Jewish Inventions That Changed the World

Jews have been inventing, innovating & quietly reshaping everyday life for thousands of years

Some of these contributions are small conveniences, others are cultural bedrocks, and a few have literally saved lives. Here are ten Jewish inventions and ideas that transformed the modern world, from the first video game console to monotheism itself.

1. Video Games: Ralph Baer

Before Fortnite, Super Mario, and Pac-Man, there was Ralph Baer, often called the father of video games.

A German-born Jewish engineer, Baer was expelled from school under anti-Jewish laws and emigrated to the United States. Working in the nascent electronics industry, he hit on the idea of making games that used a television screen.

He built the first video game console, nicknamed the Brown Box, because it was wrapped in brown tape to look like wood. Baer also created Simon, a simple memory game that became a decades-long favorite despite having no screen.

If you find yourself tapping, shooting, and whirling on a screen today, you can trace that lineage back to his inventions.

2. Stainless Steel: Hans Goldschmidt

Imagine building bridges, skyscrapers, airplanes, and surgical tools from metal that rusts and corrodes quickly.

That would make modern construction, transportation, and medicine much harder. The development of stainless steel changed all that.

In the late 19th century, German chemist Hans Goldschmidt found a way to produce carbon-free chromium, a key step that enabled the production of stainless steel. Today, stainless steel is essential across industries because it does not rust or corrode like ordinary steel.

3. Marvel Superheroes: Stan Lee

Stan Lee, the Jewish comic-book writer and editor, helped build the modern superhero universe.

He co-created iconic characters like Spider-Man, Thor, the X-Men, Iron Man, the Hulk, Black Widow, Black Panther, and the Avengers. These characters have had an enormous cultural impact through comics, TV shows, toys, and blockbuster films.

Lee’s stories often carried Jewish themes and sensibilities.

• He compared the Hulk to the golem from Jewish folklore
• He described Peter Parker as a neurotic New Yorker in a way that reflected Jewish self-awareness
• He used the X-Men to explore ideas about marginalization and otherness.
• Magneto, one of the X-Men’s primary antagonists, is explicitly written as a Holocaust survivor, a backstory rooted in Jewish history.

4. Pacemakers & Defibrillators: Paul Zoll

Before modern cardiac devices, doctors treating a stopped heart might literally open the chest and massage the heart by hand.

During World War II, Dr. Paul Zoll, a Jewish surgeon, treated soldiers with shrapnel wounds to the heart and noticed that a light touch or graze could make the heart jump an extra beat.

That observation led him to experiment with electrical stimulation to restart the heart outside the body. Zoll’s research paved the way for:

• Pacemakers
• External and implanted defibrillators
• Monitoring devices that keep track of heart rhythms

These devices have saved countless lives, and automated external defibrillators are now required in many public places, such as airports and schools.

5. Google: Two Grad Students at Stanford

In the mid-1990s, the early web looked very different: Netscape homepages, slow 800×600 screens, dial-up modems that paid by the hour. Surfing the web for more than a few minutes was rare.

Then two Stanford graduate students built a search engine that was far better than anything that existed at the time.

Their work revolutionized how we find information online. Today, Google is the most visited website in the world and powers services like Gmail, YouTube, and Google Maps, fundamentally changing how we navigate the internet and our daily lives.

6. Ballpoint Pen: László Bíró

Writing used to mean messy fountain pens that smudged and leaked.

Hungarian-Argentinian journalist László Bíró was fed up with ink stains and noticed that newspaper ink dried fast without smudging.

He experimented with that idea and invented a new tip: a small ball that spins in a socket, picking up ink from inside the pen and rolling it onto the paper.

Bíró eventually sold the idea to manufacturers, and the ballpoint pen became ubiquitous.

Today, more than 100 billion ballpoint pens have been produced, and in many countries, people still call the pen a biro after its inventor.

7. Drip Irrigation: Israeli Innovators

Water is everything in agriculture, and losing it to evaporation is a major problem in arid regions. Drip irrigation delivers water slowly directly to plant roots, minimizing waste and maximizing efficiency.

In the 1960s, an Israeli father-and-son team developed a highly effective microirrigation technique that helped turn barren desert into productive farmland.

Their innovations made Israel a global leader in agricultural water management, and drip irrigation systems now water millions of hectares worldwide.

8. Teddy Bear: Morris & Rose Michtom

The teddy bear has a surprisingly modern origin.

After a famous hunting story in which President Theodore Roosevelt refused to shoot a tied-up black bear, a Brooklyn couple, Morris and Rose Michtom, put a small stuffed bear in their candy shop window.

Customers went wild.

The bear was so popular that the Michtoms founded a toy company and mass-produced millions of the product.

They even gifted the original to President Roosevelt, and that first teddy bear now sits in the Smithsonian.

9. Polio Vaccine: Jonas Salk

Polio was once one of the most feared diseases, disabling or killing hundreds of thousands annually.

Jonas Salk, a Jewish virologist, developed an effective polio vaccine and famously chose not to patent it. “Could you patent the sun?” he asked, believing the vaccine should be available to everyone.

Within a decade, U.S. cases fell dramatically, from roughly 35,000 a year to just a few hundred, and now polio has been reduced to only a handful of cases worldwide thanks to vaccination campaigns.

10. Monotheism: The Core Idea of Judaism

Going back thousands of years, Judaism introduced a radical theological and moral idea: there is only one God.

This strict monotheism differed from other ancient religions that often acknowledged many gods with a chief deity.

Judaism’s monotheism shaped a new concept of a single moral source and later influenced the major monotheistic religions that followed, including Christianity and Islam.

Today, more than half the world’s population identifies with a monotheistic faith, a legacy that began with this foundational Jewish belief.

Jewish Inventors & Thinkers

From life-saving medical devices and revolutionary technologies to cultural icons and foundational religious ideas, Jewish inventors and thinkers have left an outsized mark on the modern world.
