Wartime Inventions

Why M&M's never melt in your hand: 10 wartime inventions

The phrase "Necessity is the mother of invention" is especially apt during wartime. During World War II, for example, soldiers needed lots of things to survive that didn’t exist yet. These inventors weren’t just scientists: mothers, businessmen, and car companies joined the challenge, too. When the Army asked, they took action and invented these 10 products that remained part of our everyday lives long after wartime.

Duct Tape Was Made to Protect Ammunition Cases

During World War II, the ammunition boxes sent to American troops were sealed with paper tape and dipped in wax to keep water out. Soldiers were supposed to pull a small paper tab to open them quickly. But the thin tape could tear, leaving them struggling to reach the ammunition. Vesta Stoudt, who packed and inspected these boxes at the Green River Ordnance Plant in Illinois, recognized this danger. She also had two sons serving in the U.S. Navy, so she devised a solution.

Stoudt proposed replacing the paper tape with a strong, waterproof cloth tape that soldiers could easily pull off. As she had no response from her supervisors, she wrote directly to President Franklin D. Roosevelt, including drawings of her idea. Roosevelt sent the proposal to the War Production Board, which asked a Johnson & Johnson operating company to manufacture the tape. It not only worked, but troops soon used the strong tape to repair boots and fix military vehicles too. Today, duct tape is still the solution to many everyday repairs.

M&M’s Were Designed With Soldiers in Mind

You probably remember the iconic M&M's slogan "melts in your mouth, not in your hand." Well, this characteristic was intentionally created for troops, allowing them to eat chocolate even under the hot sun.

When businessman Forrest Mars Jr. was travelling to Spain in the late 1930s during the Spanish Civil War, he observed how soldiers ate chocolate encased in sugar shells. The sugar crust prevented the chocolate from melting, and soldiers could enjoy the treat, even in hot temperatures. Mars soon partnered with Bruce Murrie, the son of Hershey's president, to secure a steady supply of chocolate for American troops. Their collaboration led to the creation of M&Ms, named after the initials of their last names. By 1947, the candy was made available to the public.

The Jeep Was Built for the U.S. Army

In 1940, the U.S. Army asked automakers to create a small four-wheel-drive vehicle that could carry soldiers across rough terrain. Bantam, Willys, and Ford entered the competition, and Willys won the main production contract. However, the final Willys MB also borrowed some of Ford’s flat grille and hood fastener design.

The new Jeep could travel through mud, climb steep roads, and reach places trucks couldn’t. Soldiers and mechanics could repair it quickly, and its parts were easy to remove and replace. Soldiers liked it so much that demand continued after they returned home, and Willys introduced the civilian CJ-2A in 1945 shortly after the war ended. The modern Jeep Wrangler still carries the same adventurous spirit.

The Slinky Started With a Naval Engineer’s Spring

In 1943, naval engineer Richard James was developing a spring to keep equipment steady on ships during rough seas. One day, he knocked one of his experimental springs onto the floor. Instead of falling in one place, it moved end over end. James rapidly realized its potential as a toy.

He spent the next two years finding the right size and tension for the spring. His wife, Betty, named it "Slinky," because of its smooth movement, and they introduced it to the market in 1945. But shoppers were confused and didn’t know what to make of it at first. The situation changed after James demonstrated it at a Philadelphia department store: all 400 Slinkys were sold in less than two hours.

Super Glue Emerged From Wartime Research

Today, we use Super Glue to repair broken items, for crafting, woodworking, and for countless quick fixes. But in 1942, chemist Harry Coover created it while trying to make a clear plastic for military gunsights during World War II. He was testing chemicals called cyanoacrylates when his team found that they stuck to almost everything they touched. As that feature made them unsuitable for the original project, the researchers moved on.

Coover encountered the chemicals again in 1951 while his team was developing materials for jet canopies. This time, he realized that their powerful bond was useful because it required no heat or pressure. Kodak later refined the adhesive and released it as Eastman 910 in 1958. That accidental discovery became widely known as Super Glue.

Silly Putty Grew Out of a Search for Synthetic Rubber

Silly Putty is that stretchy stuff that comes in plastic eggs and bounces and bends, depending on how you pull it. It was created during World War II, when rubber was needed for tires, boots, gas masks, and other military supplies. Japan’s expansion in Asia cut the United States off from much of its natural rubber, so American scientists were forced to look for a replacement.

