Sidedoor
More than 154 million treasures fill the Smithsonian’s vaults. But where the public’s view ends, Sidedoor begins. With the help of biologists, artists, historians, archaeologists, zookeepers and astrophysicists, host Lizzie Peabody sneaks listeners through the Smithsonian’s side door, telling stories that can’t be heard anywhere else.

How Can You Forget Me
Everyone thought ghosts lived in the basement of Stockton, California's old Daguhoy Lodge. So, nobody went down there. But when one man refused to be spooked, he made a discovery that would bring the ghosts back to life. In this episode, we explore how an accidental discovery resurrected the stories of a nearly forgotten generation of Filipino immigrants who came to work in the fields. Wh
High Art, Low Ride
How did a car with chopped suspension and hydraulics become a symbol of pride and self-expression for an entire community? We'll cruise back in time to see how lowriders emerged from the post-WWII car craze and became a powerful symbol of Mexican American pride. It's a long road with a few speed bumps, but lowriders are now more popular than ever (especially in Japan!)So, lean your seat b
The People in the Pictures
At the Smithsonian’s National Museum of the American Indian, archivists are working with Native communities to correct the historical record … one photo at a time.In this episode, we go inside the archives, where century-old photographs once labeled “Indian man” or “woman in costume” are being reexamined and renamed so they can be reconnected to living descendants. It’s a painstaking effo
May the 4th Be With You
A long time ago, in movie theaters not far away, Star Wars: A New Hope revolutionized American entertainment. In honor of May the 4th, we explore how a scrappy space fantasy reinvented a tale as old as time — and gave Americans hope in a time of difficulty. We'll also trace the journey of two bickering droids from a galaxy far, far away to the Smithsonian's National Museum of American His
Broad Stripes, Bright Stars, and White Lies
As we approach the nation's 250th birthday, we are looking back at some of the most important moments in American history. One of those moments is when Betsy Ross sewed the first American flag. But, as we discovered, there’s actually no proof that Ross sewed the first flag. In fact, we don't even know what the first American flag even looked like! In this episode of Sidedoor, we unravel t
Tapir Caper
When a Smithsonian archaeology intern opened a dusty box of bones in a Panamanian warehouse, she didn't expect to find a mystery, let alone a potential crime scene. But Nina Hirai’s discovery of a tapir skull riddled with what appeared to be bullet holes sparked an investigation that would lead her several miles up the Panama Canal and nearly forty years into the past. Join us as we unspo
Made in America
What does it look like for something to be made in America? Through the photography of Christopher Payne, we journey across the past, present and future of American manufacturing to answer this question. From centuries-old textile mills to modern assembly lines, Payne’s photographs offer a rare, behind-the-scenes view of how everyday objects—from pencils to airplanes to marshmallow Peeps—
Dark Matter, Bright Mind: How Vera Rubin Saw the Unseen
Something dark and invisible makes up as much as 90 to 95 percent of the universe—and it took a little girl staring out a bedroom window at the night sky to bring it to light. As a child, Vera Rubin built her own telescope. As an adult, she uncovered a problem no telescope could solve: stars at the edges of galaxies were moving just as fast as those near the center. The math contradicted
Chinatown Murder Case
A string of unsolved murders in San Francisco's Chinatown in the 1970s led police to the door of a young Korean immigrant named Chol Soo Lee — who was quickly arrested and sentenced to life in prison. But when investigative journalist K.W. Lee started digging into the case, he discovered a world of twisted law and order that went far deeper than one man. The articles K.W. wrote about what
The Wright Sister
Orville and Wilbur Wright have been immortalized as the men opened the skies to human flight. But could they have achieved such great heights without the wind beneath their wings — their sister? Katharine Wright was her brothers' biggest champion, official spokesperson, closest confidante and the only one of the Wright siblings with a college degree. For years, Katharine, Wilbur and Orvil
The King of Zydeco
Clifton Chenier grew up in rural Louisiana, watching how his father’s accordion could magically turn front porches into dance parties. When he was old enough to play himself, Chenier began blending the Creole zydeco of his childhood with R&B and blues sounds of the 1940s and ’50s. His style packed dance halls across Louisiana and eventually carried zydeco to stages around the world. T
Will the Real Uncle Sam Please Stand Up?
He’s a symbol of patriotism, protest, and power. But behind the red, white, and blue is a real man—and a disputed American origin story.

