Adam Rippon's Olympic Mesh-capades 27.11.2019 21:44
When professional athletes face the end of their career, many look ahead with uncertainty and wonder: “What’s next?” But when Adam Rippon stood on the Olympic podium in 2018, making history as the first openly gay American to medal at the winter Olympics, he was sure about his next steps. Rippon was a darling of the American Olympic media, entering all of his interviews ready with a joke and a wi...
Apollo 12's Really Close Call 13.11.2019 27:55
On November 14, 1969, just four months after Apollo 11’s “giant leap for mankind,” the Apollo 12 Saturn V rocket took off for the moon. Seconds later, a burst of static plunged the three-man crew into complete darkness while speeding toward space in a nearly dead spacecraft. For the 50th anniversary, we tell the often-overlooked story of Apollo 12, one full of danger, discovery, and the power of f...
Dynamite! 30.10.2019 33:40
In its heyday, dynamite was a transformative tool; it could blast rock quarries, excavate tunnels, and demolish buildings with power and reliability never before seen. But it also proved to be useful in some surprising ways. In this special episode of Sidedoor , we team up with the history podcast Backstory to explore two less-typical applications of the explosive: the artistic blasting at Mount R...
This Episode Smells 16.10.2019 26:33
Smell connects us to memories of the people and the places of our lives. But what if it could connect us to a past we’ve never experienced? That's the goal for one team of artists and scientists who used DNA to try to revive the scent of a flower extinct for more than a century.
The Dinosaur War 02.10.2019 30:01
Behind the fossilized teeth, bones, and claws displayed in the National Museum of Natural History’s new Fossil Hall is the story of two men and a nasty feud. During the paleontology boom of the late 1800s, scientists O.C. Marsh and Edward Cope went from good friends who named species after each other, to the bitterest of enemies who eventually ruined each other's lives and careers. Come for the di...
The Woman in the Frame 18.09.2019 29:01
Did you know that Martha Washington was essential to America’s Revolutionary War effort? Or that Eleanor Roosevelt was the driving force behind the United Nations’ Universal Declaration of Human Rights? According to journalist, writer, and commentator Cokie Roberts, many of America's First Ladies were dynamic, politically engaged trailblazers who are often overlooked. We sit down with the Smithson...
Field Trip! 04.09.2019 28:21
Sidedoor hits the road, sneaking behind the scenes for the ultimate Smithsonian field trip we never took as kids. Lizzie and producer Justin O'Neill journey by bike, train, and even horse (okay, plastic horse) in a romp from museum to museum, encountering a hungry predator, a group of Broadway monsters, the last work of an iconic painter, and lots more. Join us! Links from the episode: Hokusai's...
Memory, Myth & Miniatures 21.08.2019 23:17
David Levinthal is a New York-based artist whose photography depicts “the America that never was but always will be.” He uses toys to recreate iconic moments in American history and pop culture, encouraging his audience to question America’s collective memory. Sidedoor visits Levinthal in his studio, and an exhibition of his work at the Smithsonian American Art Museum titled “American Myth & M...
The Wild Orchid Mystery 07.08.2019 22:55
You probably know orchids as the big, colorful flowers found in grocery stores and given as housewarming gifts. But those tropical beauties represent only a fraction of the estimated 25,000 orchid species worldwide. While their showy relatives fly off the shelves, North America’s more understated native orchids are disappearing in the wild. Scientists at the Smithsonian Environmental Research Cent...
Things You'd Never Tell Your Parents 24.07.2019 20:03
Regie Cabico has been called the "Lady Gaga of Spoken Word poetry"—he's outspoken, provocative and iconoclastic. The son of Filipino immigrants living in rural Maryland, Regie says he’ll never be “entirely American or entirely Filipino,” and on stage he uses his poetry to explore identity, social issues, and (of course) love. Regie joins Sidedoor *in studio* for an exclusive live performance, and...
Space Jocks & Moon Rocks 10.07.2019 26:23
When NASA’s Apollo 11 mission sent the first astronauts to the moon 50 years ago, there were many things we didn’t know. Like whether the moon’s surface would turn out to be a field of quicksand, if space germs would infect the astronauts, or what exactly the moon was made of. To commemorate the 50th anniversary of the Apollo 11 moon landing, we join forces with the National Air and Space Museum’s...
The Worst Video Game Ever? 26.06.2019 25:48
Deep within the National Museum of American History’s vaults is a battered Atari case containing what’s known as “the worst video game of all time.” The game is E.T. the Extra-Terrestrial, and it was so bad that not even the might of Steven Spielberg could save it. It was so loathsome that all remaining copies were buried deep in the desert. And it was so horrible that it’s blamed for the collapse...

