Abraham Lincoln

Political life usually comes with a few disappointing election nights. Long before he was memorialized on Mount Rushmore, Abraham Lincoln spent decades collecting setbacks.

He went into business with a partner in Illinois in 1833 by purchasing a general store. Known as the Berry and Lincoln store, the enterprise failed due to poor sales, leaving him in debt for years. He ran for the state legislature and lost. He served in the Illinois militia during the Black Hawk War in 1832 and was demoted from captain to private. Over the following years, he ran for office again and again, including two unsuccessful bids for the U.S. Senate, and lost most of them. Regardless of that, he kept showing up, and in 1860, he won the presidency and went on to guide the country through the Civil War and end slavery. Friends who knew him in his Illinois years later said what stood out most wasn’t his brilliance, but how he never let defeat be the last word.

Elvis Presley

Picture a then-unknown Elvis Presley in 1954, long before the jumpsuits, sold-out arenas, and screaming fans. He was only 19 and still trying to figure out where his unusual blend of country, blues, and rhythm and blues belonged.

Elvis had just released his first single and was invited to perform at the Grand Ole Opry in Nashville, a stage that represented the pinnacle of country music. He sang a rockabilly-tinged version of "Blue Moon of Kentucky," and the traditional Opry crowd, expecting straight bluegrass, gave him little more than polite applause. According to Opry lore, talent director Jim Denny told him afterward that he wasn’t going to make it as a singer and should go back to driving a truck. Elvis was so shaken that he reportedly cried the whole drive home to Memphis. He never performed at the Opry again. But two years later, "Heartbreak Hotel" hit number one, and Elvis Presley became one of the best-selling solo music artists in history, forever known as the King of Rock and Roll.

Thomas Edison

Thomas Edison struggled in the classroom. By the age of 12, he was partially deaf and easily distracted , and after only three months, in 1854, Nancy Edison, his mother, took charge of his education at home after a teacher sent him home with a note calling him "too difficult to teach." Much of his learning came at home through reading, experimenting, and satisfying his endless curiosity. As a young man, he also had trouble finding the right fit in the working world. Popular accounts say he was fired from two jobs because employers considered him unproductive. None of that matched what came next: Edison became an extraordinarily prolific inventor and eventually held 1,093 U.S. patents. His work included the phonograph, improvements to electric lighting, and motion-picture technology.

Lucille Ball

If you watched I Love Lucy , you know Lucille Ball was capable of turning a simple household mishap into complete comic chaos. But as a teenager, Ball was not yet the performer who commanded a room.

As a young woman, Lucille Ball enrolled at the Johnny Murray Anderson School for the Dramatic Arts in New York in 1926, at the age of 15, hoping to become an actress. Her instructors weren’t exactly encouraging. She was reportedly considered too shy and too timid for the stage and was advised to consider a different line of work entirely. She spent years afterward modeling and taking small, unremarkable film roles, far from stardom. Ball eventually found her footing not in dramatic film but in comedy and television, where her fearless physical humor became her signature. In 1951, she co-created and starred in I Love Lucy with then-husband Desi Arnaz, and it became one of the most successful sitcoms in television history.

Henry Ford

Buying a new car today can make it easy to forget how experimental the automobile business once was. Around the turn of the 20th century, companies started and collapsed, and Henry Ford was one of those business owners who had to reinvent himself more than once.

Ford’s first venture, the Detroit Automobile Company, launched in 1899 and folded within two years , undone by vehicles that were too expensive and too slow to build. His backers pushed him out. He tried again with the Henry Ford Company, but it ended the same way, with investors losing patience and Ford losing control of the business bearing his own name. By 1902, he had two failed automakers behind him and no company at all. For the third time, in 1903, Ford started again. This time, he focused on building one dependable, affordable car and figuring out how to produce it faster than anyone thought possible. That car was the Model T, and the assembly line method he built around it didn’t just save Ford Motor Company; it changed how the entire world manufactures goods.

Martin Luther King Jr.

It’s weird to think that one of history’s greatest orators struggled in a classroom. But that’s exactly where Martin Luther King Jr.’s path began.