In 1943, General Electric engineer James Wright mixed boric acid with silicone oil and created a strange, elastic material. It bounced higher than rubber, but it wasn’t strong enough for the military’s needs. General Electric shared samples with scientists, hoping someone might find a practical use for it. Meanwhile, people began passing it around at parties for fun. At one of them, hosted by a General Electric executive, businessman Peter Hodgson watched guests play with it, recognized its potential as a toy, named it Silly Putty, and in 1950, he commercialized it.

Frozen Orange Juice Was Developed for American Troops

Orange juice provides vitamin C, which supports the immune system and helps the body heal wounds. During World War II, the military understandably needed to make sure troops received enough vitamin C. However, regular frozen juice lost its fresh taste during storage and transport, sometimes developing a flavor compared to turpentine. So in 1942, the Army asked researchers to create a frozen version that could travel without losing its flavor.

And by 1945, scientists of the Department of Agriculture removed water from fresh juice at low temperatures and then added a little fresh juice back into the concentrate. The process preserved the orange oils responsible for its familiar taste. The Army ordered 500,000 pounds, but the war ended before the product could be delivered. Instead, it reached American grocery stores in 1946 under the name Minute Maid and soon became a breakfast favorite.

Penicillin Became Widely Available Through U.S. Wartime Production

Penicillin offered a powerful solution to bacterial infections, which could otherwise turn a small wound deadly. But there was still one major problem: even a small amount took a lot of time and effort to produce. With thousands of wounded troops needing treatment during combat, the Allies had to find a way to produce much more of it.

British researchers brought their work to the United States, where government laboratories and drug companies took on the challenge. Scientists then found that growing the mold in deep tanks with a corn-based liquid produced much larger amounts . By 1944, American factories were making enough penicillin to treat Allied troops wounded during the D-Day invasion.

Aerosol Bug Spray Protected Soldiers From Insects

A mosquito bite wasn’t just annoying during war; it could literally take a soldier out of action. In tropical regions, mosquitoes carried malaria and other diseases that sickened lots of soldiers. An easy way to kill insects in tents and planes was needed, and large sprayers weren’t that practical.

Department of Agriculture researchers Lyle Goodhue and William Sullivan developed a small pressurized canister that released insecticide as a fine mist. Nicknamed the "bug bomb," it allowed troops to spray an entire space in seconds. It was patented in 1943, and more than 40 million cans were produced for military use during the war. It didn’t take long for that same technology to be used for home repellents.

Synthetic Rubber Kept American Vehicles Moving

A great number of wartime items needed natural rubber. — to make tires, hoses, engine belts, seals, life rafts, gas masks, and many other waterproof parts . But after Japan captured major rubber-producing areas in Southeast Asia, the U.S. lost access to most of its supply. Recycling and rationing efforts helped, but it wasn’t enough.

The government took action and brought oil, chemical, and tire companies together to build a synthetic-rubber industry at home. Made mostly from petroleum-based chemicals, the new material could do many of the same jobs as natural rubber. U.S. production grew from only 230 tons in 1941 to more than one million tons in 1945. Synthetic rubber kept military vehicles moving during the war and remained essential for tires and other everyday products afterward.

Who was the real Paul Revere? 10 shocking facts beyond the legend

Image: Keith J Finks

Like many stories from early American history, the myth of the heroic patriot galloping through the midnight dark, shouting a legendary warning, has completely overshadowed the man. The real Paul Revere was a fascinating human being. He was a craftsman, an innovator, and a family man. Let’s pull back the curtain on the legend and look at ten surprising facts you probably never knew about America’s favorite midnight rider.

1
He was of French descent

While we think of Paul Revere as an early American icon, his roots lay across the Atlantic. His father, Apollos Rivoire, was a French Huguenot (a member of the French Reformed Church) who fled religious persecution and immigrated to Boston as a teenager.

To fit in his new home, Apollos Americanized the family name to "Revere". Paul was born in late 1734 or early 1735, the son of Apollos and a Boston local called Deborah Hichborn. Apollos was so interested in blending in that he never taught his children to speak and read French. In fact, a young Paul Revere even fought against the French as part of the colonial forces during the French and Indian War.