Aloha, Y’all 24.04.2019 29:22
Close your eyes and think of Hawaii. That sound you undoubtedly hear? Well, that’s the ocean. But that other sound floating on the breeze—that’s the steel guitar, an indigenous Hawaiian invention that has influenced country, blues, and rock music since the turn of the 20th century. This time on Sidedoor, we follow a familiar sound with an unexpected origin and learn how the steel guitar helped H...
Good as Gold 10.04.2019 21:08
Glittering treasures, gleaming coins, and eye-catching jewelry…gold can be all of these things, but in some parts of the world it's also an enduring link to the past. Gus Casely-Hayford, director of the Smithsonian’s National Museum of African Art, takes us on a journey through West Africa to learn how gold was the foundation for massive empires—and his own family—and how it continues shining brig...
Abraham Lincoln: Prankster-in-Chief 01.04.2019 32:34
We all know Abraham Lincoln, right? Well, we know one side of him—the grave-faced leader of a troubled country—but behind the face on the penny lies an unlikely jokester. This week, Sidedoor reveals the rascally side of our 16th president, and does it with a brand-new sound.
The Feather Detective 27.03.2019 27:10
In 1960, investigators found dark bits of feather stuck inside a crashed airplane's engines. They needed someone to figure out what bird they belonged to—and how that bird took down a 110,000-pound plane. Enter Roxie Laybourne, a Smithsonian bird expert who not only answered that question, but also invented the science of using feathers to solve bird-related mysteries. This time on Sidedoor, we re...
Singing the Gender-Bending Blues 13.03.2019 26:58
Gladys Bentley loved women, wore men's clothing, and sang bawdy songs that would make sailors blush...and did it openly in the 1920s and 1930s. This was long before the gay rights or the civil rights movements, yet Bentley became a darling of the Harlem Renaissance alongside icons like Langston Hughes and Josephine Baker. While her provocative performances kept her from becoming as well-known as h...
The Silence of the Frogs 27.02.2019 26:06
In the mid-1990s, investigators identified a mysterious and seemingly unstoppable killer. Its name? Chytrid. Its prey? Frogs. Since then, the disease has ravaged frog populations worldwide, and despite decades of research there’s still no cure. So, like modern-day Noahs, a group of Smithsonian researchers have resorted to a time-honored plan: building an ark…for amphibians. This time on Sidedoor...
Cheech Marin Gets Artsy 13.02.2019 26:24
In the 1970s and ’80s, Cheech Marin was famous for being half of the stoner comedy duo "Cheech and Chong." Today, he’s a passionate advocate for Chicano art and is raising awareness around a uniquely Mexican American aesthetic: rasquachismo. In this episode of Sidedoor, Cheech Marin is our guide to the wildly creative and ingenious world of rasquachismo—the Chicano art of working with what you've...
50 Shades of Gray Whales 30.01.2019 25:27
Happy New Year! We’re busy working on a new batch of Sidedoor episodes and while you wait, we wanted to re-share a story we like from the fall, just in case you missed it the first time around. From 6,000-year-old cave paintings to silver screen stars in movies like Free Willy, whales have long captured the human imagination. And it makes sense—they're among the largest and most intelligent creatu...
Amelia Earhart's Revolutionary Flight Club 26.12.2018 26:38
You know Amelia Earhart, but did you know she was just one of a daring group of women aviators who defied both expectations and gravity in the 1920s? They called themselves the Ninety-Nines, and they’re still flying today as an organization dedicated to the advancement of women pilots. This time on Sidedoor, we time-travel to the Roaring ‘20s to experience America's first official all-female air r...
Inventor, Photographer...Murderer 12.12.2018 27:31
Meet Eadweard Muybridge, a pioneering and eccentric photographer from the 1800s whose work changed how people understood movement, and paved the way for the invention of motion pictures. But this inventor, artist, and showman also made a name for himself for something much less savory: murder. This time on Sidedoor, come for the ingenuity and stay for the scandal as we find out how a near-death ex...
This Color Is Who I Am 28.11.2018 27:30
Artist Frank Holliday's social circle in the 1980s was a who's who of New York City cool: Andy Warhol, Cyndi Lauper, RuPaul, Keith Haring, and even Madonna. But Frank's odyssey through the art world also placed him at the center of an epidemic that would shake the entire country. In honor of World AIDS Day, Sidedoor takes a look at America's early HIV/AIDS Crisis through the eyes of an artist whos...
