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.

i24 News – The United States and Israel are engaged in intense preparations — the largest since the cease-fire took effect — for the possible resumption of attacks against Iran as early as next week, the New York Times reported Saturday citing two Middle East officials, who spoke on condition of anonymity.
Meanwhile, the Israeli Mako News reported Israeli official sources as saying that US President Donald Trump is expected to convene his closest team of advisors in the next 24 hours to make a final decision on the Iran matter. Israel estimates that a decision on military action may be made very soon, the report added.
According to NYT, should Trump decide to resume military strikes, options include more aggressive raids targeting Iranian military and infrastructure targets, US officials said.

Trump Says Xi Agrees Iran Must Open Strait, But No Sign China Will Weigh In

US President Donald Trump said Chinese President Xi Jinping had agreed Tehran must reopen the Strait of Hormuz, though China gave no indication it would weigh in.
Flying back from Beijing on Friday after two days of talks with Xi, Trump said he was considering whether to lift US sanctions on Chinese oil companies buying Iranian oil. China is the biggest buyer of Iranian oil.
“I’m not asking for any favors because when you ask for favors, you have to do favors in return,” Trump said when asked by a reporter on Air Force One whether Xi had made a firm commitment to put pressure on the Iranians to reopen the strait.
Xi did not comment on his discussions with Trump about Iran, although China’s foreign ministry criticized the war, calling it a conflict “which should never have happened, has no reason to continue.”
‘WE WANT THE STRAITS OPEN’
Iran has effectively shut the strait, which carried one-fifth of global oil and liquefied natural gas supply before the US and Israel launched attacks on February 28. The disruption to shipping has caused the biggest oil supply crisis in history, pushing up oil prices.
Ebrahim Azizi, who heads the Iranian parliament’s national security committee, said on Saturday that Tehran had prepared a mechanism to manage traffic through the strait along a designated route that would be unveiled soon.
Azizi said only commercial vessels and parties cooperating with Iran would benefit, and that fees would be collected for specialized services provided under the mechanism.
Thousands of Iranians were killed in the US and Israeli airstrikes. Thousands more have been killed in Lebanon in fighting between Israel and the Iran-backed group Hezbollah, though Israel and Lebanon agreed on Friday to a 45-day extension of a ceasefire that has tamped down the conflict there.
The US paused its attacks last month but began a port blockade. As of Saturday, 78 commercial ships had been redirected and four disabled to ensure compliance with the blockade, the US military said.
Tehran, which carried out strikes against Israel, US bases and Gulf states after the war began, has said it will not unblock the strait until the US ends its blockade. Trump has threatened to resume attacks if Iran does not agree to a deal.
“We don’t want them to have a nuclear weapon, we want the straits open,” Trump said in Beijing, alongside Xi.
Iran, which has long denied it intends to build a nuclear weapon, has refused to end nuclear research or relinquish its hidden stockpile of enriched uranium.
Iranian Foreign Minister Abbas Araqchi said Tehran had received messages from the US indicating Washington was willing to continue talks.
Pakistan has been mediating between Washington and Tehran. Iranian news agency Nournews said Interior Minister Eskandar Momeni had held “detailed” discussions with his visiting Pakistani counterpart on Iran-Pakistan relations and the prospects for resuming peace talks, but gave no details.
TRUMP LOSING PATIENCE
Trump, who told Fox News’ “Hannity” program in an interview aired on Thursday that he was losing patience with Iran, said Tehran “should make a deal.”
Oil prices rose around 3 percent to around $109 a barrel on Friday [O/R] on concerns about a lack of progress in resolving the conflict.
Talks on ending the war, which has become a liability for Trump ahead of US congressional elections in November, have been on hold since last week when Iran and the US each rejected the other’s most recent proposals.
Araqchi said on Friday that Iran would welcome Chinese input, adding that Tehran was trying to give diplomacy a chance but did not trust the US, which has curtailed previous rounds of talks by launching air strikes.
When the US and Israel launched their attacks on Iran at the end of February, they said one of their aims was to weaken the authorities so Iranians could topple the government.
There has been little sign of organized dissent in Iran during the war, and rights groups say the government has cracked down heavily on its opponents.
Iran’s judiciary said on Saturday that 39 people had been executed for collaborating with Israeli or US spy agencies, or taking part in “terror” or armed unrest, since the war started, the judiciary’s news agency Mizan reported.
It said 36 “medium-level” dissidents had received long prison sentences.

Tens of Thousands March in London in Separate Immigration, Pro‑Palestinian Protests

Tens of thousands of people marched through central London on Saturday in two separate protests – one against high levels of immigration and another in support of Palestinians.
Police deployed 4,000 officers, including reinforcements from outside the capital, and pledged “the most assertive possible use of our powers” in what they called their biggest public order operation in years.
By 1200 GMT, shortly after both marches started, police said they had made 11 arrests for a range of offenses. They had earlier forecast turnout of at least 80,000.
Prime Minister Keir Starmer on Friday accused organizers of the Unite the Kingdom march of “peddling hate and division, plain and simple.”
The march was organized by anti-Islam activist Stephen Yaxley-Lennon, known as Tommy Robinson. The government barred 11 people it described as “foreign far-right agitators” from entering Britain to address the protest.
A previous protest led by Robinson in September drew around 150,000 people, police said, and featured a video address by US tech billionaire Elon Musk. More than 20 people were arrested, and police are still seeking more than 50 suspects.
MARCHERS WAVE BRITISH AND ENGLISH FLAGS
On Saturday, Robinson supporters gathered in central London, waving mainly British and English flags.
“I think that too much migration – not migration, but too much migration – is causing a lot of problems, upsetting a delicate balance here,” said Allison Parr, who also criticized net-zero environmental policies.
Annual net migration approached 900,000 in 2022 and 2023, but fell back to around 200,000 last year after tighter work visa rules.
Concern over immigration – including the arrival of asylum seekers on small boats – has weighed on Starmer’s popularity and boosted the right-wing Reform UK party, whose leader Nigel Farage has distanced himself from Robinson.
Some protesters chanted abuse about Starmer.
Robinson, who has convictions for assault, stalking and other offenses, urged supporters this week to act peacefully in what he billed as “the greatest patriotic display the world has ever seen.”
Earlier this year, he traveled to the US, where he met a State Department official and addressed supporters about what he called “the dangers of Islam” and “the Islamification of Great Britain.”
Census data showed 6.5 percent of people in England and Wales identified as Muslim in 2021, up from 4.9 percent in 2011.
PRO-PALESTINIAN PROTESTERS MARK NAKBA DAY
Nearby, pro-Palestinian demonstrators held a march to mark Nakba Day, commemorating Palestinians’ loss of land in the 1948 war that followed the creation of Israel. “Nakba” means catastrophe in Arabic.
The march also drew those opposing the Unite the Kingdom rally, alongside predominantly Palestinian flags.
London has recently seen a spate of arson attacks on Jewish sites, and two Jewish men were stabbed last month in an incident being treated as terrorism.
Police said repeated large pro-Palestinian marches – 33 since the Hamas-led attack on Israel in October 2023 – had left many Jewish people feeling too intimidated to enter central London.
While protesters held a range of views, police said they routinely made arrests for racially and religiously aggravated public order offenses, inciting racial hatred or supporting proscribed organizations.
The government said police would arrest protesters who chanted “globalize the intifada,” a reference to Palestinian uprisings against Israel that many British Jews view as inciting antisemitism.
Some protesters on Saturday chanted “Death to the IDF”, referring to the Israeli army – language that police said had previously been a reason for arrests when aimed at Jewish people.
