Harriet Tubman secretly worked as a Union spy

Most Americans know Harriet Tubman for her leadership of the Underground Railroad, but during the Civil War, she also became a Union scout and spy in South Carolina. Working with Colonel James Montgomery, Tubman gathered intelligence from enslaved people living behind Confederate lines near the Combahee River .

In June 1863, Tubman helped lead the Combahee River Raid, guiding Union gunboats through Confederate waters filled with hidden mines. The operation freed more than 700 enslaved people and made Tubman the first woman known to lead a major U.S. military mission.

Julia Child worked for the U.S. intelligence agency

Before becoming television’s most famous chef, Julia Child joined the Office of Strategic Services, or OSS, in 1942 during World War II. The OSS later evolved into the CIA. Too tall to enlist in the Women’s Army Corps, Child instead classified files and overseas communications in Asia.

One of her strangest assignments involved helping researchers develop shark repellent for Navy explosives and emergency rescue kits . The repellent used copper acetate and black dye to create an odor similar to a dead shark.

Benjamin Franklin conducted unofficial spy work in Europe

Benjamin Franklin was more than a scientist and Founding Father. During the American Revolution, he quietly acted as an intelligence organizer while serving as ambassador to France beginning in 1776 . Franklin cultivated secret alliances, intercepted information, and used coded correspondence to support the colonies’ fight against Britain.

Operating from Paris, Franklin built relationships with French officials and helped persuade France to support the American cause with money, troops, and naval power. Historians consider his diplomatic intelligence efforts essential to the American victory at Yorktown in 1781 and eventual independence.

Louisa May Alcott published thrillers under another name

Louisa May Alcott became a literary icon after publishing Little Women in 1868, but few readers knew that she had already written sensational thrillers under the pen name "A.M. Barnard." These stories featured revenge, hidden identities, forbidden romance, and dramatic crime plots that shocked Victorian audiences.

Alcott used a pseudonym because publishers often expected women writers to produce respectable domestic fiction. Many of her darker stories remained forgotten until scholars rediscovered them in the 1940s. Today, titles like Behind a Mask reveal a far more rebellious side of the beloved author.

Maya Angelou worked as San Francisco’s first black female cable car conductor

Long before becoming a celebrated poet and author, Maya Angelou made history in San Francisco during the 1940s. At only 16 years old, she applied repeatedly for a conductor job on the city’s cable cars after seeing an advertisement that excluded Black applicants .

Angelou refused to give up despite repeated rejection. She eventually became San Francisco’s first Black female cable car conductor in 1944. Years later, she described proudly wearing the blue uniform while working long shifts across the city before launching her writing and civil rights careers.

Dr. Seuss created classified wartime propaganda films

Before writing Green Eggs and Ham and The Cat in the Hat , Theodor Geisel, better known as Dr. Seuss, worked on wartime propaganda during World War II. Between 1943 and 1945, he joined director Frank Capra’s Signal Corps unit to produce military training films for American soldiers .

Geisel also drew political cartoons supporting the Allied war effort and criticizing fascism. Some of his films were classified during the war because they contained military training material. His animated work helped explain battlefield strategy and morale issues to thousands of U.S. troops overseas.

Babe Ruth once played an entire game with a fever over 102 degrees

In 1925, Babe Ruth became seriously ill during spring training and collapsed while traveling by train . Newspapers nicknamed the incident "the bellyache heard around the world." Reports from the time described Ruth suffering from a fever above 102 degrees while still insisting on returning to baseball activities.

Despite his condition, Ruth’s determination became part of baseball legend. The illness hurt his performance during the 1925 season, when the New York Yankees finished seventh in the American League. Even so, Ruth rebounded quickly and helped lead the Yankees to championships in later years.

Harry Houdini worked with police departments

Harry Houdini’s famous escape acts fascinated police departments across America and Europe in the early 1900s. Officers regularly challenged him to escape from handcuffs, prison wagons, and locked jail cells. Houdini often invited local police to inspect restraints before his performances began.

Beyond entertainment, Houdini also worked closely with law enforcement to expose fraudulent mediums and fake spiritualists during the 1920s . Using his knowledge of locks, hidden compartments, and deception, he publicly demonstrated how many supposed supernatural tricks were actually carefully staged illusions.

Frank Lloyd Wright hid a private apartment inside one of his buildings

Architect Frank Lloyd Wright secretly maintained a private apartment inside his famous Oak Park Studio near Chicago, Illinois. Built in the 1890s, the studio served as both his workplace and personal retreat while he designed many of his early Prairie-style homes across the Midwest.

