Recalling an unsung Winnipeg-born hero of the Manhattan Project: Louis Slotin
Introduction: The recent release of the movie, “Oppenheimer” has generated a renewed interest in the effort that led to the development of the atomic bomb: “The Manhattan Project.”
Readers of The Jewish Post & News are likely aware of the important role that a Winnipegger played in that project: Louis Slotin. In 1995, our own frequent contributor, Martin Zeilig, wrote a lengthy article about Slotin for the historical magazine, “The Beaver.” Later that year, the former editor of this paper, the late Matt Bellan, also wrote a piece about Louis Slotin’s life and immensely tragic death, in which Matt drew from Martin’s article, also from another essay that had been sent to this paper.
Here is Matt Bellan’s article about Louis Slotin, from the August 16, 1995 Jewish Post & News”
In the past few weeks, the media have presented a flood of stories tying in with the 50th anniversary of the explosion of atomic bombs over Hiroshima and Nagasaki.
For Winnipeg Jews, it’s also timely to commemorate the passing of a member of this community involved in the development of the first American A-bombs.
Louis Slotin sacrificed his life to save colleagues in 1946, while doing further research on the A-bomb at Los Alamos, New Mexico.
Two essays that arrived at The Jewish Post & News this month shed light on Slotin’s heroics and his life. Bernice Faintuch of Skokie, Illinois sent in “Tickling the Dragon’s Tail: A True Story”, a chapter in a book titled Time Bomb: Understanding the Threat of Nuclear Power, by Browne and Munroe, published by William Morrow and Company.
And Beth Slotin Shore, a niece of Lou is Slotin ‘s, forwarded an essay by Martin Zeilig that appears in the August/September issue of The Beaver, titled “Dr. Louis Slotin and ‘The Invisible Killer’’’.
Born here in 1910 to Yiddish-speaking immigrants Israel and Sonia Slotin, Louis Slotin grew up in the North End, attended Machray School and St. John’s Tech, and showed his brilliance at an early age. He specialized in science at the University of Manitoba, winning the gold medal in science and physics. After receiving his Masters Degree at the U of M, Slotin went on to study at King’s College in London, England, on a fellowship, and received a doctorate in biochemistry from London University in 1936.
In 1937, he was appointed a nuclear research associate at the University of Chicago, and over the next few years, did extensive pioneering research into the effects of radiation on cancer.
Slotin was recruited to work for the U.S. government’s A-Bomb Program, the Manhattan Project, in Los Alamos, New Mexico. He arrived there in 1944, and soon became a master of the dangerous science of assembling the critical firing mechanism for the atomic bomb.
In 1946, Slotin continued doing research on the bomb, as part of the U.S.’s effort to maintain military superiority over the Soviet Union. “His responsibility was to determine how much enriched uranium had to go into the core of the bomb to make sure there was a chain reaction,” Israel Ludwig, Slotin’s nephew, told The Jewish Post & News last week. Ludwig, who’s visited the Los Alamos site, notes that enriched uranium was scarce at the time, and guesses part of Slotin’s job was to see how little could be used to make an effective bomb.
In an experiment that year. the 34-year-old researcher was moving two hemispheres filled with plutonium together, a micro-inch at a time, to see how close he could move them to cause a chain reaction. A screwdriver he was holding to keep the hemispheres from touching accidentally slipped, and a chain reaction started, filling the room with deadly radiation.
Slotin quickly pried the hemispheres apart to stop the reaction. “He did more than pull the spheres apart,” adds Ludwig, who talked to a scientific witness to the event. “He threw himself on the experiment.”
Over the next nine days, the young Winnipegger died an agonizingly painful death from radiation sickness. Nearly 3,000 people showed up at his family’s Scotia Street home for the funeral, and heard Rabbi Louis S. Frank describe Slotin as “one of the most brilliant scholars ever to come out of this city,” Zeilig writes.
He was buried at Shaarey Zedek Cemetery, notes Beth Shore. Last year, at the initiative of Jewish Winnipegger Lawrence Lavitt, the city created a new park in Slotin’s name at Polson Avenue and Scotia Street, about half a block from his Scotia Street home.
Slotin’s tragic death was even more galling because he was planning to leave nuclear weapons research, and do further work on using radiation to kill cancer cells. How bitterly ironic it is that he died from an overdose of radiation, instead.