2
He was an accomplished artisan

Before he was a revolutionary, Revere was a master craftsman. He learned the art of silversmithing from his father and quickly gained a reputation as an accomplished artisan. He designed seals, coats of arms, plate engravings, and silver teapots.

Revere also used his engraving skills to create sharp political cartoons that mocked the British. His most famous artistic work was a sensationalized engraving of the 1770 Boston Massacre. It wasn’t entirely historically accurate, but it spread through the colonies, stirring up the anti-British sentiment that laid the groundwork for the Revolution.

3
He worked as an amateur dentist

Image: See page for author, CC BY 4.0, via Wikimedia Commons

When silversmithing work ran slow, Revere picked up a side hustle: dentistry. He started cleaning teeth and crafting dental prosthetics out of animal teeth and walrus ivory for the people of Boston.

This amateur dental career actually led to a major moment in American history. In 1775, Revere’s close friend, Dr. Joseph Warren, was killed at the Battle of Bunker Hill and buried in an unmarked mass grave by British soldiers. A year later, when the bodies were exhumed, the remains were unrecognizable. Yet, Revere was able to identify Warren’s body by recognizing the specific ivory tooth and custom wire bridge he had personally crafted for his friend. It’s widely considered one of the earliest documented cases of forensic dentistry in the United States.

He played a key role in early intelligence efforts

Long before the CIA existed, Paul Revere was working as a pioneer of organized American espionage. As a member of the Sons of Liberty, Revere wanted to track British movements closely. In 1774, he helped form a spy group known as "the mechanics" or the "Liberty Boys".

These men were Bostonian blacksmiths, artisans, and laborers who used their ordinary routines to watch British troops, listening for rumors of upcoming military actions. The spies would gather at the city’s historic Green Dragon Tavern to trade secrets and map out British movements.

5
Longfellow's inaccurate poem

If your knowledge of Revere comes from Henry Wadsworth Longfellow’s famous 1861 poem, "Paul Revere's Ride," you’ve been given a romanticized version of history. Longfellow wrote the poem nearly a century later, on the brink of the American Civil War, to stir up national pride.

In reality, Revere wasn’t a lone rider. The night of April 18, 1775, Revere set out with two other main horsemen: William Dawes and Dr. Samuel Prescott. As they triggered local alarms, dozens of other riders joined the effort. By midnight, more than 40 people were racing across the country, spreading the word. Furthermore, Revere never actually made it to his final destination of Concord. He was captured and briefly detained by a British patrol.

6
He didn’t even own a horse for his midnight ride

It’s hard to imagine the midnight ride without Revere’s faithful steed, but the truth is, Revere didn’t even own a horse when the fateful night arrived. Because he had to be quietly rowed across the Charles River, bringing a horse from Boston was out of the question.

Once he reached Charlestown, he had to find a ride. He ended up borrowing a horse from a sympathetic local merchant called John Larkin. Legend has it that this borrowed mare was named "Brown Beauty". Sadly, after Revere was captured later that night, the soldiers confiscated the horse, and she was never seen again.

7
He didn’t actually say THAT

Image: Leonard Everett Fisher, Public domain, via Wikimedia Commons

"The British are coming!" is one of the most famous quotes in American history, but Revere never said it. The countryside was crawling with British soldiers, so his mission had to be very quiet. Yelling at the top of his lungs would have landed him in military prison before he even left town. Instead, he went door to door delivering the warning quietly to specific patriots.

Also, the phrase wouldn’t have made sense to the colonists. At the moment in 1775, the colonists still considered themselves British citizens. Instead, historical accounts indicate that Revere used the phrase, "The Regulars are coming out!" "Regulars" was the standard colonial term for the standing British army troops.

8
His military record wasn't outstanding

Although Revere was a phenomenal community organizer and courier, his transition into traditional military leadership didn’t go smoothly. During the war, he served as a major and later a lieutenant colonel in the Massachusetts State Artillery. His military career hit a disastrous low point in the summer of 1779 during the Penobscot Expedition in modern-day Maine.

