Famous Orthodox Jews You Might Not Know About

I teach in a girls' school, and every year I play a little game with my students on the first day. I show them photos of famous people and ask if they can guess which ones are Orthodox Jews. Every year, the same reaction — genuine shock. "Wait, HE keeps Shabbos?" Yes. "SHE is frum?" Yes. "But he's a BILLIONAIRE." As if billionaires can't bench after a meal.

This reaction fascinates me, because it reveals something we don't talk about enough: Orthodox Jews are out there in every field imaginable, navigating board meetings and courtrooms and laboratories and film sets, and doing it all while keeping Shabbat, eating only kosher food, and davening three times a day. Their stories aren't just interesting — they're proof that living by Torah values and thriving in the modern world aren't contradictions.

Let me tell you about some of them. Not as a Wikipedia list, but as stories — because that's what they are.

The Reichmanns: Skyscrapers That Rested on Shabbos

The Reichmann family of Toronto built Olympia & York into the largest real estate development company in the world. They developed the World Financial Center in New York and Canary Wharf in London — one of the most ambitious construction projects in European history. We're talking billions of dollars, thousands of workers, enormous political and financial pressure.

And every Friday afternoon, the cranes went silent.

I want you to sit with that for a second. In the middle of building Canary Wharf — a project so massive it reshaped London's skyline — Paul Reichmann shut down construction every Friday before Shabbat. The non-Jewish construction workers would later say they'd never seen anything like it. The entire site would go quiet. No exceptions. No "just finish this one pour of concrete." Silent.

The financial cost of stopping a megaproject for 25 hours every week was staggering. Competitors didn't have that constraint. Investors raised eyebrows. But the Reichmanns were clear: Shabbos is Shabbos. The buildings could wait. The cranes would be there Sunday morning.

The Reichmanns eventually faced financial difficulties in the early 1990s, but their legacy goes far beyond the buildings. They showed the world that you could operate at the highest levels of global business without compromising an inch on religious observance. My students always love this story. The idea that someone would walk away from a billion-dollar construction site because the sun was setting on a Friday — it makes the concept of Shabbat feel powerful instead of restrictive.

Rabbi Jonathan Sacks: The Rabbi Who Spoke to the World

Rabbi Jonathan Sacks, who passed away in 2020, was the kind of person who could make a room full of skeptics sit up and listen. As the Chief Rabbi of the United Kingdom, he didn't just lead the British Jewish community — he became one of the most important moral voices of his generation, period.

He wrote over thirty books. He was knighted by the Queen. He addressed the House of Lords, the European Parliament, and the United Nations. His TED Talks have millions of views. And he did it all as a man who wore a kippah, kept Shabbat, learned Torah daily, and was unapologetically Orthodox.

What made Rabbi Sacks special wasn't just his intellect — though his mind was extraordinary. It was his ability to take deep Torah ideas and make them relevant to everyone. His book "The Dignity of Difference" argued for religious pluralism using the language of both Torah and Western philosophy. He could quote the Rambam and John Stuart Mill in the same paragraph and make both feel essential.

I keep a copy of his book "Morality" on my nightstand. Every time I feel discouraged about the state of the world, I read a chapter. His voice — warm, wise, deeply rooted — reminds me that Torah has something to say to every generation. When he passed away, people of every faith mourned. That tells you something about the man.

Shlomo Yehuda Rechnitz: The Billionaire Who Crashed a Wedding

Here's a story that still makes me cry when I tell it.

Shlomo Yehuda Rechnitz is a Los Angeles businessman worth over a billion dollars. He built a healthcare empire — nursing homes and long-term care facilities. He's also one of the most extraordinary baalei tzedakah (philanthropists) in the Orthodox world, giving away tens of millions of dollars to yeshivos, hospitals, and individuals in need.

But the story I think about most is this: a few years ago, Rechnitz heard about an orphan — a young man in Israel with no family and no money — who was getting married. The wedding was going to be tiny, almost empty. No parents to walk him down the aisle. No crowd of relatives dancing.

