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 effort that’s also challenging the romanticized imagery popularized by photographers and anthropologists of the ...

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.

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 find out how this myth got started, and who Betsy Ross really was. Sidedoor ...

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 tapir named Alice, and ask what it means to live with uncertainty when ...

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. With the help of Smithsonian curator, Susan Brown, and author, Rachel Slade, we also explore the hi...

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 to see...unless the universe was filled with unseen matter. This is the story...

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 he uncovered in Chinatown shocked Asian Americans across Northern California to stand up and demand justice ...

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?

For years, Katharine, Wilbur and Orville were inseparable — until tragedy and a love affair upended everything. This is the story of the Wright sib...

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 and firsthand stories, we trace Chenier’s journey from a sharecropper’s son t...

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 unlikely defenders working to stop the trade—and care for the reptiles caught in the middle. Because once a tu...

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 creatures may seem slow, but their decline is happening fast. And the scariest part? We barely understand wha...

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 libraries and universities — he championed a philosophy: that it was the duty of the ultra-wealthy to serve the ...
