NYC

Buying a hot dog in New York City is as easy as breathing. Just get out on the street, and you will find a hot dog cart. The key components are simple, but tried and true. A beef frankfurter (usually boiled) on a hot dog bun, onions, and sauerkraut. For the condiments, mustard does the trick. Decades of New Yorkers repeating the recipe tell us that it works.

Chicago

Chicagoans do not share the New Yorkers' simple approach to hot dogs. They are all about the accoutrements. On a poppy-seed bun, a beef frankfurter is loaded with seven specific toppings: yellow mustard, white onions, sweet pickle relish, dill pickle, tomatoes, pickled peppers, and celery salt. Not for the faint of heart.

Cincinnati Coney

One of the most famous coneys —or hot dogs topped with meat sauce—a Cincinnati-style hot dog takes toppings in a totally different direction. The usual frankfurter and bun (toasted, obviously) are now the vehicle for a spread of mustard, a generous scoop of Cincinnati chili —much more spiced than your regular chili con carne, with cinnamon, allspice, cumin, and cloves—, and a helping of finely-diced yellow onions. If you are in the mood for a cheese coney, you can add shredded cheddar cheese to your heart's desire.

Sonoran

Popular in Arizona but with roots in the Mexican state of Sonora, this hot dog proudly displays its ancestry. The typical bun is replaced by a Mexican-style bolillo bun, with a crunchy crust but a soft interior. The sausage is wrapped in bacon, grilled, and topped with onions, tomatoes, and pinto beans. Popular condiments include mustard, mayonnaise, and jalapeño salsa.

Kansas City

Kansas City deviates from the usual all-beef frankfurter. Instead, a pork sausage(grilled or steamed) is served on a sesame bun and topped with mustard, sauerkraut, and melted Swiss cheese. Another popular variant replaces these toppings with brisket burnt ends and barbecue sauce.

Michigan Coney

Allegedly born among Greek immigrants, the Michigan coney is much more straightforward than its Cincinnati counterpart. While the key elements are the same —an all-beef frankfurter on a steamed bun, topped with chili, mustard, and onions— they are set apart by the meat sauce. Where Cincinnati’s flavors rely on a multitude of spices, Michigan’s chili is beanless, meat-forward, and savory. Different, but not less comforting.

Italian Dog

A New Jersey delicacy, the Italian dog has multiple versions. The og recipe features a deep-fried sausage on an Italian roll, mustard, and a combination of fried peppers, onions, and potatoes. Variations include swapping the traditional hot dog for a different protein or replacing the potatoes with French fries. The addition of ketchup is a point of contention for locals.

Seattle

Seattle-style hot dogs feature an unlikely choice as their star ingredient: cream cheese. Created by a former bagel vendor, the original buns were also bagel-style; however, standard hot dog buns or hogies are now the norm. The buns are toasted and slathered with cream cheese, topped with a grilled sausage and caramelized onions. Jalapeños are also a common addition, and vendors might offer different types of cream cheese.

Cleveland Polish Boy

The star element of a Polish boy is, no doubt, the sausage. In this case, the choice is kielbasa, a smoked meat sausage, either grilled or fried. The typical toppings are barbecue sauce, French fries, and coleslaw. Fun fact: the Polish boy is the center of an ongoing discussion. While it has all the components of a hot dog, many consider it a sandwich.

Texas Tommy

Image: Wright Brand Bacon

Don’t be fooled by the name; this hot dog comes from Philadelphia. Some say that ‘Texan’ was a common way to refer to all hot dogs, and it caught on. What makes a Texas Tommy different? The sausage is opened lengthwise, stuffed with cheese, wrapped with bacon, and then grilled or fried until the bacon is crispy. Considering all that’s going on with the sausage, toppings are left to the consumer’s discretion, although mustard, onions, chili, or extra cheese are popular choices.

Bison

We’ll begin with the national mammal of the United States. Actually, that might be a bit reductive: the bison is not just a national symbol, but it has also been chosen as representative by a plethora of institutions, including the U.S. Department of the Interior, the University of Colorado, and several Great Plains states.

Since the end of the 19th century, indiscriminate hunting made the bison an extremely endangered species: By 1884, only 325 bison remained in the country. Luckily, thanks to the hard work of several conservation agencies, that number has gradually increased over the years, reaching a population of 500,000 bison by 2017.

Prairie dog

Here’s a question for any biologist reading this article: Why, pray tell, are prairie dogs not called "prairie squirrels"? While these mammals possess little to no dog-like features, they are definitely a close relative of squirrels. In fact, they belong to the same family. Food for thought, right?

In any case, prairie dogs are proof that an animal doesn’t have to be big to be important. All five species are considered keystone species to their environments, as their burrowing and mound-building help renew and revitalize the soil of their habitats. Not only that, they are extremely important components of the food chain, since they provide sustenance to many predators.

Alligator

From the warm weather of the American South comes the only reptile on this list. Alligators are truly fascinating creatures: not only do they date back to the age of dinosaurs, but they can also only be found in 2 countries in the entire world—China and, of course, the United States.