The mission was a total failure for the Americans. In the aftermath, Revere was accused of cowardice, laziness, and disobedience. He faced a court-martial and spent several years fighting to clear his name. He was ultimately acquitted of all charges in 1782, but the incident permanently tarnished his dreams of military glory.

Fatherhood came early… and often

If you think managing a household today is stressful, consider Paul Revere’s domestic life: he fathered an astonishing 16 children.

He had his first eight children with his first wife, Sarah Orne. Following her death in 1773, he remarried a woman called Rachel Walker, with whom he had another eight children. They crammed this huge family into a small townhouse at 19 North Square in downtown Boston. Amazingly for the 18th century, 11 of his 16 children survived to adulthood.

10
Revere Copper Products, Inc. is still in operation

Image: Jaclyn Vernace

After the Revolution ended, Revere left politics and went back to industry with some success. He opened a hardware store, a foundry, and the first rolling copper mill in the United States.

In fact, his business supplied the copper used to protect the hull of the USS Constitution. He also cast nearly 1,000 church bells, many of which still ring across New England today. Amazingly, the company he founded, Revere Copper Products, Inc., is still in business. Paul Revere passed away in 1818 at the age of 83, leaving behind a legacy more industrious than a single night’s ride.

America's most famous names

Bill Clinton wasn't born Bill Clinton—and that's just the start

Image: Cecil W. Stoughton, Public domain, via Wikimedia Commons

What if we told you that Bill Clinton wasn't born "Bill Clinton"? Or that Harry S. Truman's famous middle initial didn't actually stand for anything? And would you believe Lyndon B. Johnson went three months without a name? We've known about America's presidents our entire lives, so it's easy to assume there's nothing left to learn about them. But behind some of the most familiar names in U.S. history are stories stranger than fiction. From accidental initials that lasted a lifetime to surnames that changed completely, here are 10 surprising stories behind the names of American presidents.

1
Bill Clinton

Have you heard of Bill Blythe? Probably not, but you definitely know who he is: Bill Clinton, the 42nd president of the United States.

Born William Jefferson Blythe III on August 19, 1946, in Hope, Arkansas, Clinton never knew his biological father, who passed away in a car accident three months before he was born. His mother, Virginia Cassidy Blythe, later married Roger Clinton Sr. At 15 years old, Bill chose to take the surname Clinton, adopting the name of the man who had raised him .

Lyndon B. Johnson

Have you ever heard of a baby who went three months without a name ? As unusual as it sounds, one US president began life exactly that way.

The future Lyndon B. Johnson was born on August 27, 1908, near Stonewall, Texas. But instead of naming their newborn son, his parents found themselves in a standoff. According to historical records from the Miller Center at the University of Virginia, his mother, Rebekah Baines Johnson, wanted to name him Clarence, while his father, Sam Ealy Johnson, wanted the baby named after himself. Unable to agree, they left him officially unnamed, and for the first three months of his life, he was simply "Baby Boy Johnson." The deadlock finally ended when his mother gave in, and the future president was named Lyndon Baines Johnson , honoring Lyndon Baines, a family friend admired by his father.

3
Ulysses S. Grant

The 18th president of the United States wasn't born with the name we all know. He was born on April 27, 1822, in Point Pleasant, Ohio, as Hiram Ulysses Grant. So where did the famous "S." come from?

The answer is a paperwork mistake. In 1839, Ohio Congressman Thomas Hamer nominated the 17-year-old Grant to the US Military Academy at West Point. Knowing the young man went by Ulysses and that his mother's maiden name was Simpson, Hamer accidentally wrote "Ulysses S. Grant" on the nomination. Grant considered correcting the error, but eventually gave up, for two main reasons. He disliked the initials of his birth name, "H.U.G.", so the mistake didn't bother him much. In addition, fixing it would have meant a mountain of paperwork that could have jeopardized his appointment to West Point. So he simply let the new name stand, and the accidental middle initial stayed with him for the rest of his life.

4
Harry S. Truman

Harry S. Truman may have one of the strangest stories on this list.

His first name, Harry, honored his maternal uncle, Harrison "Harry" Young. His middle initial, however, didn't actually stand for anything. Truman's parents chose the "S" to honor both of his grandfathers, Anderson Shipp Truman and Solomon Young, without choosing one name over the other. In other words, the "S" wasn't short for Shipp or Solomon; it was simply "S". Truman himself usually wrote it without a period, since it wasn't an abbreviation. But after he became president, his staff encouraged him to add the period in official correspondence because it looked more conventional. That's why today he's almost always remembered as Harry S. Truman.

