Bonus Episode: Tempest in a Teacup 02.12.2020 34:20
This week, we have an episode from the NHPR podcast “Outside/In” about passenger pigeons. The passenger pigeon is one of the world’s most symbolic extinction stories. It’s a cautionary tale of how in just a few short generations, one of the wonders of the world could be completely eradicated. But when that narrative was questioned in a popular book, 1491 by Charles Mann, what does the response tel...
Bonus Episode: That Time the FBI Called 18.11.2020 24:25
This week, we’re sharing an episode of ‘Detours,’ a new podcast from our friends at GBH and PRX. The podcast shares surprising stories that unfold behind the scenes at the PBS classic TV show “Antiques Roadshow.” In this episode: a rare daguerreotype, Edgar Alan Poe, and…the FBI. You can find ‘Detours’ wherever you listen to podcasts.
The Gorilla Epidemic 14.10.2020 31:10
When a highly-contagious mystery illness spread through the world’s mountain gorilla population, biologists feared the entire species could be lost. Gorillas don’t wear masks or social distance, so there wasn’t much time for the scientists to identify the illness and find a cure for humanity’s hirsute cousins. What they found in 1988 reminds us in 2020 that humans and wildlife share more than a pl...
Dress Coded 30.09.2020 28:52
Dress codes have been around a long time—from the old days of long skirts and bloomers to today’s regulation-length shorts. But while the specifics of what girls can wear to school have changed, the purpose of the codes has not.
Appalachia Goes Beijing 16.09.2020 24:16
When Abigail Washburn and Wu Fei first jammed together, “it was magic.” Fei was shocked to meet an American banjo player so curious about China’s culture; and Abigail Washburn met a classically trained composer whose talents on the guzheng, a 2500 year old 21-string Chinese harp, perfectly complimented her banjo pickin’. Today, they collaborate to make a new brand of folk music: one that combines...
The People's Insect 02.09.2020 27:51
To look at them, you might think, “Monarch butterflies aren’t going anywhere fast.” But each year, these beauties complete one of the most remarkable migrations in the animal kingdom, soaring more than a mile high to gather on a few mountaintops in Mexico they’ve never seen before, yet somehow they all know where to find. We unlock the secret lives of monarchs, and learn how to support them on the...
Bonus Ep: Cult of True Womanhood 26.08.2020 36:51
Bonus Episode | This week, we wanted to share “And Nothing Less,” the new short series from our colleagues at the National Park Service and PRX. It gives a much-needed closer look at the twisty history of the 19th Amendment - and its lesser-known heroes. It’s hosted by two fabulous women: Rosario Dawson and Retta. We’ll play the first episode right here, and you can find the rest of the series by...
The Riverkeeper 19.08.2020 24:55
Fred Tutman is the voice of the river. Specifically, Maryland’s Patuxent River. As the Riverkeeper, his job is to protect and preserve all 110 miles of that waterway – a role that takes him both to the courtroom and to the riverbank. But Fred is also the only African American Riverkeeper in the United States, a fact he sees as an indicator of an environmental movement that is incomplete. And it’s...
Votes for Hawaiians 05.08.2020 31:50
100 years ago this month, the 19th Amendment was ratified into the American Constitution. It’s widely remembered as the moment American women gained the right to vote, but history tells a more complex story. For millions of Indigenous Americans living in far-flung territories, the 19th Amendment afforded some rights – but fell well short of what was promised. So this time: how women’s suffrage cam...
Apollo 12's Really Close Call 22.07.2020 28:26
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...
Take Who Out to the Ball Game? 08.07.2020 29:04
Baseball fan or not, you know this song…or at least, you think you do. “Take Me Out to the Ball Game” is one of the top three most recognizable songs in the country, next to the “The Star Spangled Banner” and “Happy Birthday.” But long-forgotten lyrics reveal a feminist message buried amid the peanuts and cracker jack.
Shredding Skateboarding’s Glass Ceiling 24.06.2020 30:23
When Mimi Knoop entered her first skateboarding competition at 24 years old, she never anticipated leaving her mark on the sport forever. But in the early 2000s, she formed an alliance with pioneering skateboarder Cara-Beth Burnside to make a simple request: that the X Games – and the rest of the skateboarding industry – treat female skateboarders the same way they treat their male peers.
