U.S. from organizing or financing our own healthcare system. Ending military aid to Israel would neither reverse those food-price pressures nor establish universal healthcare. The ad offers struggling Americans a scapegoat for their hardships—and American Jews face the danger of being treated as that scapegoat’s local representatives.

Rebellion PAC’s co-founder and former Executive Director Brianna Wu decried the ad, stating, “I would have quit as executive director rather than produce this,” calling the ad “awful.” We should all follow her example.

Candidates, thought leaders and elected officials must all come together and condemn this dangerous and antisemitic ad. American Jews are already being discriminated against, attacked, and in severe cases, murdered by people who hold them responsible for Israel. Political leaders must reject rhetoric that puts an even larger target on our backs by turning us into scapegoats for America’s economic struggles and healthcare failures.
