The Second of July?

The first 4th of July celebration took place spontaneously in Philadelphia in 1777 and included elements that still persist today, such as bonfires, parades, and fireworks. But not everyone was on board. Founding Father John Adams famously refused all invitations to celebrate on account of disagreeing with the date.

For him, celebrations needed to be held on July 2nd, the day independence was voted on, rather than the 4th, when independence was declared , but July 4th became widely accepted because it was the date that appeared on the distributed copies of the document. In a both poetic and ironic turn of events, Adams — along with Jefferson, who penned the document — died on July 4th, 1826, on the 50th anniversary of the Declaration of Independence.

Who came up with the turkey pardon?

While many correctly assume that the official Presidential turkey pardon on Thanksgiving is an old event, it was not an official tradition until 1989, under the George H.W. Bush administration . But the roots of the tradition are nearly as old as the holiday itself.

In 1863, President Abraham Lincoln’s young son, Tad, asked to adopt the turkey intended for the Christmas dinner and named it Jack. This didn't become a regular tradition, but it set the precedent for President Kennedy to pardon the turkey gifted to the First Family in 1963 , a custom adopted by many of the following presidents, with Reagan being the first to call it the "presidential pardoning".

The anti-pumpkin movement

As a crop native to America, pumpkin is mentioned across American history, including the first Thanksgiving. But before pumpkin pie was a symbol of the holiday, it was a New England dessert that divided the nation.

Thanksgiving was instituted as an official holiday by Abraham Lincoln in 1863, with turkey and pumpkin pie quickly becoming the main dishes on the menu. After the Civil War, the Southern states were reluctant to adopt the holiday and its associated pie, claiming it was a "Yankee tradition" and a celebration of Northern culture. As a way of rejecting what they saw as a cultural imposition, many Southern cooks replaced the pumpkin pie with sweet potato pie, which remains much more common in the South.

The 22 years without Christmas

The minute Thanksgiving ends and "All I Want for Christmas Is You" returns to the top of the charts, much of the country gets into the holiday spirit. Surprisingly, just a few centuries ago, and 100 years before the United States was officially formed, Christmas was banned altogether .

During Cromwell’s interregnum (1649-1660), the Puritan-led English Parliament canceled the Christmas festivities of 1644, claiming it was a Catholic festivity of pagan origin. The sentiment echoed across the Atlantic, where the Massachusetts Bay Colony, of Puritan origins, banned Christmas in 1659 and fined those who celebrated or took the day off. The ban remained in place even after the restoration of the Monarchy, and was only lifted in 1681. Ulysses S. Grant declared it a federal holiday in 1870.

Mandatory anonymity

Anyone who ever celebrated Mardi Gras in New Orleans knows that masks are an integral part of the event, with those in the parade and many spectators concealing their identity. What many don’t know is that, per Louisiana law, wearing a mask in public is illegal , a statute passed in the 1920s to counteract the Ku Klux Klan’s influence and its intimidation tactics.

So, what happens during Mardi Gras? In the traditional Carnivals, masks were a way for people of all classes to mingle without endangering their reputation. While it is not a requirement for spectators today, anti-mask laws are suspended during Mardi Gras . However, if you are taking part in the parade, masks are not only allowed but mandatory.

A very successful campaign

Does your family watch the Rose Bowl Game on January 1st? It’s one of the oldest postseason football games in American history . But, did you know that its origin stems from a tourism campaign?

In the 1890s, the city of Pasadena, California, started celebrating the Tournament of Roses Parade on New Year’s Day as a way to promote the city’s mild weather to tourists on the East Coast . To increase promotion, a postseason college football game was played in 1902, but the result was so lopsided —49-0— that it was not repeated the following years. In 1916, a new game was organized with resounding success, and it has been held annually since then.

The original Black Friday

B efore being synonymous with big sales and discounts, Black Friday was synonymous with crisis . The first recorded use of ‘Black Friday’ dates back to 1869, when the stock market suffered a devastating crash due to financial speculation. The economic effects of the crash were so severe that the name connoted calamity and misery.

How did it become associated with the day after Thanksgiving? In the 1950s, Philadelphia received hordes of tourists who came to shop and attend the annual Army-Navy football game the day after Thanksgiving, creating such chaos that the police forces dubbed it the "Black Friday". To counteract the negativity, retailers adopted the name in association with massive discounts.

