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.

Anti-BDS order will test Mamdani on day one
Outgoing New York City Mayor Eric Adams is immediately testing his successor’s position on the boycott Israel movement as Zohran Mamdani takes office, at a moment when the city’s Jewish community remains divided over the next mayor’s priorities and his stance on Israel.
On Wednesday, Adams signed an executive order barring city agencies from participating in Boycott, Divestment and Sanctions efforts, which would pre-empt any moves by city officials to divest from Israel Bonds and other Israeli investments. Mamdani, a strident critic of Israel, has pledged to end the city’s decades-long practice of investing millions in Israeli government debt securities and has said he would order the arrest of Prime Minister Benjamin Netanyahu if he visits New York.
Mamdani’s transition team had no immediate comment.
But Adams was prepared for a response. “If the incoming administration wants to reverse” the executive order, then “that is on their watch,” he said.
Why ban BDS now?
Adams announced the measure in remarks at the North American Mayors Summit Against Antisemitism, organized by the Combat Antisemitism Movement, in New Orleans, Louisiana. “You are being targeted,” Adams said. “And we have to be as intelligent and as focused, as strategic as possible. … That’s why I am signing an executive order today to deal with BDS, so we can stop the madness that we should not invest in Israel.”
Fabien Levy, the deputy mayor for communications, said the move, weeks before Adams departs, was “a flag in the ground” to state that the current administration “will not waver in the fight against antisemitism.”
New York City is home to the largest concentration of Jews in the United States. Many Jews view the bonds as a bulwark against the BDS movement, whose co-founder has stated that the goal is to apply economic pressure on Israel to end its occupation of the West Bank and to abolish Israel as a Jewish state.
The city’s investment in Israeli bonds was a flashpoint in the Democratic primary for mayor and in the general election. Mamdani, who co-founded the Students for Justice in Palestine chapter at Bowdoin College, pledged to publicly back the movement to boycott Israel. In an interview with the Forward in April, Mamdani said he would end Adams’ policies that he regarded as a violation of international law and human rights.
The city’s Jewish voters split in the competitive mayoral election last month — with former Gov. Andrew Cuomo receiving the support of most voters who identify as Jewish and dominating in Hasidic and Orthodox strongholds, while Mamdani got 31% of the vote and swept progressive Jewish neighborhoods in Brooklyn and Manhattan on his way to a citywide win. A recent poll of 745 American Jews by the Jewish People Policy Institute found that 64% of respondents view Mamdani as both anti-Israel and antisemitic, and 67% believe his election would make New York City’s Jews less safe.
Nonetheless, Mamdani’s positions on BDS and stance on the Israeli-Palestinian conflict resonated with a plurality of voters. Nearly half of Mamdani voters, 49%, said his position was a factor in their support, according to a CNN exit poll.
Levy, who is Jewish and accompanied Adams both on his four-day farewell trip to Israel and to Louisiana, said that the mayor is sending a message about what the city’s values are, “even if hating Israel has suddenly become ‘the cool thing’ by some.” In meetings and public remarks during his swing in Israel, Adams pointed out that Mamdani won with 50.4% of the vote, and that his policies were not popular. Mamdani met with Adams at Gracie Mansion earlier this week, a meeting that was kept private.
Mamdani will also have to decide whether to disband the recently-created mayor’s office to combat antisemitism, which has pursued a measure adopting the controversial International Holocaust Remembrance Alliance definition of antisemitism, which considers most forms of anti-Zionism as antisemitic. He’ll also need to decide whether to take action on Adams’ new New York City–Israel Economic Council, an initiative to strengthen economic ties with the Jewish state.
What the executive order says
Adams’ anti-BDS order bars agency heads, chief contracting officers and other mayoral appointees with contracting authority from adopting practices that discriminate against Israel or Israeli citizens. It also directs the city’s chief pension administrator and pension trustees appointed by the mayor not to support divestment from Israel Bonds or other assets.
Brad Lander, the outgoing city comptroller overseeing pension fund investments and a Mamdani ally, ended the city’s half-century practice of investing millions in Israeli government debt securities in 2023 when the holdings matured.
At the time, the city’s pension funds held $39 million in Israel Bonds, with a roughly 5% return. Lander, who is Jewish, maintained that he was following the city’s policy of avoiding foreign sovereign debt, treating Israel the same as other countries rather than giving it special treatment in the pension portfolio.
City pension funds also held more than $315 million in Israel-based assets, including nearly $300 million in common stock and over $1 million in Israeli real estate investment trusts.
Mark Levine, the comptroller-elect who is also Jewish, pledged to repurchase the bonds as part of the city’s portfolio. “This has been a rock-solid investment for decades,” he said. “Israel has never missed a bond payment, and a good, balanced portfolio should have global diversity.”

Senate Foreign Relations Committee advances Yehuda Kaploun as antisemitism envoy, with some dissent
(JTA) — Rabbi Yehuda Kaploun moved a step closer to becoming the next U.S. antisemitism envoy on Wednesday, as the Senate Foreign Relations Committee voted to advance his nomination in a divided 14-8 tally that reflected the partisan tensions surrounding his bid.
All 12 committee Republicans supported Kaploun, while only two Democrats — Sen. Jeanne Shaheen of New Hampshire and Sen. Jacky Rosen of Nevada — joined them.
Kaploun, a Chabad rabbi, businessman and 2024 Trump campaign surrogate, used his November confirmation hearing to highlight his personal encounters with antisemitism and to emphasize education, particularly about the Holocaust, as the central tool for combating hatred.
But Democrats focused instead on the administration’s approach to right-wing antisemitism, pressing Kaploun on Trump’s failure to denounce the extremist influencer Nick Fuentes after a recent interview conducted by Tucker Carlson. Kaploun avoided direct criticism of Trump, stressing free speech principles while asserting that the administration “is clear in condemning antisemitism.”
The vote came two weeks after 18 House Democrats urged the Senate to reject Kaploun’s nomination, citing his past partisan comments and legal controversies previously reported by the Jewish Telegraphic Agency. Shaheen said Wednesday she remained concerned about those remarks but hoped Kaploun would “be above partisanship” if confirmed, according to Jewish Insider.
Speaking soon after the vote at the Combat Antisemitism Movement’s North American Mayors Summit in New Orleans, Kaploun framed the challenge in civic terms.
“Antisemitism is anti-American. Racism is anti-American,” he said. “Myself, the president, the secretary of state, and the entire administration are going to work tirelessly to make sure religious liberty, justice, and restoring respect for humanity for everybody is the goal.”

