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 whose life and work were changed by it forever.  This episode features recordings from the "Visual Arts and the AIDS Epidemic" Oral History Project produced by the Smithsonian’s Archives of American Art.

In 1621, a group of Pilgrims and Native Americans came together for a meal that many Americans call "The First Thanksgiving." But get this—it wasn't the first, and the meal itself wasn't so special either. The event was actually all but forgotten for hundreds of years…until it was dusted off to bolster the significance of a national holiday. This time on Sidedoor, we talk to Paul Chaat Smith, a curator at the Smithsonian's National Museum of the American Indian, to explore how much of what you think you know about Native Americans may be more fiction than fact.

Inside the Smithsonian’s National Museum of Natural history is the skeleton of Grover Krantz—an accomplished anthropologist, tenured professor…and diehard Bigfoot believer? As the first serious scientist to study the legendary creature, Krantz risked his career and reputation on a subject that many consider a joke. And while the museum remembers him as a man who loved science so much that he donated his body to it, another community remembers Krantz as a pioneer in the study of Sasquatch.

What if you found out that your grandmother’s house was going on display at a museum? The. Whole. House. That’s what happened to the Meggett sisters, who grew up visiting, eating, and playing at their grandma’s tiny cabin in South Carolina, unaware that it was originally built to house enslaved people. This time on Sidedoor, we explore the house's unique journey from slave cabin to family home to its latest incarnation as a centerpiece at the National Museum of African American History and Culture.

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 creatures to ever live on our planet. This time on Sidedoor, we’ll explore our surprising relationship with whales through the lens of one species: the gray whale. Once aggressively hunted and thought to be nearly extinct, they've rebounded to become one of the North Pacific’s most abundant whale species. So, what changed?

Our dear host Tony Cohn is leaving *Sidedoor *to travel the world, so we want to take a minute to introduce you to the new voice of the show, Haleema Shah.

In Washington, D.C., the neighborhood of Anacostia was once dismissed as the wrong side of the river. Now, it is turning into a housing hotspot as the city sees an influx of newer, wealthier residents. It’s called gentrification, and the process has become a flashpoint from Houston to Harlem and beyond. We’ll explore this longtime fight for housing through an innovative community museum that empowers local residents—kids and adults—to tell the stories of these changing neighborhoods.

The world’s deadliest animal isn’t the tiger, the snake, or even the alligator—it’s the mosquito. These tiny insects spread diseases that kill over 700,000 people each year. But what can we do to stop them? In search of solutions, host Tony Cohn travels around Panama with some well-equipped Smithsonian experts on the trail of this bloodthirsty, buzzing beast.

It begins a bit like a *Scooby Doo *episode: archaeologists digging at a place called “Witch Hill” discover mysterious human remains in an ancient trash heap. Who was this person? How’d they get there? Astonishingly, it would take 40 years to find out, and the story is way more surprising — and groundbreaking — than anyone could’ve ever imagined. So, grab your Scooby Snacks and join Sidedoor as we journey to the Smithsonian Tropical Research Institute in Panama to see these unusual bones firsthand and meet the “meddling kids” trying to solve a mystery 700 years in the making.

The Hope Diamond is one of the most iconic items in the Smithsonian's collections, but this glittering gem is rumored to have a dark side. French monarchs, an heiress, and at least one unlucky postman have met misfortune after possessing it—though does that really constitute a curse? This time on Sidedoor, we track the lore of this notorious gem through the centuries, from southern India, through the French Revolution, and across the Atlantic Ocean to its current home at the National Museum of Natural History, to find out for ourselves.