From Decoration to Memorial Day

The last Monday of May, America remembers and honors those who laid down their lives in defense of the country. Friends and relatives of fallen service members gather to lay wreaths and flags in cemeteries ; the Memorial Day holiday also serves as the unofficial starting point for the summer season. But where does this tradition come from?

It wasn’t always Memorial Day. Originally called ‘Decoration Day’, the tradition of adorning graves started after the Civil War , and it was first celebrated on a national scale in 1868. After World War I, the tradition was expanded to include all American soldiers fallen during a military conflict.

Hedgehog Day

You might just know about it because of the popular 1993 Bill Murray movie, but Groundhog Day is real, and it’s celebrated every February 2nd. According to tradition, if a groundhog emerging from its burrow sees its shadow, it will go back to hibernate , and there will be six more weeks of winter. If not, spring will come early. But did you know that the tradition usually observed the behavior of a different animal?

Though Groundhog Day is celebrated across America —and even Canada— it was initially a Pennsylvania tradition, brought by German and Dutch immigrants. Back in Europe, they observed the behavior of hedgehogs and badgers to predict the length of winter, but these were not native to America. Looking for a similar local animal, they turned to the groundhog.

The 6-month difference

We can name a select few holidays that are celebrated internationally, such as New Year’s Day or Christmas. But what about Labor Day? While nearly 160 countries across the globe celebrate it on May 1st, the U.S. celebrates it six months later , on the first Monday in September.

Labor Day (also known as International Workers’ Day) started as a commemoration of the 1886 Haymarket Affair in Chicago, where a protest for workers’ rights ended with several casualties. As the protest was linked to socialist labor movements, the U.S. government was wary of celebrating workers on that date . As a compromise with labor activists, President Grover Cleveland instituted Labor Day as a federal holiday in 1894, but deliberately chose a date as far away as possible.

He served hot dogs to British Royalty

In 1939, for the first time ever, a sitting US president hosted the reigning British monarchs on American soil. And it wasn’t just a formal state meeting; it was a picnic.

On June 11 of that year, President Franklin D. Roosevelt and First Lady Eleanor Roosevelt welcomed King George VI and Queen Elizabeth to their home in Hyde Park, New York. Instead of an elaborate diplomatic banquet, the menu was unexpectedly simple and quintessentially American: hot dogs and beer. According to FDR, the queen politely tried hers with a knife and fork, while the king ate several with his hands and seemed to enjoy them. Behind the scenes, the visit was more than symbolic, yet folksy hospitality. With war already looming in Europe, both sides were quietly strengthening ties that would soon become crucial during WWII.

The first sitting president to fly on a plane

While FDR made history in many ways, one of his lesser-known firsts took place thousands of feet above the ground.

On January 11, 1943, in the middle of WWII, he became the first sitting US president to fly in an airplane. At a time when air travel was still far from routine, he embarked on a secret 7,000-mile journey from Miami, Florida, to Bathurst, Gambia, before continuing to Casablanca, Morocco. The trip wasn't taken for leisure; German U-boats had made Atlantic sea travel risky, so Roosevelt crossed the ocean aboard a Boeing 314 flying boat known as the Dixie Clipper . His destination was the Casablanca Conference, where he met with British Prime Minister Winston Churchill to discuss wartime strategy.

Highly superstitious

Are you the type to knock on wood to avoid bad luck? Or would you walk under a ladder without a second thought? If you're in the first group, you would have fit right in with Franklin D. Roosevelt.

FDR famously declared that "the only thing we have to fear is fear itself," but he also had a surprisingly superstitious side. According to people who worked with him in the White House, Roosevelt kept his desk and personal items arranged in a precise order that he believed brought good luck. He also disliked the number 13: family members and aides recalled that he avoided hosting dinners with 13 guests and was reluctant to begin important trips on Friday the 13th. He even had a lucky charm, a brown felt fedora that he wore during all four of his presidential campaigns. We can't say it didn't work.

4

He loved practical jokes

With all his responsibilities, talents, and interests, FDR still found time to joke around.

According to his biographers, Roosevelt loved practical jokes and kept his playful streak throughout his life, even pulling pranks well into his presidency. In the tense world of politics, that sense of humor became one of his trademarks. He enjoyed classic gags, including putting bubbling powder in drinking glasses to surprise White House guests, or slipping completely made-up words into conversations and then watching with delight as his staff scrambled to check the dictionary. Friends and aides also noted that he had a unique ability to laugh off rumors, criticism, and political attacks that might have rattled other leaders.