As a first-year student at Crozer Theological Seminary in the late 1940s, King took a course in public speaking and received a grade of C , a modest mark for a young man who hadn’t yet found his voice. He kept working at it throughout seminary, refining the cadence and clarity that would later define his preaching. Within a decade, that same voice was leading the Montgomery bus boycott and delivering the "I Have a Dream" speech to hundreds of thousands of people at the March on Washington in 1963, becoming one of the most recognized voices of the 20th century.

7

Oprah Winfrey

Considering how controlled news anchors’ expressions used to be, Oprah Winfrey’s early career sounds almost like a casting mistake.

In 1976, a 22-year-old Winfrey moved to Baltimore to co-anchor the evening news at WJZ-TV. The fit was rocky from the start. Her delivery was warmer and more emotional than the traditional hard-news style the format called for, and station management eventually pulled her off the anchor desk, with one producer reportedly calling her unfit for television news. It could’ve ended her career in broadcasting entirely. Instead, WJZ moved her to a struggling daytime talk show called People Are Talking . There, freed from reading headlines in a flat, detached tone, Oprah’s natural warmth turned into her greatest asset. The local talk show became the blueprint for The Oprah Winfrey Show , which ran for 25 years and made her one of the most influential media figures in American history.

8

Colonel Harland Sanders

Imagine reaching 65 and deciding that instead of settling into retirement, it’s time to travel around the country trying to convince restaurant owners to serve a recipe. Harland Sanders made exactly that decision.

By his mid-sixties, Sanders had lived through a string of failed jobs and businesses , and the small Kentucky restaurant where he’d perfected his fried chicken recipe closed after a new highway diverted its traffic away. Broke and living on a modest Social Security check, he decided to take his recipe on the road, driving from restaurant to restaurant and offering to share it in exchange for a small cut of sales. As the legend goes, he heard "no" more than a thousand times before a restaurant in Utah finally said yes in 1952. That handshake deal became the first Kentucky Fried Chicken franchise. Within a decade, hundreds of KFC restaurants dotted the country, and the white-suited Colonel Sanders (who died in 1980 at age 90) became one of the most recognizable faces in American food.

Stephen King

You’ve probably read Carrie , or watched It , but before he became a household name in modern terror, Stephen King was a young writer trying to get his work published.

In the early 1970s, King was teaching high school in his home state of Maine and writing in his spare time, often in a trailer with his wife and young kids nearby. He wrote a novel about a bullied teenage girl with telekinetic powers, but after around 30 rejection letters from publishers, he gave up on it and threw the manuscript in the trash . His wife, Tabitha, fished the pages back out and encouraged him to finish it, believing in the book even when he didn’t. That story became Carrie , published in 1974. It launched King’s career and eventually sold millions of copies, kicking off a body of work that would make him one of the most successful and prolific authors in American history.

Dr. Seuss (Theodor Geisel)

You may think publishing more than 50 books was easy for Dr. Seuss. But back when he was known as Theodor Geisel, his work got rejected dozens of times.

In the 1930s, Geisel wrote and illustrated a whimsical children’s book called And to Think That I Saw It on Mulberry Street. Publisher after publisher turned it down, reportedly around 27 of them, saying it was too different from anything else on the market. As the story goes, Geisel was walking down a New York street, manuscript in hand and ready to give up, when he ran into an old college acquaintance who happened to work at a publishing house and offered to take a look. That chance meeting led to the book’s publication in 1937. It launched Dr. Seuss’s career, which would go on to include classics like The Cat in the Hat and Green Eggs and Ham , beloved by generations of kids and their grandparents alike.

Frederick Smith (FedEx)

Today, overnight shipping is so ordinary that a package arriving the next morning (if not on the same day) barely raises an eyebrow. In the 1960s, reliably moving urgent packages overnight across the country was a very different proposition.

In 1965, as an undergraduate at Yale, Smith wrote an economics term paper describing a delivery service that would route urgent packages through one central hub by plane rather than relying on passenger airlines. His professor wasn’t convinced the idea was practical and marked the paper with a C. Smith went on to serve in the Marine Corps in Vietnam, but the idea from that paper never left him. In 1971, he founded Federal Express, built exactly around the hub-and-spoke concept he’d once sketched out for a grade. FedEx now moves millions of packages a day across the globe, and Smith spent the rest of his life running the company he first imagined as a 21-year-old college student.

