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.

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.

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.

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.

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.

"Jolene" by Dolly Parton

One of Dolly Parton’s most famous songs, 1973’s "Jolene," has resonated across generations because its story of jealousy feels so relatable. And it was inspired by a real experience in Dolly’s life.

As she recounted in interviews, the song was inspired by an attractive female bank teller who paid a little too much attention to her husband, Carl Dean. But while the jealousy was real, the woman wasn’t named Jolene. Dolly got that name from a young fan with beautiful red hair and green eyes who introduced herself to the singer after a concert.

"Sweet Caroline" by Neil Diamond

Neil Diamond wrote "Sweet Caroline" in 1969, drawing on his feelings for his wife at the time, Marcia Murphey. But if it was about her, why "Caroline"?

Diamond needed a three-syllable name for the lyrics, and he remembered a photo of First Daughter Caroline Kennedy with her horse that he had seen in LIFE magazine in 1962. Diamond kept the connection to JFK’s eldest secret for nearly 40 years until 2007, when he sang the hit for Caroline at her 50th birthday and finally told her the story. She was "struck by it and really, really happy," Diamond revealed.

"You're So Vain" by Carly Simon

When a relationship ends, the inspiration can show up in unexpected ways. For Carly Simon, it became one of her biggest hits: "You’re So Vain."

As Simon herself confirmed, most of the lyrics were inspired by actor Warren Beatty, with whom she had a brief but intense relationship in the early 1970s that ended after he cheated on her. But Beatty wasn’t the only "vain" one. Although she didn’t confirm it, there’s speculation that other famous men from her past, including Mick Jagger and Jack Nicholson, also inspired parts of the song.

"I Will Always Love You" by Dolly Parton

Despite what many assume, "I Will Always Love You" wasn’t written about a romantic breakup. Dolly wrote it as a professional farewell .

After more than seven years working with her mentor and longtime duet partner, Porter Wagoner, on The Porter Wagoner Show , Dolly felt it was time to pursue a solo career. But the decision wasn’t easy, and Wagoner was reluctant to let her go. When ordinary conversations weren’t working between them, Dolly did what she knew best: she put her feelings into a song. She brought her guitar to his office, sat him down, and played it for him. Wagoner was moved to tears, called it the prettiest song he had ever heard, and finally agreed to let her leave the show.

"American Pie" by Don McLean

A song can be a farewell, a declaration of love, or a tribute born of admiration. That was the case when Don McLean wrote the beautiful yet haunting "American Pie" in 1971.

This epic folk-rock song became a memorial to "the day the music died," the tragic plane crash on February 3, 1959, that took the lives of rockers Buddy Holly, Ritchie Valens, and J.P. Richardson . McLean was just 13 at the time, but he later said the tragedy had a profound impact on him. The song didn’t come together all at once, either; he wrote it in stages over several years.

"Billie Jean" by Michael Jackson

In his 1988 autobiography Moonwalk , Jackson explained that his classic "Billie Jean" was inspired partly by experiences involving women who approached his older brothers while the Jackson 5 were touring.

However, the event that really shaped the song happened in 1981, when Jackson received thousands of messages from a woman who claimed he was the father of her children. The unsettling situation stayed with him and eventually became part of the inspiration for one of his biggest hits.

"My Sharona" by The Knack

Have you ever wondered who "Sharona" was in The Knack’s famous hit? The answer comes from a real story involving the band’s lead singer, Doug Fieger.

In 1978, Fieger met Sharona Alperin, a clothing store clerk in Los Angeles. He was instantly attracted to her, and after breaking up with his then-girlfriend, he spent several months trying to win Sharona over before she finally agreed to a date. Their romance lasted from 1979 to 1982, and inspired one of the most danceable hits of the 20th century. Even after they broke up, Sharona and Doug remained close friends until he passed in 2010.

"Sweet Child O' Mine" by Guns N' Roses

In 1986, Axl Rose was dating model Erin Everly, daughter of Don Everly of The Everly Brothers. He was so in love that he wrote her a love poem in just a few hours, without knowing it would eventually become one of his most famous songs.

