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.

US Strikes More Than 90 Iranian Military Targets on Kharg Island, CENTCOM Says

United States forces executed a large-scale precision strike on Kharg Island in Iran on Friday night, the US Central Command said on Saturday.
“US forces successfully struck more than 90 Iranian military targets on Kharg Island, while preserving the oil infrastructure,” CENTCOM said.
The strike destroyed naval mine storage facilities, missile storage bunkers, and multiple other military sites, the US military said in a post on X.
President Donald Trump threatened on Friday to strike the oil infrastructure of Iran’s Kharg Island hub, unless Tehran stopped attacking vessels in the Strait of Hormuz.

North Korea Fires Ten Ballistic Missiles Toward the Sea of Japan

i24 News – North Korea fired roughly ten ballistic missiles toward the Sea of Japan on Saturday, the South Korean military reported, marking a new act of defiance amid Seoul and Washington’s annual joint military exercises.
The launches, originating from the Sunan area near Pyongyang, were detected around 1:20 p.m. local time, according to a statement from the South Korean Joint Chiefs of Staff.
The missiles were directed toward the East Sea—the Korean name for the Sea of Japan—though details on their range or trajectory were not immediately available. Earlier, the South Korean Ministry of Defense had already confirmed the launch of at least one unidentified projectile in the same area.
The Japanese Ministry of Defense also verified the incident, noting that a suspected ballistic missile had been launched from North Korea.
The launches come amid rising tensions on the Korean Peninsula. Since Monday, the United States and South Korea have been conducting their annual joint exercises, which will continue through March 19 and involve approximately 18,000 South Korean troops alongside an unspecified number of U.S. forces.
Pyongyang has sharply criticized the drills, calling them a rehearsal for invasion. Kim Yo Jong, the influential sister of North Korean leader Kim Jong-un, warned this week that the exercises could trigger “terrible and unimaginable consequences.”
The missile tests also coincide with fading prospects for inter-Korean dialogue. Kim Jong-un recently dismissed outreach efforts from South Korean President Lee Jae Myung, labeling Seoul “the most hostile enemy.”
The show of force occurred just hours after South Korean Prime Minister Kim Min-seok, during a visit to the United States, mentioned a potential meeting between U.S. President Donald Trump and Kim Jong-un—a meeting Washington still considers possible.

Dutch Authorities Investigate Explosion at Jewish School Claimed by Extremist Group

i24 News – An explosion struck a Jewish school on Zeelandstraat in Amsterdam-Buitenveldert during the night between Friday and Saturday, Dutch authorities confirmed. Emergency responders, including police and firefighters, acted swiftly, and officials reported that the building suffered only limited damage. No injuries have been reported.
Mayor Femke Halsema described the incident as a deliberate attack against the Jewish community in the city, emphasizing that the authorities are treating the case “very seriously.” Security camera footage showing the individual who detonated the device is under investigation.
In an unverified online video, previously little-known group identifying itself as Ashab Al Yamim later claimed responsibility for the blast. The group released online footage appearing to show the small explosion followed by a fire outside the school. Its logo was also seen in videos related to an attack on a synagogue in Rotterdam earlier this week.
Dutch investigators are coordinating with the judiciary to determine the full circumstances of the attack and whether additional suspects were involved. Authorities noted that the organization had not been previously known to security services.
The explosion comes amid rising security concerns for Jewish institutions across Europe, following heightened tensions in the Middle East. The group behind the claim has also alleged responsibility for previous incidents targeting Jewish sites in Europe, including attacks in Liège, Belgium, and Rotterdam, though these claims remain unverified.
Jewish schools, synagogues, and community centers across the continent have stepped up security measures in recent weeks amid fears of potential threats to Jewish communities.