What are bills made of?

Unlike other currencies, dollar bills are not made of paper or plastic. U.S. dollar bills are made from a special fabric blend composed of 75% cotton and 25% linen. This mix makes the bills extremely durable and resistant, and they can be folded about 4000 times before tearing.

2

What bills are valid?

Any U.S. dollar bill that was legally printed is valid, no matter how old, as American currency does not have an expiration date. While some bills might not be accepted by businesses of foreign exchange services due to their condition or if they are a discontinued version of the bill, the bills themselves are still valid, and American banks will accept them, though they might take them out of circulation.

3

American leaders

Five bills have a depiction of an American president. The exceptions are the $10 bill, with Alexander Hamilton on the front, and the $100 bill, with Benjamin Franklin. The $1 bill, depicting George Washington, is extremely symbolic: several elements are repeated 13 times as a nod to the thirteen colonies, and it showcases the Bald Eagle and the Eye of Providence as a sign of God watching over America.

4

A change in size

Did you know that dollar bills used to be so big that they were nicknamed "horse blankets"? Original dollar bills were 7.4 × 3.1 inches. In 1929, the Treasury Department reduced the size of bills to 6.14 × 2.61 inches to reduce production costs and materials. Old bills, though still valid, are worth much more as collector items.

5

Uniformity

Besides their value and design, all dollar bills have the same size (6.14 × 2.61 inches), color, and weight (1 gram) , which sets American currency apart from other countries where bills of different values are differentiated by size, color, or both. Why doesn’t the U.S. implement differences among bills? The cost of adapting vending machines, bank drawers, and ATMs to new bill sizes would cost billions of dollars.

6

Hard to copy

Originally, dollars were not green, but black. As time passed, green ink was favored, as it was cheap and did not fade as much as black. The new color also prevented people from using black-and-white cameras to create counterfeit money. Currently, dollar bills are predominantly green, but newer versions also include extra colors, such as pink, orange, or purple.

7

A $100,000 bill?

Have you ever seen a $500 or 1,000 dollar bill? What about a $100,000? Up until 1945, the U.S. Treasury printed $500, $1,000, $5,000, $10,000, and $100,000 notes , in addition to the values currently in use. These higher-value notes were mainly intended for bank and government use, but were sought by criminals as they made it easier to hide large amounts of money. Even though they were officially discontinued in 1969, these notes are still valid, though rare, and they have a high worth as collector's items.

8

No numbers

Unlike bills, American coins have different sizes and colors related to their value. Originally, gold, silver, and copper were used for coins, but modern coins are made of copper, zinc, or nickel. Besides their size and design, the value of each coin is printed in letters, not in numbers , alongside depictions of American presidents.

9

Liberty for all (the coins)

By law, all American coins must include six specific details : the word ‘Liberty’, the name of our country, the national motto "In God We Trust", the oldest American motto "E Pluribus Unum", the value of the coin, and the year. Each coin also includes a mint mark that shows where it was made: "P" for Philadelphia, "D" for Denver, "S" for San Francisco, and "W" for West Point.

10

A global currency

The American dollar is one of the most powerful currencies in the world, acting as a backbone for international trade and finances. It is estimated that two-thirds of the physical dollars in circulation are outside American territory. Besides the U.S. and its territories, eight sovereign nations have the U.S. dollar as their official currency, with several more accepting it as legal tender.

There's an unexplained billion-year gap

Look closely at the canyon walls, and you'll notice something strange: a clean, sharp line where ancient rock simply stops, and a much younger layer begins directly above it.

This geological puzzle is called the "Great Unconformity," and it represents over a billion years of rock layers that are simply absent , as though that stretch of time never happened. In some spots, rock dated 1.8 billion years old sits directly beneath rock that is only 520 million years old. Where did the missing billion years go?

The leading theory involves the violent breakup of an ancient supercontinent, but scientists are still piecing it together.

