Did you know that 🤔🤔🤔

Sometimes a simple mistake can change the course of medical history.

Late one evening in 1956, engineer Wilson Greatbatch was working in a laboratory at the University at Buffalo on a device designed to record heart rhythms. Tired after a long day, he accidentally picked up the wrong resistor from a box. Instead of the required 10 kΩ resistor, he soldered a 1 MΩ resistor into the circuit.

When he turned the device on, something unexpected happened. The instrument didn’t record anything. Instead, it began to produce clear pulses — once every second. Exactly like the rhythm of a human heart.

In that moment, Greatbatch realized: this is how a device that stimulates the heart should work.

In the 1950s, heart disease was often a death sentence. Early pacemakers were the size of a television, powered by a wall outlet, and delivered electrical impulses through the skin. Patients were literally tethered to the wall with wires.

Greatbatch believed the device should be small enough to be placed inside the human body.

Many doctors thought the idea was unrealistic. The human body is a harsh environment that can quickly damage metal and electronics. But the engineer didn’t wait for approval. He invested his own savings — $2,000 — set up a small laboratory in a shed, and together with his wife Eleanor began building a prototype.

For two years he worked to find a way to protect the electronics from moisture.

In 1960, at a hospital in Buffalo, a 77-year-old man became the first patient to receive the device. Surgeons implanted the pacemaker, about the size of a pocket watch, and connected electrodes to his heart. When the external machine was turned off, his heart continued beating on its own.

The patient was able to leave the hospital and lived for another 18 months.

Today, nearly 1 million pacemakers are implanted worldwide every year.

Wilson Greatbatch, the author of more than 150 patents, passed away in 2011 at the age of 92.

His story reminds us of something powerful:
sometimes the “wrong” part turns out to be exactly the one that gives people hope… and more time. ❤️

Brother vs. Brother: The Family Feud That Created Adidas and Puma

Imagine a town where people don’t look you in the eye first — they look at your shoes.

For decades, that was the reality in the small German town of Herzogenaurach. The story of Adidas and Puma isn’t just a business tale. It’s the story of a family conflict so intense that it reshaped the global sports industry.

From Perfect Partnership to Bitter Rivalry

In the 1920s, the Dassler brothers were unstoppable.

Adi Dassler was the genius craftsman. He could build athletic shoes from almost anything — even scraps of military equipment.
Rudi Dassler was the master salesman. He had the charisma to convince any athlete that their shoes would bring victory.

Together, they reached global fame when athletes wearing their footwear dominated the 1936 Olympic Games.

But by 1948, the partnership collapsed.

The brothers’ relationship had deteriorated so badly that they split their factory in half. Each took part of the machines and exactly half of the employees.

From that moment, two legendary brands were born:

• Adidas — named after Adi Dassler
• Puma — Rudi’s company (which he briefly called “Ruda” before changing the name)

A Town Divided

Their rivalry didn’t just affect business — it split the entire town.

Herzogenaurach became almost like a battlefield.

• Social divisions: Employees of Adidas avoided bars where Puma workers gathered.
• Economic loyalty: Even local craftsmen had to be careful — showing up to a Puma customer wearing Adidas shoes could cost them the job.
• “The town of bent necks”: Locals developed the habit of glancing at people’s shoes first to see which side they belonged to.

The Battle for the World’s Athletes

Competition between the brands extended to the world’s biggest sporting events.

One famous example happened during the 1970 FIFA World Cup final.

Puma secured a deal with football legend Pelé. Just before kickoff, with cameras from around the world focused on him, Pelé bent down to tie his shoelaces.

Millions of viewers suddenly saw the Puma logo.

It was a brilliant marketing move — and it reportedly drove Adi Dassler furious.

Even in Death, the Distance Remained

The Dassler brothers never reconciled.

When they died, they were buried in the same cemetery — but at opposite ends, ensuring even in death there was distance between them.

Only in 2009, long after both brothers were gone, employees of Adidas and Puma played a symbolic football match to mark reconciliation.

Yet even today, in Herzogenaurach, some locals still instinctively glance at your sneakers first.

Why This Story Matters

This story reminds us that competition isn’t always about markets or numbers.

Sometimes it’s about something far more personal — the desire to prove to someone close to you that you are better.

And in this case, a family feud helped create two of the most iconic sports brands in the world.