While they are certainly deadly predators, don’t let their ferocity fool you: they rarely attack humans, and only when disturbed. Moreover, alligators are key species in maintaining their habitats, not just through population control, but also by encouraging plant diversity through the construction of alligator holes.

Grizzly bear

Anyone who has looked at a picture of a bear has probably thought in disbelief, "How can something that looks this adorable be so dangerous?" While this philosophical conundrum might be the reason that Teddy bears are so popular, the truth is that the grizzly bear is a perfect representative of the duality found in most of these large mammals: a combination of extreme cuteness with dangerous ferocity.

In that sense, we only need to take a look at the etymology of the grizzly bear to find the feral nature of this seemingly adorable creature. When Lewis and Clark first encountered these bears, they recorded their name as "grisley," which many believe comes from a Middle English word for "gruesome."

Gray wolf

Many biologists consider the gray wolf the unsung hero of American wildlife. This majestic hunter is a keystone species in Yellowstone National Park, helping to maintain the elk and deer populations. And while it has notably appeared in many blankets and t-shirts, the gray wolf, sadly, has not been recognized as any state’s official mammal.

Originally, grey wolves’ range covered approximately two-thirds of America, but they can currently be found in the northern part of the country. Most notably, Alaska houses the largest wolf population in the country, with a number between 7,000 and 11,000 wolves roaming the state.

Turkey

There’s an urban legend that states that Benjamin Franklin proposed the turkey to be our national symbol. If the stories are true, there might very well be a universe in which this odd-looking bird represents Americans everywhere. And although we’ll take the bald eagle as a symbol any day of the week, there’s something to be said about the nobility of this game bird.

Unlike their domesticated counterparts, wild turkeys are more adept at flying. Although we may never see a majestic turkey soar through the skies, they are able to fly short distances of up to a quarter mile. What’s perhaps most impressive about these birds is their wide range of vocalizations, which may sound like a simple "gobble, gobble" to us, but convey numerous meanings to other turkeys.

Groundhog

Image: Andy Sanchez

Sure, Beverly Hills might be the home of Hollywood’s royalty, but the borough of Punxsutawney, Pennsylvania, is home to one of America’s most famous stars. Since 1887, a groundhog by the name of Phil (Punxsutawney Phil, to be exact) has been the key figure in the town’s most famous tradition: "Groundhog Day," a celebration in which Phil predicts when will winter end.

While Punxsutawney Phil is perhaps America’s most famous groundhog, the truth is that these quirky rodents are one of America’s most recognizable animals. Interestingly, groundhogs are also known as "woodchucks," which is a rather baffling name, since these creatures are not known for chucking wood of any kind.

Florida panther

The alligator might be Florida’s most famous animal, but this large cat shouldn’t be overlooked. The Florida panther is the only cougar species living in the Eastern United States, with a worrying 200 individuals currently living in the Sunshine State.

This majestic cougar is a source of pride for many Floridians, and numerous conservation campaigns have been launched over the years to help protect its habitat. The Florida panther was named the state’s official animal in 1982, as well as being the namesake of the South Florida ice hockey team.

Roadrunner

Isn’t it strange not to see a coyote included in the title of this entry? We feel bad about separating this iconic pair, but we are sure you’ll agree that the roadrunner is an amazing bird in its own right, even becoming New Mexico’s official state bird in 1949.

Warner Bros. cartoons quickly capitalized on this bird’s most remarkable feature: its running speed. Roadrunners can reach speeds of up to 20 mph, which comes in great help for hunting and running away from predators (like a certain coyote).

Bald eagle

Image: Michael Jerrard

The bald eagle shares the title of "most instantly recognizable American symbol" with the American flag and Mount Rushmore. Its status sometimes makes us forget about the spectacular specimen hiding behind the American icon, so we thought it would be a good idea to close this article with a small tribute to our favorite bird of prey.

Let’s start with the obvious: the name "bald eagle" doesn’t come from any distinct lack of plumage, but rather from the old meaning of the word "bald," which used to stand for "white-headed." This distinction seems necessary because one of the most breathtaking aspects of this bird is the contrast of its feathers, which produces a stunning image when paired with its yellow beak. For a while, the status of the bald eagle was endangered until its population recovered thanks to conservation efforts.

Thomas Edison

When it comes to inventors, we can't fail to mention the incredible Thomas Alva Edison.

Edison was born on February 11, 1847, in Milan, Ohio, and since he was a child, he showed his interest and talent in mechanics and electricity. At the age of 11, he set up his first laboratory in his parents' home, and by the age of 12, he ran his own business: a newspaper he designed, printed, and sold himself.

Creator of the phonograph (the first device capable of recording and reproducing sounds) and a fundamental part in the development and popularization of inventions such as the electric light bulb and the motion picture camera, Edison patented more than 1000 creations during his lifetime. Impressive!

