How do you stop being so afraid? Tracy Twombly had such a strong phobia of spiders, it was messing with her life — stressing her out while she was working at her native plant nursery or hiking through the woods. So, she embarked on a journey to make peace with her eight-legged neighbors (even the extra hairy ones).

In 1935, a diver searching Lake Champlain found something extraordinary: a nearly intact warship from the American Revolution. It was the Gunboat Philadelphia. In this episode, we dive into the story of how a ragtag American army built a fleet of ships to stand up against the British Navy in 1776 ... and lost. But that loss changed the course of U.S. history. 

So, how did Benedict Arnold and a bunch of sailors who had never bee...

In the 1880s, a conservator at the Smithsonian set out for Montana to capture an American bison before the dwindling species vanished forever. He returned with six taxidermied bison that he displayed in the museum. 

The bison diorama wowed visitors so much that it helped kickstart a movement to save the species. But then, just like that, the stuffed bison vanished! 

Where did they go?

Smithsonian Secretary Lonnie G. Bunch III has spent a lifetime thinking about how history gets told. Before becoming the head of the Smithsonian, he was a curator, someone whose job is deciding which stories, people, and objects help us make sense of ourselves. So as America approaches its 250th birthday, Lizzie wanted to know: if you had to tell the story of the United States through just a handful of things, where would you begin...

A screw. A stuffed possum. A shoe-sizing device. What could any of these objects possibly tell us about the history of the United States?

When we think of historic artifacts, we tend to picture the extraordinary: Abraham Lincoln's pocket watch, the original Kermit the Frog, Martin Luther King Jr.'s draft of the "I Have a Dream" speech. But the story of America can just as easily be found in the everyday objects that shape our lives.

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. Why did these men leave behind steamer tr...

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!)

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 effor...

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 History.

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 this vexillological tall tale to f...

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 unspool the strange, unresolved story of a ...

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—are made.

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 everything astronomers expected t...

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.

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. Through rare archival recordings ...