5
Dwight D. Eisenhower

President Dwight D. Eisenhower is remembered for leading the nation through the Cold War and signing the Civil Rights Act of 1957. But there's one surprising detail about him that most people never hear.

The man we know as Dwight Eisenhower was actually born David Dwight Eisenhower on October 14, 1890, in Denison, Texas. Named after his father, David Jacob Eisenhower, he quickly ended up with a problem: there were now two Davids in the same household. To avoid the confusion, his mother, Ida, simply began calling her son Dwight instead. He went by his middle name as if it were his first for years, but the change didn't become official until he applied to West Point at age 20. Wanting his official records to match the name everyone already knew him by, he registered as Dwight David Eisenhower and made the switch permanent.

6
Gerald R. Ford

On July 14, 1913, a baby boy named Leslie Lynch King Jr. was born in Omaha, Nebraska, and 61 years later, he became the 38th president of the United States. If the name doesn't sound familiar, there's a good reason: he entered the White House under a completely different name.

Leslie Lynch King Jr. was named after his father. However, just 16 days after his birth, his mother, Dorothy, fled the marriage with her infant son to escape her abusive husband. Three years later, she divorced King and married Gerald Rudolph Ford, a paint salesman who raised the boy as his own. From then on, everyone knew him as Gerald Rudolph Ford Jr. , even though he didn't legally change his name until December 3, 1935, when he was 22 years old.

7
Ronald Reagan

Have you ever heard of "Dutch" Reagan? Perhaps not, but that was in fact the childhood nickname of Ronald Reagan, the 40th president of the United States.

Born as Ronald Wilson Reagan on February 6, 1911, in Tampico, Illinois, Reagan got his nickname from his father, who thought his newborn son looked like a "fat little Dutchman." The moniker stuck almost immediately. As a boy, Reagan embraced it so completely that, according to his autobiographies and records at the Ronald Reagan Presidential Library, he disliked being called Ronald and insisted everyone call him Dutch instead. That changed only after he arrived in Hollywood in the late 1930s, when studio executives convinced him that "Dutch Reagan" wasn't exactly leading-man material.

8
Jimmy Carter

Born James Earl Carter Jr. on October 1, 1924, in Plains, Georgia, and named after his father, the future president had been called "Jimmy" almost from the day he was born.

Over the years, the nickname became the name he truly identified with. So when he took the presidential oath in 1977, Carter broke with tradition. Instead of using his formal first name like all the presidents, he was sworn in as Jimmy Carter, becoming the first (and still the only) US president to take the oath of office using a nickname rather than his legal name.

9
John Quincy Adams

The second president of the United States, John Adams, is one of the best-known Founding Fathers. His name is instantly recognizable to most Americans, and that's exactly why his son made an important decision about what he would be called.

John Quincy Adams was born on July 11, 1767, in the North Precinct of Braintree, Massachusetts, an area that was officially renamed Quincy in 1792. The nation's sixth president and the first son of a president to become president himself carried a name with a story. He was named not only after his father, but also after his maternal great-grandfather, Colonel John Quincy, who was gravely ill when the baby was born. Although Quincy was originally a family surname, it became the baby’s middle name. As an adult, he embraced all three names, John Quincy Adams, helping distinguish himself from his famous father while honoring both sides of his family.

10
Grover Cleveland

Image: National Archives at College Park, Public domain, via Wikimedia Commons

Most people have never heard of Stephen Cleveland, but mention Grover Cleveland, and they'll know exactly who you're talking about. The thing is, they're the same person.

Born on March 18, 1837, in Caldwell, New Jersey, the future 22nd and 24th president of the United States was actually named Stephen Grover Cleveland. His father, a Presbyterian minister, chose the name to honor Reverend Stephen Grover, the first pastor of the First Presbyterian Church in Caldwell, where he was serving at the time. As he grew older, however, Cleveland made an unusual choice: instead of going by his first name, Stephen, he adopted his middle name because he simply liked the sound of "Grover Cleveland" better.