A Mold with a Grudge
It started with a messy lab and a mysterious mold. But turning “mold juice” into the world’s first antibiotic would take a sick policeman, a market cantaloupe, and an extraordinary wartime collaboration between scientists, governments, and industry. This is the story of how penicillin changed the world.Guests:Kevin Brown, Trust Archivist to Imperial College Healthcare NHS Trust and curato

Monkey Mystery: The Case of the Capuchin Kidnappers
Why are capuchin monkeys kidnapping howler monkey babies in Panama? We investigate this bizarre case of primate abduction with researchers working with the Smithsonian to get to the bottom of this bizarre behavior. We'll talk about their discoveries, the social dynamics between capuchins and howler monkeys, and the bizarre island conditions that might be driving this behavior. Is it bored
The Music of Jeopardy! From a Lullaby to $100,000,000
It’s the most recognizable TV theme in America. But Jeopardy’s “Think Music” wasn’t originally written for a game show… It was written for a toddler. In this episode, we trace the unlikely journey of the Jeopardy theme, from Merv Griffin’s living room to over 10,000 episodes across six decades. Along the way, we explore the show’s sonic evolution, including honking buzzers, 80s synths, an

Back to School: Origins of the Pledge
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-Jaco
Bear Trouble
When a black bear in Minnesota woke up from hibernation in the middle of winter and attacked three people and a dog, researchers were left with one question: Why?***This episode of the Points North podcast is part of our summer playlist to keep you entertained while Sidedoor is on summer break. We’ll be back in the fall with brand new episodes of Sidedoor. Credits: Producer: Ellie Katz E
Shellshocked II: Turtle Thieves
Turtles are built like tiny tanks—ancient, armored, and famously tough. But in the modern world, that toughness may be their greatest vulnerability. In part two of our turtle two-parter, we dive into the shadowy world of turtle trafficking, where backyard collectors, international smugglers, and unsuspecting pet owners all play a role. From sting operations to turtle triage, we meet the u
Shellshocked I: Turtles vs. The World
Turtles have been around for 200 million years—outliving dinosaurs, surviving ice ages, and basically minding their own business the whole time. Tough on the outside, chill on the inside, they seem built to last. So why are they suddenly disappearing? In part one of this two-part series, we hit the trail in search of one surprisingly elusive reptile: the eastern box turtle. These ancient
Bloodsuckers!
Leeches don’t get a lot of love. They’re slimy, wriggly, and, well, they suck—blood that is. But there’s a lot to learn about the lowly leech. Led by a troupe of Smithsonian experts, we’ll discover how these toothy hangers-on wormed their way into medical practices, performance art, and EVERY human cavity. Yes, even that one. It's a journey of discovery from the swamp to the stage and dee
The Giving Game
The Gilded Age was a time of unparalleled wealth and prosperity in America — but it was also a time of staggering inequality, corruption, and unchecked power. Among its richest figures was Andrew Carnegie, the steel magnate who built his fortune on the backs of low-paid workers, only to give it away — earning him the nickname the Godfather of American Philanthropy. He didn’t just fund lib
Space Jams
If you were curating a mixtape that might be heard by aliens billions of years from now - but definitely would be seen by your fellow Earthlings - what would you put on it? In 1977, two Voyager spacecraft launched from Cape Canaveral on a journey that would take them beyond our solar system. Affixed to the side of these two planetary explorers was the Voyager Golden Record — the ultimate