5

Peculiar work schedules

Jokes didn't distract FDR from his work. If anything, they helped him cope, and he certainly had plenty of work to do. In fact, Roosevelt was known for his unusual working hours.

Unlike many other presidents who were early risers, he often worked late into the night and typically didn't begin his day until around 9 am. During WWII, while overseeing a global conflict, he regularly spent his evenings reviewing reports, making decisions, and meeting with advisers long after most Americans had gone to bed. What makes this even more impressive is that he maintained this pace as his health steadily declined. Doctors urged him to slow down and limit his workload, but Roosevelt frequently ignored that advice. For a wartime commander-in-chief, there was always one more decision to make.

6

He appointed the first female cabinet member

Among his many historic firsts, FDR was the inaugural POTUS to appoint a woman to a Cabinet position, a decision that reflected both his political instincts and his willingness to recognize talent and intelligence where he found it.

In 1933, he chose labor advocate Frances Perkins as Secretary of Labor. It turned out to be one of the most consequential appointments of his presidency. Perkins served from 1933 to 1945, making her the longest-serving Secretary of Labor in American history. And as if that weren't enough, she became one of the chief designers of the New Deal.

11 presidential relatives

Most people know that Franklin D. Roosevelt and Theodore Roosevelt were related: the 32nd president was a distant cousin of the 26th. But few realize just how extensive FDR’s presidential family tree really was.

In fact, genealogists have traced Franklin Roosevelt’s family connections to at least 11 US presidents. FDR was not only related to Theodore Roosevelt and his own wife, Eleanor Roosevelt (his fifth cousin once removed), but also to an impressive number of other commanders in chief. Among those connected to him by blood were George Washington (with whom he shared ancestors from English nobility and the early settlers of Virginia), John Adams, John Quincy Adams, James Madison, and William Harrison. Through marriage and extended family ties, he was also related to Ulysses S. Grant, Benjamin Harrison, Zachary Taylor, Martin Van Buren, and William Howard Taft.

8

His illness may not have been polio

As is well known, FDR was struck by a serious illness in 1921 at age 39 that left him permanently unable to walk unaided. But during his presidency, he worked hard to keep public attention focused on his leadership rather than on his body, so while Americans understood he had been diagnosed with polio, few knew about the paralysis.

To stand at public events, Roosevelt relied on heavy steel leg braces and canes that helped him project confidence and strength throughout his presidency. However, although doctors at the time diagnosed him with polio, some modern medical researchers have suggested that his symptoms may have been more consistent with Guillain-Barré syndrome (GBS), a rare autoimmune disorder.

9

He didn’t graduate from law school

FDR was a bright and curious man who threw himself into subjects that fascinated him, but when something failed to hold his interest, he wasn't afraid to move on.

After earning a History degree from Harvard University in 1903, he enrolled at Columbia Law School, but he found that he simply didn't enjoy it. According to the Miller Center at the University of Virginia, Roosevelt showed little enthusiasm for the legal profession, and maybe that’s why he never achieved a Law degree. Even so, he passed the New York bar exam and began practicing after it, but the experiment lasted only a few years. Then, in 1910, an opportunity came along that interested him far more: local Democrats in New York asked him to run for the state Senate. Roosevelt eagerly accepted, and his political career was underway.

10

Expert in many fields

Politics and wartime strategy weren't FDR's only talents. Long before he entered the White House, he acquired a deep interest in nature.

Growing up in Dutchess County, New York, Roosevelt developed a fascination with birds that went far beyond a childhood hobby. By age 11, he was already learning taxidermy, eventually becoming a skilled self-taught naturalist and bird expert. Over the years, he identified and cataloged roughly 300 bird species. His detailed field journals and collection of more than 300 Dutchess County specimens are still considered some of the most complete records of local bird life from that era.

It was invented in Switzerland

While the name suggests a US origin, the technology that created American cheese actually began in the heart of the Alps. It was developed in 1911 by Swiss researchers Walter Gerber and Fritz Stettler, who were looking for a way to extend the shelf life of their country’s famous Emmental cheese.

The problem with traditional cheese is that it eventually dries out, molds, or separates into a greasy mess when heated. By shredding the cheese, adding sodium citrate, and heating it, the Swiss duo discovered they could create a stable, smooth product that didn't separate. While they weren't trying to create "American" cheese as we know it today, their emulsification process laid the foundational science for every single-wrapped slice produced today.