The hidden living quarters allowed Wright to work late into the night and host select guests away from public attention. The building itself became one of the most important centers of American architecture, producing groundbreaking residential designs that influenced modern architecture around the world.

Muhammad Ali quietly funded humanitarian causes for years

Muhammad Ali’s boxing fame often overshadowed his enormous charitable work. For decades, Ali quietly donated money to hospitals, food programs, children’s charities, and international humanitarian efforts . Friends and family later revealed that many of his contributions were intentionally kept private.

In 1990, Ali traveled to Iraq during tensions leading up to the Gulf War and helped secure the release of 15 American hostages. He also supported global relief organizations and Parkinson’s disease research after his own diagnosis. In 2005, President George W. Bush awarded Ali the Presidential Medal of Freedom.

Carhenge

The gray megaliths of Stonehenge , in contrast with the bright green of the surrounding plains, create an image familiar to most of us. The ancient monument in the south of England inspired artist Jim Reinders to design this roadside attraction near Alliance, Nebraska, along Highway 87.

He and his family built it in 1987 on his late father’s farm as a memorial. Thirty-nine cars were buried and welded in place, then spray-painted gray to form a structure imitating the original. Carhenge remains open 24/7, and anyone is welcome to visit anytime, but it looks particularly epic against the setting sun.

Prada Marfa

"Wait, what was that?" Imagine driving along U.S. Route 90 and catching a flashing glimpse of this lone-standing, one-story, deserted Prada store , just feet away from the road. Located 26 miles northwest of Marfa, Texas, this storefront is a land art installation built in 2005 by the architects and artists Elmgreen & Dragset.

It wasn’t meant to be an advertisement for the brand, although the shoes and handbags displayed in the interior of the shop were provided by designer Miuccia Prada herself. The location was carefully chosen so that the white shop would stand out against the barren landscape.

"Giant" Marfa Mural

Remember Giant (1956), the film starring Elizabeth Taylor, Rock Hudson, and James Dean? This classic about a wealthy Texan family was shot around the town of Marfa, Texas, and parts of it were filmed right at this spot. That means Marfa became the site of yet another car-stopping roadside attraction.

Right off the road on U.S. ​​Highway 90, just like the Prada Marfa, stand these colorful plywood murals that depict the characters and the Little Reata Ranch , which served as the backdrop of the movie. Artist John Cerney erected these figures in 2018, and visitors also mention that one can hear music at the site: it comes from speakers cleverly concealed between rocks and was composed by Michael Nesmith from The Monkees.

Galleta Meadows Sculptures

You would have to take a 14-mile detour from California State Route 78 to see them, but it would be worth it. Galleta Meadows is a privately owned, open-to-the-public estate that has been home to over 130 giant metal sculptures created by Ricardo Breceda since 2007.

Breceda first built a giant metal dinosaur for his daughter after watching Jurassic Park III with her. When the owner of this estate saw his art, he commissioned all the sculptures that now adorn the land. The figures emerging from the ground vary. Beyond the mythological serpent dragon, some represent animals that once roamed the same land, such as the Columbian mammoth, the sabertooth tiger, and dinosaurs. A scorpion, a grasshopper, and a bighorn sheep can also be found.

Seven Magic Mountains

The hoodoos that characterize the Western landscape inspired this pop-art image in the mind of Swiss artist Ugo Rondinone. Located on Las Vegas Boulevard ten miles south of Las Vegas, Nevada, these stacks of boulders were painted with fluorescent pigments that are activated by the sun.

The installation, built in 2016, was funded by the Nevada Museum of Art and the Art Production Fund . It was originally intended to remain for two years, but the fascination with this highly photogenic landscape was such that it was decided to keep it in place and open to the public. The Seven Magic Mountains receive around 325,000 visitors every year.

Cabazon Dinosaurs

One of the most famous roadside attractions in the U.S. is the Cabazon Dinosaurs, located just west of Palm Springs in California. These are two steel-and-concrete figures, about 20 feet tall, that have their own names: the Brontosaurus Dinny the Dinosaur and the T-Rex, Mr. Rex.

Dinny and Mr. Rex are repainted frequently to show varying colors and suits. A nearby museum gift shop houses over 100 dinosaur figures and animatronics. The stop became even more famous after being featured in Tim Burton’s Pee-wee's Big Adventure (1985), but they had been standing at Cabazon since artist Claude Bell began building them in 1964.