Will the Democratic Socialists of America control the Democratic Party?
By HENRY SREBRNIK On June 23, radical Democratic Socialists of America (DSA) candidates backed by New York mayor Zohran Mamdani won multiple Democratic Party primaries in New York City and elsewhere in the state. They also were victorious in other parts of the country.
The socialist victories in New York far surpassed anyone’s predictions. Who, three years ago, could have predicted that a Muslim anti-Zionist would be elected mayor of a city with 900,000 Jews and would lead insurgents to victories in that party’s primaries in 2026? Yet here we are.
Marxist Third Worldist ideology has moved out of the universities into the polling booths, after campus activism, divestment campaigns, and social media have reinforced an anti-Israeli framework for years. The DSA’s platform states it plainly: It pledges “support for Palestinian self-determination against Israeli apartheid and settler-colonialism.”
The mayor, a long-standing DSA member, worked overtime to appear at countless campaign events for a trio of candidates he dubbed “the Team”: Claire Valdez, Darializa Avila Chevalier, and Brad Lander. The last two unseated incumbent Democratic congressmen. Mamdani has assembled a coalition in New York City that is capable of elevating like-minded candidates to office.
In the Seventh Congressional District, which straddles northern Brooklyn and southwestern Queens, an open primary to replace retiring progressive Rep. Nydia Velázquez saw State Assembly Member Claire Valdez’s’s defeat Brooklyn Borough President Antonio Reynoso. She was even further left than Mamdani himself. In the end, it was not even close: Valdez prevailed with 56.1 per cent of the vote to Reynoso’s 35.8 per cent.
In 2019, Valdez joined the DSA after seeing the rise of Rep. Alexandria Ocasio-Cortez and state senator Julia Salazar, both of whom were elected with the DSA’s help. Valdez emphasized her anti-Israel activism as a key part of her campaign. At events, her staff handed out signs that said “Free Palestine.” She launched her campaign alongside Mahmoud Khalil, a key anti-Israel leader at Columbia University that the Donald Trump administration has tried to deport.
Valdez referred to Israel’s war against Hamas as a “genocide” as early as October 13, 2023. She lambasted police for restraining anti-Israel mobs chanting “Globalize the Intifada” and waving Hezbollah flags outside a Brooklyn synagogue last June. “New Yorkers don’t just have the right to protest the sale of stolen Palestinian land — they have a responsibility to,” she declare. She has repeatedly criticized the American Israel Public Affairs Committee (AIPAC). She also boasted on social media of having “wiped my hand on the American flag.”
In the Thirteenth Congressional District, covering the upper Manhattan neighborhoods of Harlem, Washington Heights, and Morningside Heights and parts of the West Bronx, Darializa Avila Chevalier won a much more startling victory over Rep. Adriano Espaillat, a five-term incumbent Democratic Party power broker and chair of the Congressional Hispanic Caucus. Espaillat’s campaign was heavily backed by AIPAC. Chevalier defied expectations and won by gaining 49 per cent to Espaillat’s 46 per cent. She told the crowd at her watch party that she had fought against the “Democratic machine.” Espaillat lost despite the backing of Democratic leaders in Congress and the state, including House Minority Leader Hakeem Jeffries, New York Governor Kathy Hochul, and Julie Menin, speaker of the New York City Council.
When Chevalier, draped in a keffiyeh, first announced her candidacy in November of last year, few outside her immediate circle knew her name. But her message was clear: she presented herself as an organiser working to unite families torn apart by the immigration system and against “what we all know is a genocide in Palestine.”
Chevalier has publicly proclaimed her hatred for Israel, the United States, and “Western civilization” as a whole. She has called for the abolition of prisons, open borders and an end to deportations — even for people convicted of violent crimes. As a student at Columbia University, she was involved in Students for Justice in Palestine. In 2024, she returned to her alma mater to help organize an anti-Israel encampment that was ultimately disbanded by the police.
She co-founded Columbia University Apartheid Divest: “We are Westerners fighting for the eradication of Western Civilization. We stand in full solidarity with every movement for liberation in the Global South. Our intifada is an Internationalist one,” it states.