2

It was popularized by a Canadian

The man responsible for the global dominance of American cheese was James L. Kraft. Ring any bells? Kraft was a Canadian immigrant who moved to Chicago in 1903. While he didn't invent the concept of processed cheese, he perfected the industrial scale of its production and marketing.

Kraft noticed that retailers struggled with cheese spoilage; if a wheel of cheddar didn't sell quickly, it was a total loss. He experimented with various methods of heating and blending cheese until he found a formula that could be canned and shipped long distances without spoiling. In 1916, he received a patent for his "processed cheese," and during World War I, the U.S. government purchased millions of pounds of it for soldiers, cementing its privileged place in the American diet.

3

It was almost called "Embalmed Cheese"

When processed cheese first hit the market, it had its detractors. Traditional cheesemakers were horrified, and so were pure food advocates. These critics argued that the product shouldn't even be called cheese. They’ve even gone so far as to call it "embalmed cheese" because of its unnaturally long shelf life and the chemical emulsifiers used to keep it stable. Yet, Kraft’s marketing prowess and the sheer convenience of the product ultimately won the naming battle. At least in the court of public opinion.

4

Technically, it isn’t cheese

Kraft may have won the battle among the people, but legally, American cheese is not considered cheese. If you look closely at the packaging, you will rarely see the word "cheese" on its own. Because of strict FDA regulations, most varieties are legally classified as "Pasteurized Process Cheese Product" or "Pasteurized Process American Cheese Food."

To be labeled "cheese," a product must be made primarily of milk, salt, and enzymes. Processed American cheese, however, is made by blending real cheese—usually cheddar or Colby—with emulsifying salts, whey, and sometimes extra milk or fats.

5

Any cheese can be made into American cheese

The term "American cheese" refers more to a process than a specific flavor. In theory, you could make "American-style" brie, blue cheese, or parmesan. The defining characteristic is the addition of an emulsifier, which breaks down the proteins and allows the fats and water to stay together.

In fact, some high-end chefs now make their own artisanal American cheese with aged cheddars processed with sodium citrate to create a slice that has the complex flavor of an expensive block but the melting point of a Kraft Single.

6

It isn’t naturally yellow

The vibrant orange-yellow hue of American cheese is entirely a cosmetic choice. Traditionally, cheese color varied by the season; when cows ate fresh grass in the summer, their milk contained more beta-carotene, leading to a naturally yellowish cheese. To make their cheese look high-quality all year round, cheesemakers began adding dyes.

American cheese takes this tradition to the extreme. It is typically colored with annatto, a seed from the achiote tree. Without this dye, American cheese would be a pale, creamy white, which is how it is sold in many delis as "White American". Yes, that’s right, there is no flavor difference between the white and yellow versions.

7

It has an extremely low melting point

The scientific superpower of American cheese is its meltability. Traditional cheeses have a protein structure that tightens when heated, which is why a slice of aged cheddar on a burger often results in an oily puddle and a rubbery clump.

Because of the emulsifying salts, the proteins in American cheese can withstand heat without clumping together. This gives it an incredibly low and stable melting point, transforming the slice into a silky sauce. This is why it remains the undisputed king of grilled cheese sandwiches.

8

It’s been in space

When you're hurtling through orbit in a cramped capsule, you need food that is stable, easy to eat, and won't crumble into thousands of tiny, electronics-clogging pieces. American cheese fit the bill perfectly for early NASA missions.

Processed cheese in tubes or cubes was a staple of the Apollo missions. Because it doesn't separate or sweat oil in varying temperatures and pressures, it was one of the few dairy products that could reliably provide flavor and calcium to astronauts.

9

It helped bring cheese to the masses

Before the advent of processed cheese, cheese was often a seasonal luxury. It was difficult to transport, expensive to store, and highly variable in quality. James L. Kraft’s invention changed that. By creating a product that was uniform in flavor and shelf-stable, he made cheese affordable and accessible to every corner of the United States.

10

The U.S. Government once gave it out

The U.S. government not only bought tons of American cheese during World War I. In the 1980s, the term "government cheese" became a thing. During a period of dairy surpluses, the government bought millions of pounds of cheese to prop up prices for struggling farmers.

To avoid letting it rot, the Reagan administration began distributing five-pound blocks of cheese to low-income families, seniors, and schools. For many who grew up in that era, that pale orange processed cheese was a lifesaver.