Salvation Mountain

In the California Desert, not far from State Route 111, stands an artificial hill that was created in 1984 and has been repeatedly modified over the years to become a colorful folk site. Local resident Leonard Knight started building the hill in the 1980s, with the vision that it would forever hold a message of "unconditional love to humankind ."

Adobe bricks, straw, discarded tires and car parts, and tons of paint were all used in the production of this 150-foot-wide art project.

Enchanted Highway

The Enchanted Highway stretches for 32 miles in the southwest of North Dakota. It has been decorated with some of the world’s largest scrap metal sculptures, all made by local artist Gary Greff, who began the project in 1989. He started the project as a way to revive his town, Regent , while it was in economic decline.

Fish, pheasants, bugs, and even a "Tin Family" of humans adorn the landscape near the city of Dickinson. Nine sites with sculptures are built along County Highway 21, most of them featuring parking areas to allow visitors to wander near the sculptures and take plenty of pictures.

Peachoid

The Peachoid water tower stands in Gaffney, South Carolina, and is shaped like, well, a peach . The tank holds one million gallons and is visible from miles around the point at Interstate 85 where it stands.

It was built for the city of Gaffney in 1981, resembling the fruit for which they were best known. It was commissioned by the Gaffney Board of Public Works, which also wanted to make the statement that Cherokee County, at one point in history, was a bigger peach producer than the entire "Peach State," Georgia.

Garden of One Thousand Buddas

Would you count them? There’s a peaceful garden in a valley near Glacier National Park in Montana. In it live one thousand white statues of sitting Buddhas lining a public park and botanical garden.

The construction of the site, nestled by the Mission Mountains , began in 2000. It wasn’t until 2015, however, that the 1,000th Buddha was finally placed, reaching the original goal of the founder, a Tibetan master. Hundreds of visitors arrive each week to walk the garden and wander around the 10 acres it spreads over.

The Battle of Los Angeles (1942)

On the night of February 24th, 1942, a few months after the Pearl Harbor attack, sentinels identified what they thought was an aircraft near Culver City, which prompted them to fire over 1,440 anti-aircraft shells into the sky.

The enemy was never identified, and no bombs were dropped, although the chaos caused by the shooting resulted in five civilian casualties. The event was later reported as a false alarm, but to this day no one knows what caused the uproar , though some theories suggest it was a weather balloon, a tray bird, or a weather phenomenon.

The Great Molasses Flood (1919)

We’ve heard about disasters caused by heavy rains, overflowing rivers, and mudslides, but how often are they caused by syrup? For Bostonians, it was at least once, on January 15, 1919. A 50-foot-tall and 90-foot-wide steel tank owned by the United States Industrial Alcohol Company burst , releasing 2.3 million gallons of molasses into the streets.

A wave of molasses from 25 to 40 feet high swept through Boston's North End, toppling buildings and infrastructure , taking the lives of 21 people and several animals, and injuring at least 150 people. The cleaning efforts took weeks to remove the residue from the street, and a lawsuit against the company resulted in reforms in engineering, building codes, and safety certification.

3

The sliced bread ban (1943)

Pre-sliced bread is one of the comforts of modern life we take for granted now, but there was a time when it was banned as part of the war effort. On January 18, 1943, the American government decided to ban the sale of sliced bread to reduce the use of steel (used for slicing machines) and wax paper (used for wrapping the bread).

The measure was not only unpopular but also ineffective, as it didn’t make a real difference in wax paper and steel savings . The seemingly easy task of slicing bread by hand caused an uproar across the country, and bread sales dropped, forcing the government to lift the ban only two months after.

The Ohio "Toledo War" (1835)

Border disputes among states are not uncommon in American history, usually settled in court and unlikely to result in a military standoff. But sometimes they do, as in 1835, when Ohio and Michigan (then still a territory) quarreled over the Toledo Strip, a 468-square-mile piece of land with critical access to Lake Erie . Official boundary demarcations were vague, so control over the area was asserted by constructing roads and collecting taxes in the case of Michigan, and by involving Congress and creating demarcation lines in the case of Ohio.

National intervention proved necessary when both governors mobilized their militias, and President Jackson mediated in the dispute. The Toledo Strip was given to Ohio, but in turn, Michigan was granted statehood , and the Upper Peninsula was added to its territory. While the conflict was luckily bloodless, it’s at the root of the historic rivalry between Michigan and Ohio.

