In the 1920s, young women were told radium was harmless.

They painted their teeth with it. They even licked their brushes.

Months later, their bones glowed in the dark, and their jaws crumbled from their faces.

This is the horrifying true story of the Radium Girls: Image
Image
In the 1910s, radium was the wonder element.

It was sold in face creams, energy tonics, and even toothpaste.

People believed it gave life.

No one realized it was lethal except the companies that used it.
During WWI, U.S. Radium Corp hired teenage girls to paint watch dials with glow-in-the-dark paint.

The paint made the numbers glow at night, which was crucial for soldiers in WWI.

The rate of pay was about a penny and a half per dial.

But there was a deadly secret. Image
Image
To get a fine brush tip, girls were taught to put the brush in their mouths, over and over.

They swallowed radium dozens of times a day.

Supervisors told them it was harmless and even healthy.

Some girls painted their teeth, nails, and faces for fun.
At night, they’d walk home with glowing hair and clothes.

They thought it made them look like angels.

In truth, their bones were becoming radioactive. Image
Soon, the girls started losing teeth.

Their jaws developed abscesses.

Dentists described one girl’s jaw as “falling out in pieces.”

The radium had seeped into their bones, glowing from within.
U.S. Radium knew radium was dangerous.

Male lab workers wore lead aprons and masks.

But the female dial painters were told: “It’s safe enough to eat.”

When girls got sick, the company blamed syphilis for destroying their reputations. Image
Image
In 1922, Mollie Maggia, 24, died in agony.

Her jawbone was removed during an autopsy, still glowing.

Dozens more followed, dying from anemia, cancer, or necrosis.

Some glowed in the dark in their coffins. Image
Five women: Grace Fryer, Edna Hussman, and three others sued U.S. Radium.

They could barely walk.

Grace wore a back brace just to sit upright in court.

The case became a national sensation. Image
Newspapers called them “The Living Dead.”

U.S. Radium fought dirty.

They tried delaying the trial until the women died.

But the public outrage was too great. Image
In 1928, the women won.

Each got $10,000 (about $180,000 today), medical expenses, and $600 a year for life.

But most didn’t live long enough to collect. Image
In Illinois, Radium Dial repeated the same crime.

More girls died.

One woman’s body was exhumed decades later, and her skeleton was still glowing. Image
The Radium Girls’ suffering forced companies to provide worker protections.

It led to labor laws, OSHA, and radiation safety standards.

They died, but they saved millions of lives. Image

In 1983, one man had 10 minutes to decide the fate of the world.

Stanislav Petrov sat at his console as alarms blared: 5 U.S. nuclear missiles were "en route" to Russia.

He had two choices: launch a counterstrike or trust his gut.

What he did next saved humanity. Here's how 🧵 Image
Image
In the 1980s, during the Cold War, the Soviets introduced a satellite-based early-warning system designed to detect U.S. missile launches.

While this technology represented a significant leap forward, it was far from perfect, a fact that would become painfully clear. Image
Petrov was stationed at Serpukhov-15, a Soviet early-warning command center outside Moscow.

His role was to monitor satellite data and alert his superiors of any imminent U.S. missile launches.

At 12:15 a.m., alarms blared. Image

In 1933, a wealthy doctor kept his dead lover’s body hidden in his apartment.

He dressed her, dined with her, and even slept beside her corpse for years.

This is the horrifying true story of Carl Tanzler: the man who married a dead woman: 🧵 Image
Image
Carl Tanzler was a German-born radiologist.

In 1927, he moved to Key West, Florida, to work at a U.S. Marine hospital.

He was eccentric, secretive, and claimed to have “visions” of a dark-haired woman who would be his true love. Image
In 1930, a beautiful 21-year-old Cuban-American woman named Maria Elena Milagro de Hoyos (Elena) was admitted to the hospital.

She was suffering from tuberculosis, a disease often fatal at the time.

When Tanzler saw her, he claimed she was the woman from his visions. Image

In 1961, the Soviets built the most powerful nuclear bomb ever.

It was 3,800 times stronger than the bomb dropped on Hiroshima.

So destructive that the man who built it spent the rest of his life trying to stop nuclear weapons.

This is the story of Tsar Bomba: Image
Image
The late 1950s saw the United States and the Soviet Union locked in an arms race, each trying to outmatch the other.

But in 1958, a moment of hope appeared: a voluntary nuclear test ban agreement.

For a brief moment, sanity seemed possible. Image
But everything changed in May 1960.

An American U-2 spy plane was shot down over Soviet territory.

The United States denied it was a spy plane, but the captured pilot exposed the lie.

The Soviets were outraged.

In 1910, America’s banking system was collapsing.

Six men with 1/4 of the world’s wealth boarded a train in secret to a private island.

There, they created the blueprint for the Federal Reserve.

Here's the untold story of the most powerful institution in U.S. history 🧵 Image
Image
In the early 1900s, U.S. banking was chaotic.

Banks were small, unregulated, and prone to collapse.

The Panic of 1907 triggered mass bank runs.

The U.S. economy nearly imploded, and Congress was desperate for a fix.
Senator Nelson Aldrich, head of the National Monetary Commission, quietly invited 5 of the nation’s top financiers:

1. Paul Warburg – Kuhn, Loeb & Co.

2. Frank Vanderlip – National City Bank of New York (Citibank)

3. Henry P. Davison – J.P. Morgan & Co. Image

In 1347, the Black Death killed 50 million people (50% of Europe) in just 5 years.

It wasn’t just a plague but a nightmare that rewrote history.

Here’s how the deadliest pandemic in history changed the world forever: Image
Image
The plague began far from Europe.

Historians believe it originated somewhere near the Gobi Desert or the Mongolian steppes.

Some pointed to Lake Issyk-Kul, where strange deaths had been reported as early as the 1330s.
In 1343, the Mongol leader Janibeg laid siege to the Genoese trading city of Caffa (Feodosia).

As his army camped outside the town, something strange happened: his soldiers began dying.

They developed swollen buboes, high fevers, and vomited blood before succumbing within days.

In 1944, a German U-boat vanished with 50 men on board.

For decades, no one knew what happened.

66 years later, a diver found it 400 feet below the Bay of Genoa.

The crew was still sealed inside.

This is the haunting story of U-455: a WWII mystery buried beneath the sea. Image
Image
During WWII, German U-boats were known as the "Grey Wolves."

They prowled the oceans, targeting Allied supply ships with ruthless precision.

These submarines were celebrated in Nazi propaganda as symbols of invincibility, and their crews were considered elite soldiers.
But the discovery of U-455 challenged the notion of U-boat dominance and raised questions about its tragic end.

The discovery of U-455 sparked an investigation led by divers, historians, and military experts.

Among them was Roberto Rinaldi, a former Cousteau crew diver.
