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. Guests: Sonia Purnell , author of “A Woman of No Importance: the Untold Story of the American Spy who Helped Win World War II.” Randy Burkett , CIA Staff Historian Christina Gebhard , m...
Jan 03, 2024•29 min•Transcript available on Metacast It’s a song we often hear at the start of the new year. But what does “auld lang syne” even mean? And how did it come to be associated with New Year's Eve? With a little musical sleuthing, we find Charlie Chaplin might have something to do with it… Guests: James Deutsch , curator of folklife and popular culture at the Smithsonian Center for Folklife and Cultural Heritage...

Dec 06, 2023•26 min•Transcript available on Metacast When Maggie Kuhn was forced to retire from the job she loved at age 65, her colleagues gave her a sewing machine as a parting gift. Outraged, she shut the sewing machine in a closet and, instead, stitched together the first-ever movement against ageism in the U.S. The Gray Panthers would galvanize gray haired citizenry and youth alike to challenge the way Americans think about aging. Guests : Katherine Ott , curator and historian in the Division of Medicine and Science at the Smithsonian's Natio...

Nov 08, 2023•29 min•Transcript available on Metacast The Smithsonian Institution was founded on principles of reason and scientific inquiry. So why is the Smithsonian home to countless tales of unexplained phenomena and—dare we say—ghost sightings? Inspired by an apparition at the National Museum of American History, we creak across museum attic floorboards, sneak into an old house in the woods, and even travel back in time to bring you a collection of spooky stories that can only be found at the Smithsonian. Guests: Molly Horrocks , Collections M...
Oct 25, 2023•38 min•Transcript available on Metacast Looks like these criminals used correct postage, 'cause justice is about to be delivered. Okay, there are no snappy one-liners in this crime scene investigation, but there are explosions, collisions, manhunts and even a cow who was in the wrong place at the wrong time. On the centennial of "The Last Great Train Robbery," we re-examine the evidence to find out how U.S. Postal Inspectors tracked down a band of old school outlaws using cutting edge criminal forensics...and postmarked them for priso...

Sep 27, 2023•28 min•Transcript available on Metacast Icky Gunk. Moldy Hay. Kermit. You might recognize one of these names. Before Kermit joined Miss Piggy and Big Bird, he was kicking it with Sam and Friends — a local tv show in Washington, D.C. that launched Jim Henson's career. We journey back to 1955 to figure out how this eccentric cast of puppets built the foundation for everything Jim Henson would do afterwards, from Sesame Street, to The Muppet Show and even Labyrinth (we see you, David Bowie fans). And we venture into the conservation labs...

Sep 06, 2023•2 min•Transcript available on Metacast 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, retracing the route from Missouri to California over four and half months. This guest episode of the Outside p...
Aug 30, 2023•30 min•Transcript available on Metacast 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.

In honor of the Smithsonian’s 177th birthday, we’re sharing one of our favorite stories from the Sidedoor collection. Guests: William Bennett, conservator at the Smithsonian Insti...

Jul 19, 2023•14 min•Transcript available on Metacast 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 physiognotrace, leaving behind a ledger book that gives us a rare glimpse of early America. A ledger book…laced with po...
Jul 05, 2023•33 min•Transcript available on Metacast America has a long history of clustering heavy industry and toxic facilities in communities where people of color live.

Folkways Recordings —as it's now known— lives on within the Smithsonian, connecting the past, present and future… through sounds. Guests: Michael Asch, anthropologist and son of Moses Asch Jake Blo...
Jun 07, 2023•36 min•Transcript available on Metacast Women have long fueled America's greatest scientific achievements. But when you go searching for information about these women scientists, you'll likely come up short. Only 19% of articles on Wikipedia are about women. In the field of science, this difference is even more pronounced. But now, a team at the Smithsonian is using artificial intelligence and good old fashioned research skills to scour the archives for lost women of science and publish their stories … before it’s too late. Guests: Li...
May 24, 2023•28 min•Transcript available on Metacast Nowhere in the world are lawns as revered as they are in the United States. The picture-perfect patch of grass is so deeply rooted in the American psyche it feels more like a default setting than a choice. Americans spend countless hours every year seeding, watering, mowing, and fertilizing patches of grass that don't make much sense, economically or ecologically. But why? In this episode, we dig into the history of our lawnly love to learn where the concept came from...and how we grew so obsess...

Apr 26, 2023•26 min•Transcript available on Metacast Until the 1970s, women were barred from competing in U.S. marathons because of the belief that the "violent movements" would wreak havoc on their reproductive system, "thus defeating a woman’s true purpose in life, i.e., the bringing forth of strong children." Through a series of steps, stumbles —and one epic tackle— running pioneers like Roberta "Bobbi" Gibb and Kathrine Switzer blazed the trail for women marathoners who followed, including Sunita Williams — the first person to run the Boston M...
Apr 12, 2023•33 min•Transcript available on Metacast We think of paintings as art, but can they also be a source of data? 300 years ago, a young prince inherited the throne in Udaipur, India, and brought with him some newfangled ideas about art. His court artists created massive paintings that flew in the face of convention, documenting real life events, times, places and even emotions —especially during the annual monsoon season. These paintings are so detailed that - centuries later - they can serve as archival records to help understand our own...
Mar 29, 2023•29 min•Transcript available on Metacast Most people in North America can't see the Milky Way. The reason? We're ensconced in a luminous fog of artificial lighting 24/7. The evolution of lighting technology over the last century has made it possible to live, work, and play at any hour - day or night. But light pollution affects all life on earth, from humans to plants and insects. So, how did we find ourselves surrounded by a glowing shroud of electricity... and can we have the dark, without giving up the light? Guests: Hal Wallace , c...

Feb 09, 2023•14 min•Transcript available on Metacast In 1983, the Cabbage Patch Kids were released, causing widespread pandemonium in toy stores and in the media. How did a children's toy inspire such bad adult behavior? Slate’s Decoder Ring podcast explores the strange world of the Cabbage Patch Kids to figure out why they hit it so big. The answer involves butt tattoos, slightly grotesque faces, industrial innovations, an origin story in a cabbage patch, and serious accusations of copyright theft. We’ll be back with new episodes of Sidedoor soon...
