Locomotive steam-engine for rail (Patent #1)

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

Between 1790 and 1836, the United States granted 9,802 patents that were not awarded on their merits and didn’t have an identification number. The Patent Act of 1836, which established the official Patent Office, aimed to make the system more transparent. Among other reforms, it introduced a numbering system for easier identification.

This system started on July 13, 1836, and remains in effect today. United States Patent No. 1 was issued to John Ruggles —an inventor, attorney, and senator from Maine—for improvements in locomotive traction.

Anesthesia (Patent #4,848)

Image: National Library of Medicine

How did patients endure surgery before anesthesia? Before the discovery of an effective anesthetic, surgery was synonymous with excruciating pain. Many large hospitals placed their operating rooms in isolated and remote sections of the hospitals so patients’ screams couldn’t be heard. Alcohol, opium, and even hypnotism were tried as methods of pain relief, but these had little effect.

Fortunately, we no longer have to endure such experiences, thanks to a Boston dentist named William T. G. Morton, who—along with Charles T. Jackson—received the first United States patent for an anesthetic in November 1846.

This may be the most unique patent ever issued by the United States Patent Office: it is the first and only U.S. patent granted to an inventor who later became president. Although at least three presidents—George Washington, Thomas Jefferson, and Abraham Lincoln—were inventors, Lincoln is the only one who formally applied for and received a patent .

In 1849, he was awarded Patent No. 6,469 for a flotation device designed to lift boats over shoals and other obstacles in the water. While the invention itself had little bearing on his election, Lincoln’s inventive mindset and mechanical curiosity served him well during his presidency. Although the device was never commercially produced, his appreciation for innovation helped shape the nation's future.

Beekeeping arrived in America with the early settlers, and by the end of the 18th century, bee colonies were widespread. However, early efforts met with only partial success.

The first U.S. patent for a practical and effective movable-frame beehive—which revolutionized traditional methods of beekeeping—was granted to American apiarist, clergyman, and teacher Lorenzo Lorraine Langstroth on October 5, 1852. His invention of the "bee space" laid the foundation for all modern beekeeping and hive management.

Elevator (Patent #31,128)

The New York skyline would look very different today had it not been for the invention of the elevator. The man responsible for the forerunner of the modern elevator was American industrialist Elisha Graves Otis , who, on January 15, 1861, received the first U.S. patent for a safety-type passenger elevator.

The concept of vertical travel was not new. However, the first successful passenger safety elevator was installed in 1857 by Otis in the E. V. Haughwout & Company building, a department store in Manhattan. Otis also held patents for other inventions, including railroad trucks and brakes, a steam plow, and a bake oven. But it was the elevator with its safety feature that brought him fame and his sons great fortune.

Lock (Patent #31,278)

The idea of the lock probably stems from the time man first acquired goods he wanted to safeguard from others. However, the first commercially successful modern lock and key system was invented by American mechanical engineer and metalsmith Linus Yale Jr., who received a U.S. patent in 1861.

Yale developed several types of locks, including the Yale Double Treasury Bank Lock, created at the request of the U.S. government. These designs brought him nationwide recognition, but the invention that made him truly famous was the pin-tumbler cylinder lock . Yale died just a few years after receiving his patent. However, every lock and key produced by the Yale & Towne Lock Company since then has proudly carried the Yale name.

Barbed wire (Patent #157,124)

Image: Lexis Chadwick

In an age of video surveillance, barbed wire might seem obsolete. Yet it was crucial to the settlement of the American plains in the late 19th century—and it remains widely used around the world today .

On November 24, 1874, Joseph F. Glidden, a farmer from Illinois, received a U.S. patent for the first commercially successful barbed wire . While several earlier patents had been granted for wire fencing, it was Glidden’s design that proved durable, affordable, and easy to mass-produce—making it the dominant form of fencing on the frontier**.**

Air conditioner (Patent #808,897)

Image: Prasopchok

On those hot and humid days of summer, we should all be thankful for the work of Willis Haviland Carrier, often called the father of air conditioning. For his efforts, he received the first U.S. patent for a modern air conditioning system on January 2, 1906.

Air conditioning is a complex process that involves refrigeration, dehumidification, air purification, and circulation. Before Carrier’s invention, various individuals had worked on these individual components. But it was Carrier, an American engineer, who successfully integrated them —focusing on the crucial relationship between temperature and humidity.

