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.

Downed Planes Raise New Perils for Trump as Tehran Hunts for Missing US Pilot

Two US warplanes were downed over Iran and the Gulf, Iranian and US officials said on Friday, with two pilots rescued and a third still missing and being hunted by Tehran’s forces.
The incidents show the risks still faced by US and Israeli aircraft over Iran despite assertions from US President Donald Trump and his Defense Secretary Pete Hegseth that their forces had total control of the skies.
The first plane, a two-seat US F-15E jet, was shot down by Iranian fire, officials in both countries said.
The second plane, an A-10 Warthog fighter aircraft, was hit by Iranian fire and crashed over Kuwait, with the pilot ejecting, two US officials said.
Two Blackhawk helicopters involved in the search effort for the missing pilot were hit by Iranian fire but made it out of Iranian airspace, the two US officials told Reuters.
The degree of injuries among the crew of the aircraft remained unclear. The status and whereabouts of the missing F-15E crew member was not publicly known.
Iran’s Revolutionary Guard Corps said it was combing an area near where the pilot’s plane came down in southwestern Iran and the regional governor promised a commendation for anyone who captured or killed “forces of the hostile enemy.”
Iranians, who have been pummeled by American air power for weeks, posted gleeful messages celebrating the plane downings. Iran’s Parliament Speaker Mohammad Baqer Qalibaf said on X that the U.S. and Israel’s war had been “downgraded from regime change” to a hunt for their pilots.
Trump has been in the White House receiving updates on the search-and-rescue operation, a senior administration official told Reuters. The Pentagon and US Central Command did not immediately respond to requests for comment.
NO SIGN OF END TO WAR
The prospect of a US service person being alive and on the run inside Iran raises the stakes for Washington in a conflict with low public support and no sign of an imminent end.
Iran has officially told mediators it is not prepared to meet with US officials in Islamabad in coming days and that efforts to produce a ceasefire, led by Pakistan, have reached a dead end, the Wall Street Journal reported on Friday.
The US and Israel opened the campaign with a wave of strikes that killed Iran’s Supreme Leader Ayatollah Ali Khamenei on February 28. The war has killed thousands and threatened lasting damage to the global economy.
So far, 13 US military service members have been killed in the conflict and more than 300 have been wounded, according to the US Central Command.
Iran has rained down drones and missiles on Israel. It has also taken aim at Gulf countries allied to the US, which have so far held back from joining the war directly for fear of further escalation.
In a security alert on Friday, the US embassy in Beirut said Iran and its aligned armed groups may target universities in Lebanon and urged US citizens in the country to leave while commercial flights are still available.
Israel has been waging a parallel campaign against Iran-backed Hezbollah in Lebanon after the militant group fired at Israel in support of Iran.
TRUMP THREAT TO STRIKE BRIDGES, POWER PLANTS
On Friday, as Trump threatened to hit its bridges and power plants, Iran struck a power and water plant in Kuwait, underlining the vulnerability of Gulf states that rely heavily on desalination plants for drinking water.
On Thursday, Trump posted footage on social media showing dust and smoke billowing up as US strikes hit the newly constructed B1 bridge between Tehran and nearby Karaj, which was due to open this year, and said more attacks would follow.
“Our Military, the greatest and most powerful (by far!) anywhere in the World, hasn’t even started destroying what’s left in Iran. Bridges next, then Electric Power Plants!” he wrote in a subsequent post.
On Friday, a drone hit a Red Crescent relief warehouse in the Choghadak area of Iran’s southern Bushehr province.
Kuwait Petroleum Corporation said its Mina al-Ahmadi refinery had been hit by drones. Other attacks were also reported to have been intercepted in Saudi Arabia and Abu Dhabi. Missile debris landed near the Israeli port of Haifa, site of a major oil refinery.
Oil markets were closed after benchmark U.S. crude prices gained 11% on Thursday following a speech by Trump that offered no clear sign of an imminent end to the war.

US-Iran: Diplomatic Push Falters as Qatar Steps Back and Pakistan Talks Stall

i24 News – Diplomatic efforts to secure a ceasefire between Washington and Tehran appear to have reached an impasse, as key regional mediators pull back and broader talks stall.
According to reporting by The Wall Street Journal, Qatar has informed US officials that it does not wish to take a central role in mediating between the two sides. Officials familiar with the matter said Doha has made clear it is “not willing” to lead negotiations or act as the primary broker.
At the same time, Pakistan-led efforts to bring Iranian and American officials together have also stalled. Mediators say Tehran has refused to attend proposed meetings in Islamabad, calling Washington’s conditions “unacceptable,” further underscoring the widening gap between the two sides and the growing difficulty of restarting dialogue.
Despite the deadlock, diplomatic channels have not fully closed. Turkey and Egypt are continuing parallel efforts to revive talks, with discussions underway about potential alternative venues, including Doha and Istanbul.
US President Donald Trump downplayed the impact of recent military developments on diplomacy, including the destruction of a US fighter jet during operations in Iran. Speaking in a brief exchange with an NBC News journalist, he said: “No, not at all. It’s war. We are at war.”
He further fueled speculation with a cryptic social media post on Truth Social, writing: “Keep the oil, anyone?” criticising international allies on Friday over rising fuel prices. Trump appeared to mock allies such as the United Kingdom, writing that they should “keep the oil.”

Report: Iran Retains Significant Missile Capability Despite Weeks of US-Led Strikes

i24 News – Despite weeks of sustained airstrikes by the United States and its allies, Iran has reportedly managed to retain a substantial portion of its military capabilities, particularly its ballistic missile arsenal.
According to a report by The New York Times citing US intelligence assessments, Tehran has developed methods to mitigate the impact of the strikes, allowing it to preserve and restore key parts of its missile infrastructure.
While the Pentagon has claimed responsibility for striking more than 11,000 targets over five weeks and reducing the rate of Iranian missile fire, intelligence officials now caution that the actual damage may be more limited than initially assessed. Iranian forces are reportedly able to rapidly repair or reactivate missile launchers stored in heavily fortified or underground facilities, sometimes within hours of being hit.
Analysts also point to the widespread use of decoy sites, which may have drawn strikes away from operational assets. Many of the targeted locations are believed to have contained dummy installations, complicating efforts to accurately gauge the degradation of Iran’s ballistic capabilities. Combined with deep underground bunkers and dispersed storage networks, this approach is seen as enabling Tehran to maintain a higher level of readiness than publicly estimated.
US intelligence officials assess that this resilience reflects a deliberate strategy: preserving a credible long-range strike capability as both a deterrent and a bargaining tool in any future negotiations, while ensuring regime survival and continued regional influence.
Despite sustained air dominance claimed by Washington and its allies, Iran’s adaptive tactics continue to complicate battlefield assessments, leaving the true balance of power in the conflict uncertain.