The Curious Case of the Dizzy Kudu. Rhinos with an unexplained skin disease. A lion that could barely chew. Who do you call when there's a mystery at the zoo? The Smithsonian National Zoo and Conservation Biology Institute's anatomical pathologists. These highly-skilled vets search for clues to investigate animal disease and death — sometimes encountering bizarre phenomena. So, grab your
Writing on the Wall
From the time we’re old enough to hold a crayon, it feels instinctive to draw on the wall. But for MISS CHELOVE – also known as Cita Sadeli – this instinct became a calling. Through bold color and layered symbolism, she transforms everyday public spaces into deeply personal statements, inspiring some passers-by to wonder: what is the role of the public artist? And how can public art both

The Art of the Fist
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 b
Asteroid Tag
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 fo
Poison and Poisonability
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
Right Stuff, Wrong Sex
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
To Sweat Like Beyoncé
Beyoncé is one of the most well-known and appreciated Black women in music today, but to understand her work, we need to look at who came before her and what those women contributed to the story of Black women on stage.

The Sex Lives of Giant Pandas
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 Na

Midnight Magic
"I’m not superstitious, but I’m a little stitious.” As the New Year approaches, this iconic line from The Office feels more relatable than ever. From gulping grapes in Spain to donning yellow underwear in South America and practicing Scotland’s ancient “first-footing” tradition, people around the world embrace odd – and oddly meaningful - rituals to ensure good luck in the year ahead.

The Whole Truth
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:
Finding Cleopatra
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 Smithsoni
Bitcoin Bank Heist
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 Bit
The Wide Awakes
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 Civi
The Devil’s Composer
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
Bankers in the Boudoir
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
Jim the Penman
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?

In the twentieth century, the jetpack became synonymous with the idea of a ‘futuristic society.’ Appearing in cartoons and magazines, it felt like a matter of time before people could ride a jetpack to work.

A Giant Listening Project
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,
The Lost Woolly Dog
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 th

Cosmic Journey I: "Stellar Buffoonery"
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 ridi
Cicadapalooza
The cicadas are back for some fun in the sun, and this time, they’re louder than ever! For the first time since 1803, Broods XIII and XIX will be emerging at the same time, covering the American South and Midwest with trillions of cicadas. As Smithsonian entomologist Floyd Shockley readies his nets for the biggest bug invasion in centuries, we look back at the emergence of Brood X in 2021

Dude, Where’s my Carbon?
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? Researchers at the Smithsonian Tropical Research Institute are trying to answer this very question by hand-measuring trees, weighing wood, and climbing to the top of the canopy. We tag along
Monkeyin' Around on the Devil's Island
It started as a rumor in the cafeteria of the Smithsonian Tropical Research Institute in Panama: monkeys on an island in the Pacific were doing something no one had ever seen them do before. But when researchers went searching for these elusive capuchin monkeys, they discovered more questions than answers.

Face Value
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 d

A Wild Ride on the Pony Express
In 1860 the fastest way to get a message to a family member, partner, or colleague wasn’t by text but by hoof…specifically, a pony’s. In just ten short days the Pony Express delivered mail between St. Louis and Sacramento. To find out what it was like to travel this legendary trail, there’s only one way: get on a horse and follow all 2,000 miles of it. That’s what writer Will Grant did, r
The Hungerford Deed
When a 200-year-old legal document anonymously arrived at his office, Smithsonian Libraries and Archives conservator William Bennett assumed it would be full of boring legal jargon. Instead, he found a juicy tale of family betrayal that would forever change what we thought we knew about the founding of the Smithsonian. In honor of the Smithsonian’s 177th birthday, we’re sharing one of our
Tyrannosaurus FX
When you imagine the sound of a dinosaur, you probably think of a scene from the Jurassic Park movies. How do sound designers make these extinct creatures sound so believably alive? And what does modern paleontology tell us about what dinosaurs REALLY sounded like?

The Toxic Book of Faces
Before the invention of photography, only the rich could afford to have portraits of themselves. But in the early 1800s, a device called the physiognotrace democratized portraiture, making it possible or everyday people to have their images captured in silhouettes. A man named William Bache traveled the United States creating hundreds of silhouette portraits with the aid of the physiognot
Building a Movement
America has a long history of clustering heavy industry and toxic facilities in communities where people of color live. But in the 1980s, a series of events sparked a movement to fight back against these environmental injustices.