Campus Frontlines: Professors and Students Continue to Fuel Antisemitism

There may be a ceasefire between Israel and Hamas, but on university campuses globally, antisemitism has yet to end. The encampments that took up space both on the lawns of universities and on the front pages of newspapers may be gone, but the new form of antisemitism, one that student leaders and professors are driving, is not.
The top global universities are expected to train students to become the next leaders in society. That requires complex courses to be taught with accuracy and objectivity.
This is not the case at Princeton, however. One course, entitled Gender, Reproduction, and Genocide, is scheduled for the spring 2025-2026 semester.
Taught by Nadera Shalhoub-Kevorkian, the course is said to explore “genocide through the analytic of gender” and specifically will focus on the “ongoing genocide in Gaza.”

In the course, students will “engage reproductive justice frameworks,” suggesting that Israel is committing genocide by deliberately targeting institutions that would prevent women from becoming pregnant. However, this claim, spread by the UN, has no factual basis.
UN’s fake “genocide report” accuses Israel of intentionally striking Gaza Al-Basma IVF clinic to destroy embryos to “prevent births” and “destroy future of Palestinians.” This claimed attack is a key aspect of the claim. But there is ZERO evidence for any of it. Analysis: 1/ pic.twitter.com/t6n855r5an

The UN report relies on a 2024 ABC News story that claimed an IDF shell was deliberately fired at an IVF clinic in December 2023, allegedly destroying more than 4,000 embryos with the intention to “prevent births.”
But even ABC News and its sole source, who was not present at the time, could not verify that an IDF shell caused the damage. In fact, a wide-angle photo of the scene shows a nearby high-rise building visibly damaged, while the IVF clinic itself appears fully intact.
If the course’s entire framework being held up by falsified information wasn’t enough, it also seeks to compare the history of the “genocide” in Gaza to other genocides, including the Holocaust. There is no lack of moral clarity more evident than flattening the Holocaust into a political talking point. No comparison can be made between a war of defense and the industrialization of murder that the Nazis waged against the Jewish people.
Yet, this vile comparison does not come as much of a surprise, considering the professor herself has, in the past, denied the murder and assault of Jews.
Antisemitism from faculty is not limited to academic courses. A Students for Justice in Palestine (SJP) chapter at University College London hosted Samar Maqusi as part of a series titled “Palestine: From Existence to Resistance.” Although the lecture was advertised as a discussion on the origins of Zionism, Maqusi instead promoted classic antisemitic tropes, including that Jews require the blood of gentiles for making their “special pancakes,” referring to a medieval blood libel in which Jews use the blood of gentiles for making matzah.

Unfortunately, many discussions of Zionism on university campuses come from those with hostile and thus inaccurate beliefs on what it truly means to be a Zionist.
Even in an interfaith discussion at the City College of New York, a Hillel director was told he was “responsible for the murder” of Gazans and caused “disgust” in other participants because he was a Zionist. Activist and student groups further condemned the interfaith discussion. Not in favor of defending the Hillel director whose sole wrongdoing was being a Jew, but because interfaith efforts were causing the “normalization of Zionism.”
In warping the definitions to fit the narrative of the speaker or lecturer, lectures and campus spaces have become breeding grounds for bias and thinly veiled antisemitism.
Antisemitic Student Voices
Student leaders and activists have also frequently isolated their Jewish peers.
At The Harvard Crimson, one column suggests that there are some “visions of Zionism more morally objectionable” and therefore one might “feel wary of staying friends with Zionists.” It should then be no wonder to the author why Jewish students feel isolated on campuses.
This becomes all the more problematic when the students elected to represent the entire student union are not neutral nor representative on complex issues, particularly regarding the Israeli-Palestinian conflict at large.
At the University of Oxford, the Oxford Student Union elected Arwa Elrayess as the incoming president. She has been part of a no-budget documentary on the pro-Palestine protests that erupted after October 7. In one post promoting the film, Elrayess makes the moral equivalence between the Holocaust and the war against Hamas in Gaza by comparing the deaths of Anne Frank and Hind Rajab, a Gazan civilian.

Elrayess is meant to represent all students equally. Still, her posts suggest otherwise and are part of a worrying trend of using Jewish trauma to uncritically discuss Israel’s war.
As the current academic year continues, it remains clear that the issue of antisemitism on campus has not gone away, nor can it be afforded to be swept aside and ignored. When courses are built on debunked claims and student leaders use Holocaust inversion to further their anti-Israel narratives, it becomes evident that this issue is not isolated but rather is systemic, requiring urgent and sustained action.
Jewish students on campuses worldwide deserve the same safety and respect as any other student, and all students deserve an education grounded in truth and accuracy. The moral and intellectual integrity of higher education depends on confronting antisemitism directly, rather than allowing it to fester under the guise of activism or academic freedom.
