The United States has more martial arts schools than any other country – by far. Chances are you or someone you know practiced karate or another martial art growing up. While martial arts gained popularity in the U.S. for many reasons, one name stands out: Jhoon Rhee. Known as the Father of American Taekwondo, Rhee famously taught Bruce Lee how to kick and Muhammed Ali how to punch. His bare-knuckled American dream made an impact on generations of Americans. Guests: Terence Nicholson, a D.C.-bas...

A billion-dollar spacecraft, a daring deep-space mission, and one of humanity’s biggest questions: Where did we come from? NASA’s OSIRIS-REx set out to collect a pristine sample from asteroid Bennu, a cosmic time capsule that may hold clues to the origins of life in our solar system. But the journey was anything but easy. Guests: Erica Jawin , postdoctoral research geologist in the Center for Earth and Planetary Studies at the Smithsonian’s National Air and Space Museum and member of the OSIRIS-...

When we think of serial killers, we tend to think of men—Ted Bundy, Jeffrey Dahmer, Jack the Ripper. But in the 1800s, the deadliest killers often wore corsets. In fact, so many women were arrested for serial poisoning that the era became known as the “Golden Age of Arsenic.” Journey back in time to trace the crimes of Lydia Sherman, a Victorian Era femme fatale who left a trail of bodies in her wake. How did she — and women like her — evade capture for so long? And how did their murders help gi...

There was a time, before Neil Armstrong set foot on the moon, when some researchers believed women were better suited for space than men. In 1961, a group of female pilots—today known as the Mercury 13 —quietly aced NASA’s toughest astronaut tests, even outperforming the Mercury men in some areas. But with the space race heating up, their mission was grounded— but not by science. But what became of America’s first female astronaut candidates? Guests: Margaret Weitekamp , chair of the space histo...

Whether it's live on the Smithsonian National Zoo's panda cam or in front of a crowd, possibly no other animal's sex life is as closely watched as the giant pandas' is. And there's a reason. These cuddly-looking black and white bears just can't figure out how to mate. But, with a little help from science, the once-endangered giant panda is making a comeback. To honor the arrival of the National Zoo's newest giant pandas, we peep into the (not so secret) sex lives of pandas. Guests: Pierre Comizz...

Children say it every day in school, but have you ever wondered why we recite the pledge of allegiance? We journey back to the late 1800s to understand how a massive wave of immigration and sagging magazine subscriptions gave rise to this vow of patriotism. From the Civil War to anti-immigrant nativism and Cold War politics, this one pledge tells many stories. Guests: Debbie Schaefer-Jacobs , curator for the history of education collection at the Smithsonian’s National Museum of American History...

Sojourner Truth was a women's rights advocate known best for her famous speech "Ain't I a Woman." But Truth never actually said these words. In fact, much of the Truth we know… is fiction. Depictions from different artists and journalists have tweaked Truth's legacy to fit their messages, giving her a “kaleidoscopic reputation,” according to Nell Irvin Painter, author of Sojourner Truth: A Life, A Symbol. So how did a speech she never gave make Sojourner Truth one of the most famous women’s suff...

Edmonia Lewis was the first sculptor of African American and Native American (Mississauga) descent to achieve international fame. Her 3,000-pound masterwork, “The Death of Cleopatra,” commemorated another powerful woman who broke with convention… and then the sculpture disappeared. On this return episode of Sidedoor, we find them both. You can see "The Death of Cleopatra" at the Smithsonian American Art Museum.

Imagine this: invisible robbers break into a bank and steal massive sacks of cash, but instead of running away with it they set their haul on the front stoop of the bank in a glass case. Everyone can see the money, but only the robbers can get to it. That’s how IRS Special Agent Chris Janczewski describes the 2016 Bitfinex heist – when mystery hackers made out with over $70 million in Bitcoin. By 2020, their loot had ballooned to over $4 billion. With only digital footprints to follow, federal a...

They carried torches and marched at night. Their goal: defend free speech in America. What started as a small group of young men demonstrating during the 1860 election, snowballed into a mass movement of working-class Americans marching to end slavery. They called themselves the Wide Awakes. And they’re widely seen as the political force that helped elect Abraham Lincoln and spur the Civil War. So why has their story gone untold? And why is now the time to tell it? Guests: Jon Grinspan, Curator ...

Imagine Jaws without the sneaking tuba. Or Psycho without the shrieking violins. Music can help a horror film strike fear in the heart of theatergoers. And you can trace some of these musical scare tactics back to the era of SILENT films — when organists made up film scores on-the-spot. To celebrate the spooky season this year, we're slashing apart a 1917 silent horror film with composer Andrew Earle Simpson to find out how music can be the beating heart of suspense. Grab your popcorn and get sn...

In the Lord of the Rings trilogy, Frodo becomes invisible when he puts the Ring on his finger. Well, at banks in the 1970s, this is basically what happened when a woman put a wedding ring on her finger. Her credit cards would no longer work, and the banks wouldn't count her income as part of the household income. This led to a fight for women's financial independence that gave rise to the landmark Equal Credit Opportunity Act (or ECOA) and the creation of the first women's banks. In honor of the...

During the mid-1800s, one third of all paper money in America was thought to be fake. It was the golden age of counterfeiting, and one exceptionally talented con artist stood out from all the rest. His fakes were nearly perfect…but for a trademark tell. Known to law enforcement only as “Jim the Penman,” this celebrity criminal led many Americans to wonder: can great art truly be criminal?

It’s been called ‘the most noble and absurd undertaking ever attempted by any state.’ During the height of the Great Depression, the U.S government hired out-of-work writers and laid-off reporters and sent them out to record the stories of all kinds of Americans. Called the Federal Writers’ Project, historians have called the program a giant “listening project.” While on our summer break, we’re sharing the first episode of a new podcast series called The People’s Recorder. Host Chris Haley sets ...

For thousands of years, fluffy white dogs could be found across the Pacific Northwest. Their exceptionally soft, crimpy hair was shorn like sheep’s wool, spun into yarn, and woven into blankets and robes by indigenous women who carefully tended them in communities across Coast Salish territory. But a hundred years ago, the woolly dog quietly vanished. Why? Today, the only known pelt of this extinct breed is in the collections of the Smithsonian’s National Museum of Natural History, and it might ...

Black holes could unlock the mysteries of creation and live at the heart of nearly every galaxy. But these invisible balls of extremely dense matter have never been fully understood, especially when they were only a theory. We travel through a cosmic wormhole back to the 1930s to learn how the first astrophysicist to successfully theorize a black hole, Subrahmanyan Chandrasekhar, was ridiculed and rejected by his scientific community. This is the first episode of a two-part journey celebrating t...

If you’ve bought a plane ticket recently, you’ve probably had the option to pay a few extra dollars to offset your carbon emissions. That money might go toward planting some trees… but how many trees?

Money is power. But who's on our money - or isn’t - can be just as powerful. While Lady Liberty has graced American coins and dollars for most of our history, it wasn’t until the 1970s that a real woman appeared on a circulating American coin. But that's about to change. Congress recently authorized the creation of twenty new quarters featuring American women from history. But how do we decide whose likeness gets engraved in our national story? And who makes these decisions? We’ll follow the mon...