America’s Unknown Celebrity Chef 10.06.2020 32:27
When Lena Richard cooked her first chicken on television, she beat Julia Child to the screen by over a decade. At a time when most African American women cooks worked behind swinging kitchen doors, Richard claimed her place as a culinary authority, broadcasting in the living rooms of New Orleans’s elite white families. She was an entrepreneur, educator, author, and an icon – and her legacy lives o...
Young Harriet 27.05.2020 26:39
In 2017, a photograph of Harriet Tubman surfaced that had been lost to history for more than a century. In a feature of the National Portrait Gallery’s Portraits podcast, we hear the story behind this picture, and how its discovery changes the way we see Tubman – not just an icon of freedom and human dignity, but a courageous young woman.
The People's Insect 13.05.2020 27:21
To look at them, you might think, “Monarch butterflies aren’t going anywhere fast.” But each year, these beauties complete one of the most remarkable migrations in the animal kingdom, soaring more than a mile high to gather on a few mountaintops in Mexico they’ve never seen before, yet somehow they all know where to find. We unlock the secrets lives of monarchs, and learn how to support them on th...
Best of the Rest II 29.04.2020 32:03
A perplexing tattoo. Ancient erotica. Killer bees on the loose. This episode is full of short stories we’ve been eager to tell, but couldn’t… until now. It’s Sidedoor’s second-ever “Best of the Rest!” Learn more about the Freer & Sackler’s collection of shunga, the National Museum of American History’s Great Historic Clock of America on si.edu.
Birds, Birds, Birds! 15.04.2020 25:53
Three billion birds have gone missing since 1970. And conservation biologist Pete Marra considers it his life’s work to make sure more don’t slip away without a fight. In this episode, we go bird-spotting with Pete, and learn what each of us can do to bring birds back.
The Milkmaid Spy 01.04.2020 28:36
Virginia Hall dreamed of being America’s first female ambassador. Instead, she became a spy. Joining the ranks of the U.S.’s first civilian spy network, she operated alone in occupied France, where she built French Resistance networks, delivered critical intelligence, and sold cheese to the enemy. All on one leg.
The Last Man To Know It All 18.03.2020 27:49
Alexander von Humboldt might not be a name you know, but you can bet you know his ideas. Back when the United States were a wee collection of colonies huddled on the eastern seaboard, colonists found the wilderness surrounding them *scary. *It took a zealous Prussian explorer with a thing for barometers to show the colonists what they couldn’t see: a global ecosystem, and their own place in nature...
Outer Space & Underwear 04.03.2020 28:36
In the Venn diagram of life, it’s hard to imagine what spacecraft and women’s underwear might have in common. And that’s probably what NASA engineers thought back in 1962 when they asked a handful of companies to design a spacesuit that would keep a man alive and mobile on the moon. Nobody counted on the International Latex Corporation, whose commercial brand, Playtex, was known for its bras and g...
We're Back! 26.02.2020 2:25
Get ready for season five! Our new season begins on Wednesday, March 4th. Journey with Lizzie through our many side doors for a behind-the scenes view of the Smithsonian.
Cars, Stars, and Rock 'n' Roll 22.01.2020 29:18
Smithsonian Secretary Lonnie G. Bunch III is no administrative assistant. He’s the head of the largest museum, education, and research complex in the world. He’s also the first historian to lead the Smithsonian. In our season finale, we talk with Secretary Bunch about two stories of people overcoming tremendous obstacles to make a change and explore what the past can teach us about today…and tomor...
Ponzi's Scheme 08.01.2020 28:57
Nearly 100 years ago, Charles Ponzi stumbled across a loophole in the international postal system and turned it into one of the most infamous scams of all time. This time on Sidedoor, we follow Ponzi from his early days until his epic downfall, and hear from a postal investigator trained to catch swindlers like Ponzi who continue to use the U.S. mail for nefarious purposes.
The Worst Video Game Ever? 25.12.2019 26:35
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...
Finding Cleopatra 11.12.2019 26:51
Edmonia Lewis was the first American woman of color to achieve international fame as a sculptor. Her 3,000-pound masterwork, “The Death of Cleopatra,” commemorated another powerful woman who broke with convention… and then the sculpture disappeared. On this episode of Sidedoor, we find them both.