5

The Salem tomato trials (1820)

Although Salem, Massachusetts, is famous for its witch trials, this particular case takes us to Salem, New Jersey. In 1820, tomatoes had already been popularized worldwide, but some people still had reservations because they were rumored to be poisonous . Robert Gibbon Johnson, a wealthy local farmer, decided to dispel the stigma and sponsored competitions for the largest tomato grown, which sparked an uproar and drew in the local courts.

According to the story, Johnson arrived at court with a basket full of tomatoes and proceeded to eat them all in front of the crowd. As he didn’t die or become violently ill, it was proven that tomatoes were safe for consumption.

6

The Battle of Athens (1946)

The Greek city of Athens claims to be the birthplace of democracy, but Athens, Tennessee, has also done its part to ensure the safeguarding of democratic values. In the 1940s, McMinn County in Tennessee was part of a criminal network involving politicians and law enforcement, who randomly detained citizens under false charges to collect fines. The system was dependent on rigged elections, so when armed deputies locked themselves with the ballot boxes in the county jail during the August 1, 1946 elections, the people of Athens and Etowah took matters into their hands.

Around 200 veterans, recently returned from WWII, raided the National Guard Armory for guns and ammunition, and laid siege to the jail. After a gunfight that lasted through the night, they breached the entry using dynamite and secured the ballot boxes , which were then counted in public, resulting in a landslide victory for the opposition. All the firearms were then cleaned and quickly returned to the armory, and no criminal charges were raised against the veterans on account of their righteous intentions.

7

The pig war (1859)

The U.S. and the U.K. have gone to war more than once, but only one time was a pig the cause of the conflict. In 1859, the San Juan Islands (now part of Washington state) were a disputed territory between America and the U.K. as a result of vague wording in the 1846 Oregon Treaty. The diplomatic dispute quickly turned into real conflict when an American farmer in one of the islands shot a pig that regularly dug into his garden.

As it turned out, the pig belonged to an employee of the British Hudson's Bay Company. Although the farmer offered to pay for the animal , its owner demanded higher compensation, and British authorities threatened to arrest the farmer . This caused the American settlers to petition for military protection, and both countries mobilized troops into the area. The conflict was resolved through international mediation 12 years later in favor of the United States, with the pig as the only casualty.

8

The child mailing system (1913)

The railroad and the establishment of a national postal system did wonders for communication in America, but sometimes it led to controversial and potentially dangerous situations, such as the child mailing system. In 1913, the U.S. Post Office Department launched a parcel post service for packages up to 11 pounds. The content of the parcels was not clearly delimited, and people started using it to send for small children , as it was cheaper than paying for a train ticket.

Children as small as 8-month-olds were mailed (although unwrapped) with postage stamps attached to their clothes and under the care of railroad workers. The system was short-lived, as the Postmaster General banned the mailing of children as soon as he learned about it, claiming they didn’t count as "harmless live animals".

Project Acoustic Kitty (1960s)

At the height of the Cold War, espionage had turned into an art form, with agencies on both sides of the conflict resorting to all kinds of methods to gather sensitive information, including the development of technological gadgets and the recruitment of non-human agents . "Project Acoustic Kitty" was one of the CIA’s attempts, aiming to infiltrate the Kremlin and the Soviet embassies with the help of surgically modified cats.

The cats underwent surgery to implant a microphone into their ear canal and a transmitter into their body, allowing them to record and transmit sound from their surroundings. The cats would then be released near the target location, hoping to pick up conversations between Soviet diplomats and office workers. According to some sources, the first mission ended abruptly when the cat in question was struck by a taxi, but CIA former officials claim that the project never prospered due to the difficulty in training the cats.

The Year Without a Summer (1816)

In 1816, North America (as well as part of Europe) experienced freezing cold temperatures during Spring and Summer, all thanks to an Indonesian volcano. In April 1815, the Indonesian Mount Tambora experienced a massive volcanic explosion, releasing millions of tons of ash, dust, and sulfur dioxide across the world , which created a shield in the stratosphere, blocking sunlight.

In America, the event manifested as a fog that was not dispersed by rain or wind, and the lack of sunlight resulted in frost and snow during late Spring and early Summer, especially across New England. While the low temperatures themselves were not as taxing on the population, they were detrimental to the crops and livestock, creating food shortages and causing thousands of families to relocate to different regions of the country to escape famine and poverty.