That same year, at the band’s shared house, guitarist Slash was playing around with some chords when he came up with an interesting riff. Izzy Stradlin joined in, and when Rose heard the melody from upstairs, he brought down the poem he had written for Everly and adapted the lyrics to fit the music, resulting in the iconic "Sweet Child o’ Mine." Rose and Everly eventually married in 1990, but the marriage ended soon afterward.

"Walk On the Wild Side" by Lou Reed

Music crossed paths with other forms of art when Lou Reed wrote his 1972 classic "Walk on the Wild Side".

The song is essentially a series of portraits of real people from Andy Warhol’s circle at The Factory, his famous New York City studio and collective. In the song, "Holly" is a reference to Holly Woodlawn, a transgender actress who appeared in Warhol’s underground films such as Trash (1970). "Candy" was Candy Darling, another prominent actress who starred in Flesh (1968) and Women in Revolt (1971). "Little Joe" referred to Joe Dallesandro, the actor and model who became one of Warhol’s male muses. Other figures from the era’s counterculture are also in the song, bringing a very specific art scene of 1970s New York to a much wider audience.

"Sara" by Bob Dylan

In 1975, Bob Dylan was in the middle of a creative rush, writing and recording his album Desire . But while his career was going well, his marriage to Sara Lownds was falling apart. So he decided to write a love song for his wife.

"Sara," a heartfelt and personal song, was recorded in 1975 with Sara in the studio, and it became the raw, emotional closing track on the album. It helped spark a brief reconciliation, and Sara even joined Dylan on his subsequent Rolling Thunder Revue tour. However, the marriage ultimately ended in divorce in 1977.

Network executives thought Desi Arnaz was "too foreign" for TV

Network executives initially hesitated to cast Desi Arnaz as Ricky Ricardo, Lucille Ball’s husband on I Love Lucy (which aired on CBS from 1951 to 1957) because they doubted that viewers would accept an American woman and a Cuban man as a believable suburban pair.

To prove the concept worked, Ball and Arnaz took a live vaudeville act on the road in 1951, receiving overwhelmingly positive feedback from audiences. The public's reaction helped persuade CBS to give the show a chance with Arnaz in the starring role. And as we all know, the couple was married in real life too and eventually had two children: Lucie, born in 1951, and Desi Jr., born in 1953. It doesn’t get more "real" than that.

2

The word "pregnant" was strictly forbidden on air

On the show, CBS banned the word "pregnant" in 1952, considering it too explicit for family living rooms . Writers therefore relied on euphemisms such as "expecting," "with child," or "having a baby."

When Lucille Ball became pregnant with her second child in 1952, Desi Arnaz pushed for her pregnancy to be written into the show's storyline, despite initial resistance from CBS and its sponsors. The resulting plot became a landmark moment in television history: although the show could portray Lucy expecting a baby, its writers still couldn't use the forbidden word. That’s why the episode in which she breaks the news to Ricky was titled "Lucy Is Enceinte," using the French word for pregnant.

More people watched Lucy give birth than the president’s inauguration

On January 19, 1953, the episode "Lucy Goes to the Hospital", in which she gives birth to Little Ricky, drew an estimated 44 million viewers (about 72% of U.S. television households). In an extraordinary coincidence, Ball gave birth to her real-life son, Desi Arnaz Jr., by scheduled cesarean section on the same day.

The next day, President Dwight D. Eisenhower’s inaugural address drew an estimated 29 million viewers. That means the episode attracted roughly 15 million more viewers than the president's address, according to the commonly cited estimates.

The candy factory episode had a real-life expert in it

In the beloved "Job Switching" episode, the Season 2 premiere which aired on September 15, 1952, Lucy and Ethel (Vivian Vance) take jobs at Kramer’s Kandy Kitchen to prove to their husbands, Ricky and Fred (William Frawley), that they can handle the demands of working outside the home.

