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.

Israel Court Extends Detention of Gaza Flotilla Activists

An Israeli court has extended by two days the detention of two activists arrested aboard a Gaza-bound flotilla that was intercepted by Israeli forces in international waters near Greece, their lawyer said on Sunday.
Saif Abu Keshek, a Spanish national, and Brazilian Thiago Avila were detained by Israeli authorities late on Wednesday and brought to Israel, while more than 100 other pro-Palestinian activists aboard the boats were taken to the Greek island of Crete.
A court spokesperson confirmed that their remand had been extended until May 5.
The governments of Spain and Brazil issued a joint statement on Friday calling their detention illegal.
The activists were part of a second Global Sumud flotilla, launched in an attempt to break Israel’s blockade of Gaza by delivering humanitarian assistance. The ships had set sail from Barcelona on April 12.
Israeli authorities requested a four-day extension of their arrest on suspicion of offenses that include assisting the enemy during wartime, contact with a foreign agent, membership in and providing services to a terrorist organization, and the transfer of property for a terrorist organization, said rights group Adalah, which is assisting in the activists’ defense.
Hadeel Abu Salih, the men’s attorney, said that the two deny the allegations. Their arrest was unlawful due to a lack of jurisdiction, she told Reuters at the Ashkelon Magistrate’s Court after the hearing, adding that the mission was meant to provide aid to civilians in Gaza, not to any militant group.
Abu Salih said that Abu Keshek and Avila were subjected to violence en route to Israel and kept handcuffed and blindfolded until Thursday morning.
Asked for comment, the Israeli military referred Reuters to the Israeli foreign ministry, which said that staff were compelled to act to stop what it described as violent physical obstruction by Abu Keshek and Avila. All measures taken were lawful, it said.

Israel Initiates Project to Counter Drone Threats in Sweeping Military Upgrade Plan

i24 News – Israel is moving forward with a new initiative to counter drone threats, as part of a broader strategy to expand military capabilities and reduce reliance on foreign defense suppliers, Prime Minister Benjamin Netanyahu said.
The drone project, ordered several weeks ago, is already in development, with officials preparing to review its initial progress. While details remain limited, the effort reflects growing concern over the increasing use of unmanned aerial systems in regional conflicts.
Netanyahu framed the initiative within a wider defense doctrine centered on “strengthening and independence,” emphasizing the need for Israel to maintain a decisive military edge. He noted that Israel is acquiring two squadrons of advanced fighter jets, including the F-35 Lightning II and the F-15IA, to reinforce its air superiority.
“These aircraft strengthen Israel’s overwhelming air superiority,” he said, referencing recent military operations as evidence of that advantage. He added that Israeli pilots are capable of operating at long range if necessary.
Alongside procurement, the government is planning a major expansion of domestic defense manufacturing. Netanyahu announced that Israel will allocate an additional 350 billion shekels ($95 billion) to the defense budget over the next decade, aiming to produce more of its own armaments and reduce dependence on foreign countries.
He also pointed to future ambitions to develop advanced aircraft domestically, describing the effort as potentially transformative for Israel’s defense industry.
The drone defense program, though still in early stages, is expected to become a key component of this strategy. Netanyahu acknowledged that the project will take time to fully develop but stressed that it is actively being pursued.
Despite the evolving nature of the threats, he reiterated Israel’s long-standing objective of maintaining military superiority across all domains.

Iran Presents US 3-Step Plan to Move from Ceasefire to End of War

i24 News – Iran has reportedly submitted a new draft agreement to the United States outlining a three-stage framework aimed at de-escalating regional tensions and restructuring oversight of its nuclear program, according to reporting from Al Jazeera.
The proposal was allegedly delivered via Pakistan and combines military, maritime, and nuclear commitments with a long-term regional security vision.
The first phase calls for transforming the current ceasefire into a permanent end to hostilities within 30 days, alongside a regional non-aggression pact that would include Iran’s allies and Israel. It also proposes steps such as gradually reopening the Strait of Hormuz, easing maritime restrictions on Iran, and reducing military activity in surrounding waters.
The second phase focuses on Iran’s nuclear program. It reportedly includes a freeze on uranium enrichment for up to 15 years, followed by a return to limited enrichment at 3.6%, in line with earlier international agreements.
The draft explicitly rejects dismantling Iran’s nuclear infrastructure. It also outlines possible arrangements for existing uranium stockpiles, including export or reprocessing, and calls for a structured sanctions relief mechanism tied to compliance milestones.
The final phase envisions broader regional engagement, with Tehran proposing a strategic dialogue between Iran and Arab states to establish a comprehensive security framework across the Middle East.