Benjamin Franklin

Born in Boston, Benjamin Franklin was one of our Founding Fathers, the men whose principles, values, and ideas shaped America. But as if that weren't enough, Franklin was also a renowned scientist, inventor, and polymath.

A pioneer in the field of electricity, he's remembered for his famous kite experiment, which demonstrated the electrical nature of lightning and led to the invention of nothing less than the lightning rod. In addition, he's also credited with iconic inventions such as the first efficient wood-burning stove (later known as "the Franklin Stove"), the bifocal glasses, and the glass armonica.

Samuel Morse

Unlike other scientists and inventors on this list, Samuel Morse began his journey in a completely different field: art.

Morse studied at Yale, where he completed his studies in 1810. He then embarked on a trip to Europe to continue his artistic education, but this trip awakened another peculiar interest in him. Frustrated by the communication methods of his time, Morse focused his creativity on finding ways to transmit information over long distances using electrical signals. Thus, the revolutionary telegraph was born, along with its way of communication, the Morse code.

The Wright Brothers

The Wright Brothers were the famous siblings who, in the 20th century, achieved a goal long sought by humanity: flight.

Wilbur and Orville Wright are credited with inventing, building, and flying the world's first successful airplane. As you probably know, on December 17, 1903, they made the first sustained flight in history using the Wright Flyer, their iconic invention.

On that December morning, the brothers flipped a coin, letting fate decide who would be the first to test the aircraft. Although Wilbur won, that first attempt failed. So it was Orville who flew for 12 seconds, traveling 120 feet over Kitty Hawk, North Carolina.

George Washington Carver was born in the 1860s in Diamond, Missouri. In the 1890s, his intelligence and hard work enabled him to enter Iowa State College (now Iowa State University), where he earned a master's degree in agricultural sciences. In 1896, he became the head of the agriculture department at Tuskegee Institute in Alabama, where his career as a professor and a researcher took off.

Thanks to his investigations and tests, George Washington Carver made major contributions to agriculture, including his innovative techniques for crop rotation . In addition, he developed many and varied peanut products, such as oil, flour, soap, and ink, helping to make this crop one of the key products of the country's economy.

The stars and the mysteries of the universe captivated the famous Carl Sagan from an early age. Born in Brooklyn, New York, in 1934, Sagan studied at the University of Chicago, where he earned degrees in physics, astronomy, and astrophysics, eventually working and collaborating with NASA.

His contributions to the field of astronomy earned him a position in projects such as the Mariner, Viking, Voyager, and Galileo missions, thanks to which we have learned a lot about Venus, Mars, and Jupiter. The famous high temperatures of Venus, for example, were confirmed thanks to his work.

Additionally, his book and series Cosmos attracted the public's interest in astronomy, inspiring many others to follow in his footsteps.

Grace Hopper

While computer programming may seem like a modern issue, the pioneers of this field were already working as early as the 1940s.

Grace Hopper graduated in mathematics and physics in 1928 and obtained a master's degree and a Ph.D in mathematics from Yale University in 1934. Famous as a pioneer in the world of programming, Hopper's work began during World War II when she joined the US Naval Reserve. There, she worked on the earliest electromechanical computers and developed extensive and complex manuals to operate them.

Her greatest contribution came from her work with mathematical codes, which she translated and adapted into innovative machine-readable language. That innovation led to the creation of the first high-level programming languages.

Jonas Salk

Jonas Salk is none other than the mind behind a medical milestone: the polio vaccine.

In the 1940s, Salk was beginning his career in medical research. While working at the University of Michigan, his work was crucial in developing the first successful influenza vaccine for the military during WWII. This event marked his later study of the poliovirus.

Polio was devastating during the first decades of the 20th century, but that changed dramatically thanks to Salk's work. The scientist led a team that succeeded in developing the first safe and effective injectable inactivated poliovirus vaccine (IPV) in 1955, and the rest is history.

Barbara McClintock

Although her name may not be as instantly recognizable as some others on this list, her work definitely is. Barbara McClintock has undoubtedly made one of the most significant contributions to medicine and genetics.

In the 1940s and 1950s, she worked with chromosomes, investigating their role in inheritance, which led to discoveries that forever changed our understanding of genes.

Before her, genes were believed to be fixed and immutable. But McClintock came to change that idea with her most famous contribution: the discovery of transposable elements, aka "jumping genes." She demonstrated that jumping genes are present in multiple organisms, including humans, and play an essential role in genetic evolution.

Alexander Graham Bell

Alexander Graham Bell became interested in sound and communication at a young age, something that led to his greatest and most remembered contribution: the telephone.

Although born in 1847 in Edinburgh, Scotland, Alexander Graham Bell settled in the United States in 1871 and became an American citizen years later. It was here that he developed most of his experiments and research.

After years of experimenting with methods to transmit sound through electrical currents, Bell finally spoke into his invention on March 10, 1876, saying to his assistant, "Mr. Watson, come here. I want to see you." That was the first successful telephone call in history.