The day after the October 7 attack, Chevalier attended an anti-Israel demonstration in Times Square. “I can only say I have been advocating for the human rights of Palestinians for my adult life,” when asked about her attendance at the rally. Chevalier has said that her conversion to Islam was inspired by the Israel-Hamas war. Mamdani celebrated her win, describing Chevalier as a person “of clarity, of conscience and of conviction.”
The war was also on the minds of voters in former Comptroller Brad Lander’s race against another AIPAC-funded incumbent, Rep. Dan Goldman, in New York’s Tenth District, covering lower Manhattan and part of Brooklyn. Both are Jewish, but Goldman has been a steadfast friend of Israel while Lander is the quintessential anti-Zionist and a key faction of his coalition was anti-Israel. It was a contest that laid bare the party’s divisions over the Israel-Gaza war.
At his son Marek’s bris, Lander gave a speech lambasting Israel. “We pray fervently that by the time you read this, the Israeli occupation of the West Bank and Gaza, the settlements, the house demolitions, the violence will be history,” which was later reprinted in a 2003 book titled Wrestling with Zion. Lander enjoyed the night’s biggest victory, winning 65.8 per cent of the vote to Goldman’s 34 per cent. Many Democrats have suggested that Lander has proved useful to Mamdani and other leftists who have been accused of antisemitism for singling out the Jewish state for opprobrium.
In the run-up to Election Day, a chain of Brooklyn coffee shops called Poetica posted that it would have barred Goldman entry had they recognized him during a recent visit to their storefront. “We don’t serve racists, fascists, homophobes, genocide enablers,” Poetica declared. “Too bad we didn’t recognize you right away, or we would have turned you away.”
At the state level, seven of the eight candidates endorsed by the DSA for the New York State legislature also won their primary elections. One of them is Aber Kawas, a Queens-based community organizer. If she, as expected, wins in November, she will be the first Palestinian woman elected to state office in New York history.
“Were defeated congressmen Dan Goldman and Adriano Espaillat insufficiently anti-Trump?” asked Will Rahn, a senior editor and writer for The Free Press, rhetorically, in a June 26 column. “Of course not. They lost because they aren’t anti-Israel enough. ‘Free Palestine’ is now the binding issue on the left, the only thing that actually matters.” No matter who you are, how you identify, or what causes you’ve championed, if you refuse to fall in line on Israel, you risk being ostracized from communities you’ve long called home.
For most of the postwar era, support for Israel was one of the least controversial positions in Democratic Party politics. That consensus has not merely weakened; it has collapsed. Once viewed as a righteous anti-colonial cause, Zionism has been reframed by radical thinkers as the ideology of a colonial oppressor of stateless Palestinians. Opposition to Israel is now the litmus test in Democratic Party politics. “There’s a cliff, and we’re heading towards it,” warned Daniel C. Kurtzer, a Princeton University professor who was ambassador to Israel under President George W. Bush.
The DSA has now built an entire ecosystem that runs parallel to the official Democratic apparatus, equipped with their own consultant network, endorsing organizations, donors and even billionaires who back them.
A generation after Pat Buchanan was denounced as an antisemite by all proper liberals for saying things like “Capitol Hill is Israeli-occupied territory,” will the left now embrace him as a “premature antizionist”? Even satire can’t match this.
Think about it: Since October 7, Israel has done what every other country viciously attacked by implacable enemies throughout history has done: It has lashed back in a defensive war. This is a policy that any state that cared for the life of its citizens would have to adopt.
Yet Israel has become the “omnicause.” That’s why antisemitism and antizionism are two sides of the same coin: hatred of Jews. Jews around the world aren’t being attacked because of Israel. Israel is itself being condemned because it’s Jewish.
American Jews have been blindsided by this, as the French writer Simone Rodan-Benzaquen, senior envoy for Europe at the Foundation for Defense of Democracies, tells us in a brilliant article, “Stand Up,” Tablet, July 6, 2026. “When anti-Jewish hostility arrives wrapped in the language of liberation, antiracism, decolonization, and human rights –when it emerges among allies, colleagues, students, professional peers, or other minority communities — the disorientation is deeper. It is inside the world in which one has built a life. It speaks in familiar accents. It borrows cherished values.”
In “A Profound Question Haunting Jews Today,” New York Times, July 6, 2026, Nicholas Lemann, the former dean of the Columbia University Journalism School, agrees. He writes that for half a century or more, American Jews could achieve, “through being successful, culturally Jewish, Zionist, liberal and not especially observant,” a status that elsewhere has persistently eluded them.
