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.

Canada Boosts Security at US, Israeli Diplomatic Buildings After Consulate Shooting

Canada is increasing security around US and Israeli diplomatic buildings after a shooting at the US consulate in Toronto, a Canadian police official said on Tuesday.
Royal Canadian Mounted Police Chief Superintendent Chris Leather said the consulate shooting is being investigated as a “national security incident,” although it’s too early to determine the motive.
Leather said the US and Israeli consulates in Toronto, the country’s most populous city, and embassies in the capital Ottawa will be seeing a change in the security posture in response to the shooting.
“These consulates deserve a heightened amount of vigilance and security at this time in the hopes that we can bring the temperature down in the coming days and weeks,” Leather told reporters at a press conference.
Toronto Police Deputy Chief Frank Barredo said police were called to the US consulate in Toronto around 5:30 am ET on Tuesday, where they found spent shell casings and damage to the building.
Barredo said witness evidence indicated that two men exited a white SUV that was stopped outside the consulate around 4:30 am ET, shot a handgun at the front of the building and then drove away.
While there were people in the building at the time of the shooting, police say no one was injured.
SYNAGOGUE SHOOTINGS
The consulate shooting follows three separate incidents last week where gunshots were fired at synagogues in the Toronto area. No one was injured in those shootings. Canadian Prime Minister Mark Carney called the attacks “criminal antisemitic assaults.”
Barredo said it’s too early to draw a connection between the consulate shooting and those at the synagogues.
“We definitely will be looking at any possible connections. Obviously, it is far too early in this investigation, but we do not look at them in isolation,” he said.
Canada‘s public safety minister described the consulate shooting as an unacceptable incident.
“The shooting … is absolutely unacceptable. Canada will never tolerate intimidation and violence of any kind, including towards our American friends in Canada,” Public Safety Minister Gary Anandasangaree said in a post on X.
The US State Department said in a statement that it was aware of the incident and was closely monitoring the situation in coordination with local law enforcement.
Separately, on Sunday, an improvised device exploded in Norway at the US embassy in Oslo, and police were still searching for a suspect, with a possible link to the Iran war among the lines of inquiry.
In New York City, two men have been charged with terrorism after throwing a homemade bomb at anti-Islam protesters over the weekend.

Suspected Hamas Member Detained in Cyprus Over Weapons Procurement

Cypriot authorities have detained a suspected member of Palestinian terrorist group Hamas wanted in Germany for procuring weapons and ammunition for attacks on Israeli or Jewish facilities, German federal prosecutors said on Tuesday.
The Lebanese-born suspect, identified only as Kamel M. in line with German privacy rules, was detained at Cyprus‘ Larnaca airport on March 6, arriving from Lebanon, they added in a statement.
The suspect is wanted in relation to the transport of 300 rounds of live ammunition, according to prosecutors. It wasn’t clear from the statement where the rounds had come from, or where they were thought to be heading.
“The operation served as preparation for deadly Hamas attacks on Israeli or Jewish institutions in Germany and Europe,” they said.
Police also searched the suspect’s apartment in Berlin.
Once Kamel M. is extradited to Germany, a judge will decide on pre-trial detention, the statement said.
Attacks against Jews and Jewish targets have risen worldwide since Israel’s war against Hamas in Gaza, triggered by the Islamist group’s 2023 attacks on Israel.

Russia Told Trump It Isn’t Sharing US Military Asset Info With Iran, Says Witkoff

Russia has denied sharing intelligence with Iran on US military assets in the Middle East, US special envoy Steve Witkoff said on Tuesday in a CNBC interview.
Witkoff said the denial came during a phone call that US President Donald Trump had with Russian President Vladimir Putin on Monday.
The Washington Post reported on Friday that Russia was providing Iran with targeting information that included locations of US warships and aircraft in the Middle East.
“Yesterday on the call with the president, the Russians said that they have not been sharing,” Witkoff said when asked if Washington thought Russia had shared with Tehran intelligence about the location of US military assets.
“We can take them at their word. But they did say that. And yesterday morning, independently, Jared [Kushner] and I had a call with [Kremlin foreign policy aide Yuri] Ushakov who reiterated the same,” said Witkoff.
He added: “That’s a better question for the intel people, but let’s hope that they’re not sharing.”