Orville and Wilbur Wright are credited with achieving the first controlled, manned flight in history. For their pioneering work, they received the first U.S. patent for an airplane, issued on May 22, 1906.

Many had been intrigued by the idea of human flight before them. However, it was the Wright brothers who succeeded in building, flying, and promoting the world's first successful airplane —an invention that revolutionized transportation.

Bakelite (Patent #942,809)

Image: Call Me Fred

The modern plastics industry wouldn’t exist without Belgian-American chemist Leo Hendrik Baekeland , who received the first U.S. patent for a thermosetting plastic in 1909. Before him, others had attempted to produce synthetic resins but were unsuccessful.

Baekeland corrected his predecessors’ mistakes. The result was the first thermosetting resin —one that, once set, would not soften under heat. Bakelite was the first in a long series of resins that shaped the U.S. economy, paving the way for materials such as cellophane, acetate, vinyl, Plexiglas, acrylic, Formica, and polyester.

Do you know where the name Birds Eye Frozen Food comes from? From its inventor! In 1930, American entrepreneur Clarence Birdseye received the first U.S. patent for this type of product.

Food preservation has been a concern since the beginning of time. Techniques such as salting, pickling, smoking, curing, canning, and later inventions like the icebox and home refrigerator have all contributed to preserving food.

However, one of the most successful methods was developed and commercialized by Birdseye. His process involved quick-freezing meat, seafood, vegetables, and fruit in convenient packages without altering their original taste. Birdseye’s name became a household word, and his innovation created a multibillion-dollar industry.

Instant photography (Patent #2,543,181)

When we think of instant photography, Polaroid is often the first name that comes to mind. But how much do we know about the man behind the company? American scientist, inventor, and co-founder of the Polaroid Corporation, Edwin Herbert Land , was granted the first U.S. patent for a one-step photographic process in 1951.

While on vacation with his family, Land conceived the idea for a camera and film that could produce an immediate photograph. In 1948, the first Polaroid Land Camera went on sale, though without much public approval. Polaroid continued to improve the Land Camera and, in 1965, introduced the affordable Swinger model , which became an immediate success. Throughout his life, Land was granted more than 533 patents, was inducted into the National Inventors Hall of Fame, and received the Presidential Medal of Freedom.

Back in 1986, Bay to Breakers set the Guinness World Record for the largest footrace, with 110,000 registered participants. If you want to understand what type of sports event would summon so many athletes, you need to picture a unique blend of a race and an all-out costume parade.

This 7.5-mile course stretches from the San Francisco Bay (at Howard Street) to the Pacific Ocean. Held every third Sunday of May, the event is a local party where people wear elaborate costumes —think cartoon characters, colorful animals, and even synchronized group outfits. Bay to Breakers began in 1912 as a way to boost morale in San Francisco after the devastation of the 1906 earthquake.

Running of the Bulls

You’d be wrong to think that the San Fermin Festival is only held in Pamplona, Spain. In 2007, New Orleans created its own version of the "Running of the Bulls." Here in the U.S., participants dress in all-white clothing with red accessories, as per tradition. But they don’t run from bulls: they run from roller derby skaters wearing horned helmets , wielding plastic bats, and chasing them around the streets.

Held in the summer to coincide with Pamplona's festival dates, this event is accompanied by food, drinks, live music, and a lively atmosphere that blends Spanish and New Orleans styles.

Did you know that you can sail inside a pumpkin ? This is standard procedure at Goffstown Pumpkin Regatta, held every autumn in New Hampshire. In the year 2000, local growers envisioned an event that would turn oversized pumpkins—some weighing as much as 1,000 pounds—into something fun and unusual.

Their challenge? Hollowing out massive pumpkins to turn them into boats, to then paddle them in a regatta down the Piscataquog River. Over the years, more and more contestants signed up to participate with flamboyant pumpkin designs and matching costumes. Of course, the event also features a pumpkin weigh-off , craft and food vendors, as well as live music and games.

Twins Days

Twinsburg, Ohio, decided many decades ago that it was the perfect location to hold a yearly celebration of twin siblings. After all, the town was named after identical twin brothers who owned most of the land in the 1800s. Over the years, the festival has grown to become the world’s largest annual gathering of twins, triplets, and other multiples.

Traditionally, all participating twins show up dressed either identically or mismatchedly. Some of them even showcase their talents, ranging from music to comedy. Among food stalls, carnival rides, and live music, there is also a "Research" spot. There, scientists and researchers attend to study willing twins for insights into genetics, biometric data, and their health conditions.