“This set of certainties has evaporated. Today, Israel is the pariah nation of the world, and ‘Zionist’ has become an epithet, something it’s unacceptable to be, at least in progressive circles,” where most Jews have usually found themselves.
So, are the Democrats going to become America’s anti-Israel party? And then what?

Discover Your Ultimate Smooth at Sets on Corydon: Nanoplasty vs. Keratin vs. Japanese Straightening
Are you ready to wake up with flawless, effortless hair every single day? While standard straightening methods try to fit everyone into the same box, your hair has its own unique structure, strength, and history.
We offer three distinct, state-of-the-art smoothing and straightening systems. Finding the perfect match depends entirely on your hair type, your lifestyle, and your ultimate hair goals.
Here is exactly how they compare so you can choose the path to your most beautiful, resilient hair.
The Treatment Breakdown
1. The Elite Standard: Nanoplasty (Our Premier Selection)
Nanoplasty is a revolutionary, high-technical smoothing treatment that works at a deep cellular level. Using nanotechnology, nutrients and amino acids are deeply integrated right into the hair cortex (the inner core of the hair strand). It heals, seals, and straightens from the inside out without harsh chemicals.
- How it works: It uses an acidic formula triggered by specialized infrared heat to realign the hair bonds. It does not just coat the cuticle; it restructures it while infusing massive hydration.
- The Finish: Ultra-glossy, high-shine, sleek, and straight, while retaining natural movement and zero frizz.
- The Big Benefit: Formulated without formaldehyde or harsh chemicals. There are no fumes, no burning eyes, and you can wash your hair or tie it up the very same day.
- Longevity: Lasts up to 4 to 6 months.
2. The Classic De-Frizzer: Keratin Treatment
The traditional choice for managing unruly texture. Keratin acts like a protective shield, filling in the cracks along a compromised or distressed hair cuticle (the protective outer layer).
- How it works: A liquid keratin formula is sealed into the outer layer of the hair with a flat iron.
- The Finish: Soft, smooth, and incredibly manageable. It reduces curl volume by roughly 50 to 70% and completely deletes frizz, but leaves some of your natural body and bounce.
- The Big Benefit: Ideal for hair that has undergone chemical stress or bleaching. It acts like a temporary protein bandage to restore softness and cut your blow-dry time in half.
- Longevity: Lasts 3 to 4 months, gradually washing out over time.
3. The Permanent Sleek: Japanese Straightening (Thermal Reconditioning)
For those who want absolute, pin-straight hair that defies high humidity and never reverts.
- How it works: This is a permanent chemical process that physically breaks down the internal bonds of the hair, which are then precision-ironed perfectly flat and neutralized to lock in the new shape forever.
- The Finish: Mirror-smooth, pin-straight, glassy hair with zero wave or curl.
- The Big Benefit: It is completely permanent on the hair that is treated. Rain, humidity, and workouts will not change it. Only your new root growth will need touching up.
- Longevity: Permanent (requires root touch-ups every 6 to 9 months).
Which One Is Right For You?
| Feature | Nanoplasty | Keratin Treatment | Japanese Straightening |
| Primary Goal | Deep cellular repair, sleek straightening, intense gloss. | Frizz elimination, volume reduction, softer texture. | Permanent, absolute pin-straight results. |
| Hair Condition | Healthy to moderately sensitized or colored hair. | Highly compromised, bleached, or heat-distressed hair. | Healthy, resistant, coarse, or virgin hair only. |
| Chemical Type | Amino acids & organic acids (No formaldehyde fumes). | Cuticle-coating formulas (May contain standard preservatives). | Traditional alkaline straightening solution. |
| Post-Care Window | Wash or style immediately. No waiting period. | Must wait 48 to 72 hours before washing or tying up. | Must keep completely dry and straight for 48 to 72 hours. |
An Important Note on Hair Integrity: Beautiful hair is healthy hair. Because Japanese Straightening permanently alters the internal architecture of the hair strand, it is completely unsuitable for heavily highlighted, bleached, or fragile hair. If your hair has a history of heavy chemical processing, a customized Nanoplasty or Keratin Treatment will give you the breathtaking, smooth results you want while respecting and preserving the strength of your hair structure.
