According to many historians, at just 16 years old, Sybil Ludington rode about 40 miles through the night in 1777 to alert American militia of a British attack on Danbury, Connecticut.

This would make her ride roughly twice as long as Paul Revere’s . While some scholars question the veracity of her story, a statue stands in her honor in Putnam County, New York.

A college professor turned Union colonel, Chamberlain famously held Little Round Top during the Battle of Gettysburg, a pivotal moment in the Civil War.

He was awarded the Medal of Honor and later became governor of Maine, but his unexpected battlefield brilliance is often overlooked in Civil War discussions.

Known as the "Father of the FDA," Harvey Wiley was a chief chemist in the late 1800s whose "Poison Squad" tested various food additives, leading to the 1906 Pure Food and Drug Act.

This law laid the foundation for the FDA and led to the removal of many dangerous substances from consumer products. Notably, it prompted Coca-Cola to eliminate cocaine from its formula in the early 20th century.

The Donner Party was a group of pioneers who migrated to California in a wagon train from the Midwest. Delayed by a multitude of mishaps, they spent the winter of 1846-1847 snowbound in the Sierra Nevada .

While the journey west usually took between four and six months, the Donner Party chose to follow a new route called the Hastings Cutoff, which delayed them greatly.

Marx Bros

We’ll start strong with the family of actors considered by many to be the most groundbreaking comedians of their generation: the five Marx Brothers. They truly took the world by storm, leaving an unforgettable mark that forever changed Hollywood.

Throughout a career that lasted over 40 years, the Marx Brothers starred in 14 films, five of which were included in the American Film Institute's list of the greatest 100 comedies of all time. While it is indeed a gargantuan task to select the best moments from this remarkable career, we feel inclined to select 1933’s Duck Soup and 1935's A Night at the Opera as our top picks.

Abbot and Costello

In the very likely event that you’ve ever played a game of baseball, we can almost guarantee that someone jokingly asked you, "Who’s on first?" in a marked Jersey accent. After all, any American born after the 1950s knows this legendary Abbott & Costello routine, which is considered by many to be one of the finest pieces of comedy ever conceived.

This iconic duo met in New York City in 1935. After Bud Abbott’s comedy partner fell ill before a performance at the Eltinge Burlesque Theater, Lou Costello substituted for him, marking their first unforgettable performance. Many believe the duo’s groundbreaking chemistry was already present in that very first show. Over the course of their nearly 20-year career, Abbott & Costello produced several hilarious routines, including "Niagara Falls," "The Piano Bit," and, of course, "Who’s on First?"

Jerry Seinfeld

Years before he starred in his groundbreaking Show About Nothing , Jerry Seinfeld was a scrawny and hilarious comedian making appearances on talk shows like The Tonight Show Starring Johnny Carson and Late Night with David Letterman . While this young comedian’s talent was evident, little did anyone know that Jerry Seinfeld would soon become the world’s most famous comedian.

The TV show Seinfeld ran for 9 seasons between 1988 and 1998, winning a myriad of accolades and awards in the process. Part of the charm was that Jerry’s off-screen persona seemed like a carbon copy of his character: he was witty, sarcastic, and hysterically funny. After Seinfeld concluded, Jerry went on to produce several successful comedy specials, as well as the Emmy-nominated show Comedians in Cars Getting Coffee .

Johnny Carson

While Johnny Carson was not the first host of The Tonight Show , he is definitively considered a pioneer in late-night TV history. This groundbreaking comedian hosted the iconic talk show for 30 years, earning the well-deserved title of "King of Late-Night Television" in the process.

It’s difficult to describe how immense Carson’s influence was, not only on the history of talk shows but also in American culture in general. It only takes someone mimicking a swing of a golf club for anyone to realize they are paying tribute to this legendary comedian. Johnny received numerous awards during his lifetime, including six Primetime Emmys and the Presidential Medal of Freedom.

Conan O’Brien

Conan O’Brien is truly a blue-collar comedian. Now, by no means are we trying to convey that other comedians didn’t work hard to get where they are; we are simply pointing out that Conan’s comedy resume dates back to his early twenties when he started writing for groundbreaking shows like Saturday Night Live and The Simpsons .

In 1993, Conan debuted as a late-night host with Late Night with Conan O'Brien . What followed was a 28-year career filled with hilarity and creativity, which only ended after Conan announced he would be retiring and taking a well-deserved break from performing. However, he still continues to host a hilarious series of podcasts called Conan O'Brien Needs a Friend .

Jackie Gleason

If you happen to visit New York City (or if you are a New Yorker yourself), take a stroll to Port Authority Bus Terminal, and you’ll come across an eight-foot-tall bronze statue of a cheerful and lively bus driver. If you take a closer look, you’ll notice that this is not a homage to any real-life bus driver. In fact, the man depicted in the statue is none other than the legendary comedian Jackie Gleason , portraying Ralph Kramden, his iconic character from The Honeymooners .

First broadcast in 1955, The Honeymooners was a groundbreaking sitcom that depicted the life of bus driver Ralph Kramden and his wife Alice. This show served as the inspiration for countless other sitcoms, including America’s favorite prehistoric family, The Flintstones .

Robin Williams

Robin Williams’ legacy expands throughout several generations: People in the ‘70s adored him in Mork and Mindy , he inspired many ‘80s moviegoers with his films Good Morning Vietnam and Dead Poets’ Society , and he filled the childhoods of millions of ‘90s kids as the wisecracking genie from Aladdin .

What’s perhaps most astounding about Williams’ acting is the remarkable range he displayed. The fact that his performances in drama could move us to tears doesn’t diminish the effectiveness of his comedy chops. Not only that, but hundreds report that off-screen, Williams was an incredibly kindhearted and warm person, always ready to go the extra mile to make someone smile.

Chris Rock

Don’t let the title of his Emmy-nominated TV show fool you: Not everybody hates Chris Rock . In fact, we are willing to go even further and state that, despite being known for his crude and sarcastic style, he is still one of America’s most beloved comedians.

Chris Rock's first jump to prominence came when he joined the main cast of Saturday Night Live in 1990. After that, he went on to perform in several stand-up specials and provided hilarious comic relief in films such as Lethal Weapon 4 , The Longest Yard, and Death at a Funeral .

Steve Martin

In 1967, thousands of American families tuned in to watch another episode of the extremely popular game show The Dating Game . While that particular installment came and went without a second thought, it marked legendary comedian Steve Martin ’s first appearance on national television. Little did anyone know that it wouldn’t be by any means his last.

It was only a few years after that appearance on The Dating Game that Martin took the world by storm. By the mid-1970s, he was already showcasing his hilarious routines on shows like The Tonight Show Starring Johnny Carson , The Muppets, and Saturday Night Live . Today, at 79 years old, Martin continues to be as hysterical as ever, starring in the acclaimed show Only Murders in the Building .

Charlie Chaplin

While it is true that Charlie Chaplin was English, it would feel wrong not to include such a Hollywood legend in this list. In that regard, we have reserved the last spot for someone who many consider to be the best comedian of all time. Chaplin’s career goes as far back as the early days of cinema, first appearing as his iconic "Tramp" character in the 1914 film Kid Auto Races at Venice .

What’s perhaps most remarkable about Chaplin’s legacy is not only his hilarious and groundbreaking skits but also his unique ability to both inspire and entertain his audience. We’ll close this article by remembering what is probably his most famous line of dialogue (and that’s saying something for a mostly silent actor): the final speech in his 1940 film The Great Dictator .