Houston’s Art Car Parade began in the 1980s as a way to promote unconventional creativity and art . Back then, only 40 vehicles participated, but today the festival has become one of the most colorful art car parades in the world.

Participants transform their cars, bikes, and other vehicles into mobile artworks for this yearly parade held every April. Cars with the most outrageous designs—styled to look like dragons, unicorns, fruits, or even structured to appear to be stacked on top of one another—have been featured in past celebrations. Nowadays, the parade attracts over 250 art cars from across the U.S., as well as an audience of 250,000 lined up to watch.

A beach invaded by corgis sounds like a heavenly sight for dog lovers . Every year at Huntington Beach, California, this event gathers corgi enthusiasts and their furry friends to celebrate their love for the breed.

Sometimes the dogs wear costumes, and contests are run with categories like "Best Themed Outfit" and "Cutest Corgi." Short races are also organized, though owners know their corgi's legs aren't built for speed, so the event is held in good humor to watch the corgis happily walk around. Mr. Pickles the Corgi, the mascot of the event, has become an internet sensation. Of course, the beach day features merchandise stands with corgi-themed products for dogs and their humans to take home.

Fremont Solstice Parade

Organized on the Saturday closest to the summer solstice in Seattle’s Fremont neighborhood, this celebration has become a symbol of creativity, self-expression, and community . It was conceived in the late ‘80s to counter corporate-sponsored parades, which locals found cold and generalistic. They decided to combat it by organizing a parade that would showcase warmth and individuality.

The parade prohibits motorized vehicles, written words, and commercial logos. Only handmade arts and crafts are allowed. Puppets, dance troupes, musicians, and giant kinetic sculptures are often seen parading the streets of Freemont under the sun. The event usually wraps up at sunset with picnics and music at Gas Works Park.

Underwater Music Festival

You read that correctly. There’s an underwater music festival held every summer at Looe Key Reef , off the coast of the Florida Keys. The event was designed to combine two things the region is known for: the preservation of marine life and laid-back music.

Don’t worry, the music is not played directly underwater. Musicians pre-record the performances and these are transmitted through waterproof speakers placed along the reef. The playlist also often includes water-themed hits like "Yellow Submarine" by The Beatles and "Fins" by Jimmy Buffett. Many participants show up to dive in wearing fanciful costumes, like mermaids or sea creatures.

Some of the most famous festivals across the country are Renaissance fairs that draw visitors into an immersive celebration of medieval and fantasy culture . The largest of these is the Texas Renaissance Fair, which takes place on a former strip-mining site near Houston.

Hundreds of thousands of fans flock to this festival. It features a 55-acre village with cobblestone streets, themed buildings, and costumed performers. In it, fans can wander through medieval taverns , blacksmith shops, and artisan booths. Different shows add to the atmosphere, including jousting tournaments and falconry demonstrations. The event is held over several weekends, each with a different theme, such as Oktoberfest, Pirate Adventure, or Celtic Christmas.

We conclude with the only festival in the country where you could ask for garlic ice cream . Until 2019, every July in Gilroy, California, garlic growers and lovers would gather for the Gilroy Garlic Festival, which had become a world-renowned event. Sadly, after 2020, the event was discontinued.

Of course, you could approach the food stands and ask for your typical garlic fries or garlic bread. But there was much more to do. You could attend cooking demonstrations, and garlic-themed contests (like the garlic-braiding competition), and enjoy live music across several stages. There was also a Miss Gilroy Garlic Queen pageant, where contestants were judged not only on traditional pageant criteria but also on their knowledge of garlic.

Custer, Idaho, was born from the 1870s gold rush, and later grew after a fire destroyed the nearby town of Bonanza. As mining dried up, the once-busy one-street town was abandoned, leaving behind rusted equipment and relics like a bullet-riddled poker table.

Thanks to its designation as a historic site in 1981, parts of Custer have been restored. Summer visitors can tour cabins, a schoolhouse, and the old saloon.

Jazzland was a theme park in New Orleans that opened in 2000. After major investments, it reopened in 2003 as Six Flags New Orleans. Following Hurricane Katrina in 2005, the park was submerged, with murky floodwaters destroying roughly 80% of the property. Rides were wrecked, stands overturned, and only the Batman coaster survived on higher ground .

Deemed too costly to repair, the park was abandoned and now draws curious urban explorers.