2

During the Cold War, it hid a nuclear fallout shelter

During the Cuban Missile Crisis in 1962, the U.S. government converted part of the Grand Canyon Caverns into a fallout shelter. This dry cave system, more than 200 feet underground, was stocked with enough food and water to sustain 2,000 people. Naturally, it was never occupied, and the supplies were never used.

The caverns have since been transformed into a tourist attraction, with organized tours winding through the same underground chambers that were once intended as a refuge from nuclear war. You can even book a night's stay there.

3

The Federal Aviation Administration was founded after a crash over the canyon

In 1956, two commercial passenger planes collided in midair over the eastern Grand Canyon, killing all 128 people on board both crafts. Rescue teams struggled to reach the wreckage deep inside the canyon, and the extreme heat of the crash had caused the planes' aluminum to fuse with the bedrock. There were no survivors.

The disaster exposed a terrifying truth: the U.S. air traffic control system was dangerously outdated, relying on pilots' visual estimates and rough guesswork from controllers , with no way to separate fast-moving aircraft from slow ones, or instrument-flying planes from those navigating by sight. Congress responded by passing legislation that created both the Federal Aviation Administration (FAA) and the National Transportation Safety Board.

4

A hoax suggested that an Egyptian civilization had lived there

In 1909, the Arizona Gazette reported that an explorer named G. E. Kinkaid had discovered a vast underground citadel inside the canyon, filled with artifacts linked to ancient Egyptian civilization. He even claimed the expedition had been funded by the Smithsonian.

This story described hieroglyphics on the walls, mummies in the chambers, and relics pointing to a direct connection with the Egypt of the pharaohs. It was incredibly detailed, and it was, of course, a hoax. No evidence for any of Kinkaid's claims ever surfaced.

5

Fewer than 100 people have ever hiked its full length

Among the few people who have completed the through-hike of the Grand Canyon is Jen Hogan, the first woman to accomplish it, finishing her journey in 2021–2022.

It’s a full 800-mile length below the rim. The route involves extreme heat, flash floods, near-impassable areas, and stretches with no water or trail whatsoever. Around 60 or 70 people have reportedly accomplished it. This makes it one of the most exclusive feats on Earth.

6

The Grand Canyon's rocks predate dinosaurs entirely

Visitors scanning the canyon walls for fossils are often surprised to learn they won't find any dinosaur bones here. The rock layers of the Grand Canyon are simply older than dinosaurs. This fact alone can be shocking: staring at its walls means staring at marine fossils from as far back as 1.2 billion years ago. Some of its caves hold the remains of ancient mammals. The canyon is a window into a world that existed long before the dinosaurs, when the land that is now Arizona lay beneath a shallow sea.

7

The park is bigger than Rhode Island

Numbers alone rarely capture the Grand Canyon's scale, so here's a different approach. Rhode Island covers about 1,214 square miles, and the Grand Canyon National Park spans 1,904 square miles.

The canyon's depth exceeds four Empire State Buildings (which is 1,454 feet) stacked on top of one another. That’s 6,093 feet at its deepest point.

8

But it's not the deepest canyon on Earth

For all its grandeur, the Grand Canyon does not hold the depth record. Pictured above, the Yarlung Tsangpo Grand Canyon in Tibet, China, plunges to 17,567 feet, which is nearly three times deeper. Carved by the Yarlung Tsangpo River as it cuts through the eastern Himalayas, that canyon is so remote and extreme that it remained largely uncharted until the late 20th century.

9

It is home to a pink rattlesnake found nowhere else on Earth

The Grand Canyon Pink Rattlesnake has a pinkish-red coloring that matches the canyon's own distinctive rock walls so closely that it's nearly invisible. It is found nowhere else in the world. Officially classified as Crotalus oreganus abyssus , it has darker diamond-shaped markings along its back that deepen the camouflage further.

10

There's a village at the bottom: Supai Village

For over 1,000 years, the remote village of Supai has been home to the Havasupai Tribe, the People of the Blue-Green Waters. It is located an eight-mile hike from the rim, but sits roughly 3,000 feet deep inside the Grand Canyon.

The U.S. Department of Agriculture has called it the most remote community in the contiguous United States, and it has no automobiles and no road access. The only ways in are on foot, by mule, or by helicopter. It is also the only place in the United States where the postal service still delivers mail by mule train.