Assigned to wrap and dip chocolates on an assembly line, the pair fall hopelessly behind as the conveyor belt speeds up. Desperate to avoid letting any unwrapped candy pass by, they begin stuffing chocolates into their mouths, hats, and blouses. The resulting chaos became one of television's most beloved comedy scenes. But here's a fun backstage detail: to prepare for the sequence, Ball and Vance spent half a day learning to dip chocolates and work on the production line at a real See's Candies location in Los Angeles. Even more interesting, the woman working alongside Lucy in the scene was an actual See's Candies candy maker, Hazel Pierce .

5

Fred and Ethel viscerally despised each other in real life

Playing married couple Fred and Ethel onscreen, Frawley and Vance clashed throughout the show's six-season run. Vance was 42 and Frawley was 64 when the show started. She reportedly resented being cast opposite a man 22 years older and famously complained: "How will anyone believe I’m married to that old man?" Frawley overheard her complaints and was reportedly offended. He later made this pointed remark about Vance, "She's one of the finest girls to come out of Kansas, but I often wish she'd go back there."

Despite their bitter off-screen feud, both remained professional on set and delivered the comedic chemistry that made Fred and Ethel such a memorable couple. Vance later reportedly turned down a lucrative spin-off featuring the pair, along with a $50,000 bonus, because she didn't want to work with Frawley again.

Desi Arnaz’s deal that changed TV reruns forever

Desi Arnaz’s production decisions helped establish reruns as a profitable part of the industry. He insisted that I Love Lucy be filmed rather than broadcast live, helping shape the modern sitcom format. In the early 1950s, television shows were preserved only as low-quality kinescopes, recordings made by filming television screens.

Ball and Arnaz wanted high-quality recordings, so they were shot on 35mm film using a three-camera setup in front of a live studio audience. As part of their landmark deal with CBS, their production company, Desilu Productions, retained ownership of the film negatives, allowing the episodes to be rebroadcast. By 1955, I Love Lucy had become the first television series to be broadcast as reruns , helping pave the way for modern syndication.

7

Ricky Ricardo was almost named "Larry Lopez"

During the development of I Love Lucy, Ricky Ricardo was initially called Larry Lopez, but the name was changed for two main reasons.

First, the producers wanted to avoid confusion with Vincent Lopez, a well-known bandleader of the era. Second, they reportedly preferred the sound of "Lucy and Ricky" to "Lucy and Larry," since it sounded overly alliterative.

8

Lucy was not a natural redhead

Lucille Ball wasn't a natural redhead. Instead, she was a brunette who kept her brown hair during her early career, and also experimented with blonde shades before adopting the fiery red look that became her trademark.

Around 1943, she famously went red for her role in the Technicolor musical Du Barry Was a Lady. MGM hairstylist Sydney Guilaroff helped create the look , which Ball later maintained with a custom blend of henna and dye. Ultimately, her signature color was a carefully crafted Hollywood style, not her natural shade. And it worked.

9

Desi Arnaz used cushions to appear taller than Lucy

Desi Arnaz reportedly wore Cuban heels or other elevated footwear to help him appear taller alongside Lucille Ball. Although he stood around 5 feet 9 inches tall and Ball about 5 feet 7 inches in her stocking feet, her high heels could make her look taller than him.

The production team reportedly used another trick when the couple sat down : specially arranged cushions on the Ricardos’ couch and chairs helped maintain the desired height difference on screen and made it easier for Arnaz to stand up.

10

Lucy’s mother left her mark on the show’s soundtrack

Lucille Ball's mother, DeDe Ball, was a devoted supporter who reportedly attended the filming of almost every episode. Whenever her daughter landed in a comically awkward situation, DeDe would let out a distinctive "Uh-oh!" from her seat in the studio audience.

Sound engineer Glen Glenn reportedly liked the exclamation so much that he recorded it and incorporated it into the show's laughter track . Because the same recording was reused, DeDe's distinctive voice became part of the show's familiar soundtrack. The story even suggests that her "Uh-oh!" may have made its way into the soundtracks of other classic sitcoms over the years.