Rechnitz showed up. He didn't just send a check. He physically got on a plane, flew to Israel, walked into this small wedding, and told the couple he was covering everything. The music, the food, the flowers — everything. Then he danced with the chasan (groom) as if he were his own son.

My students always get quiet when I tell this story. In a world where billionaires are known for yachts and private islands, here's a man who uses his wealth the way the Torah envisions — to lift up the people who need it most. Rechnitz has done this kind of thing repeatedly, often anonymously. The wedding story only became public because other guests couldn't keep it to themselves.

Joseph Lieberman: Shabbos on the Campaign Trail

When Joseph Lieberman was chosen as Al Gore's running mate in 2000, becoming the first Jewish candidate on a major party presidential ticket, something interesting happened: the entire country suddenly had to learn what Shabbat meant.

Lieberman was openly, unapologetically Orthodox. He walked to the Capitol on Shabbat. He didn't campaign on Jewish holidays. When the campaign schedule conflicted with Shabbos, Shabbos won. His staff had to build an entire logistics system around the fact that their candidate was unreachable from Friday evening to Saturday night.

I remember watching his nomination speech and feeling a kind of pride I couldn't fully articulate. Here was a man on the national stage — literally one heartbeat from the presidency — and he wasn't hiding or downplaying his observance. He was matter-of-fact about it. "I'm an Orthodox Jew. This is what I do. This is who I am." And America, for the most part, respected it.

Lieberman showed that you could be ambitious and devout simultaneously. That keeping Shabbat wasn't a liability — it was a character trait. When he passed away in 2024, tributes came from across the political spectrum. People didn't just admire his politics. They admired his consistency.

Robert Aumann: A Nobel Prize and a Gemara

Dr. Robert Aumann won the Nobel Prize in Economics in 2005 for his work on game theory — the mathematical study of strategic decision-making. He's also an Orthodox Jew living in Jerusalem who learns Gemara regularly and has written about how his Torah study and his mathematical research complement each other.

This is not a man who keeps his religious life in a separate box from his intellectual life. He's spoken publicly about how the analytical rigor of Talmud study sharpened his mathematical thinking. The same skills — close reading, logical reasoning, considering multiple interpretations of a single statement — apply to both.

My husband, who learns Gemara every morning before work, loves bringing up Aumann when people suggest that religious study is somehow anti-intellectual. "The Nobel Prize committee disagrees," he says. I've heard him say it approximately forty times. It still works.

Herman Wouk: The Pulitzer Prize Winner Who Kept Shabbos

Herman Wouk, who lived to 103, wrote some of the most celebrated American novels of the twentieth century — "The Caine Mutiny" (which won the Pulitzer), "The Winds of War," "War and Remembrance." He was a giant of American literature.

He was also a committed Orthodox Jew who wrote one of the best books about Jewish observance ever published: "This Is My G-d." In it, he explained Jewish practice to a mainstream audience with warmth, clarity, and genuine love. He described Shabbat as "a day of profound rest and joy" and made it sound not like a restriction but like a gift.

Wouk was known for leaving Broadway rehearsals early on Friday afternoons. During the production of "The Caine Mutiny Court-Martial," the theater world had to accommodate his Shabbat observance. He didn't make a big deal of it. He just left when he needed to leave, came back when Shabbos was over, and wrote some of the best dialogue in American theater in between.

What Connects Them

When I look at these people — a real estate mogul, a chief rabbi, a billionaire philanthropist, a senator, a Nobel laureate, a novelist — what I see is not fame despite Orthodoxy. I see people whose religious commitments shaped the very qualities that made them extraordinary. The discipline of daily davening. The intellectual training of Torah study. The ethical framework of halacha. The practice of stopping, every single week, to remember what actually matters.

My students always leave that first-day lesson thinking bigger. Not necessarily about becoming famous — most of us won't be, and that's fine. But about the idea that being frum doesn't limit you. It structures you. It gives you a foundation strong enough to build anything on.

And if Paul Reichmann can stop a billion-dollar construction project for Shabbos, I think we can all manage to put our phones down for twenty-five hours. Just saying.
