"I wake up every morning in a house built by slaves." After Michelle Obama said those words at the 2016 Democratic National Convention, thousands of Americans flooded the White House Historical Association with calls. Who were the enslaved African Americans who built the White House? This led historians from the Smithsonian's National Museum of African American History and Culture and the White House Historical Association on a years-long journey that turned up some interesting answers and even bigger questions.  Guests:  Lina Mann, historian, the White House Historical Association Mary Elliott, curator of American slavery, Smithsonian's National Museum of African American History and Culture  

The Smithsonian Institution was founded on principles of reason and scientific inquiry. So why is the museum 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 the floorboards of the museum's attics, 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 Manager, Division of Political and Military History at the Smithsonian’s National Museum of American History Pamela Henson, Institutional Historian at the Smithsonian Libraries and Archives Cpl. Ronald Howlin, Security Officer at the Smithsonian Environmental Research Center Deborah Hull-Walski, Collections Manager, Education Collections at the Smithsonian’s National Museum of Natural History Melissa Johnson, daughter of Deb Hull-Walski and former skeptical teenager Kim Dixon, former volunteer at the Smithsonian’s National Zoo

Eating meat is what made us human. At least, that's one of the leading theories to explain how our brains got so big. The theory says that our human ancestors evolved bigger brains as a result of switching from a plant-based to a nutrient-rich meat diet. But earlier this year a Smithsonian researcher discovered that this theory may not have as much meat on its bones as previously believed. Guests: Briana Pobiner, paleoanthropologist; research scientist and museum educator with the Human Origins Program at the Smithsonian's National Museum of Natural History Becky Malinsky, curator of primates, Smithsonian's National Zoo and Conservation Biology Institute Andrew Barr, paleoanthropologist; assistant professor of anthropology, The George Washington University

When LOL just isn't enough to respond to a friend's killer joke, emoji are there for you. But for many people, there isn't an emoji to represent them or the things they want to say. This has pushed activists, designers, and straight up regular folks to create their own emoji. It's not as easy an undertaking as you might think, but every now and then one of these new emoji is so innovative it breaks the digital mold and finds itself in the Cooper Hewitt, Smithsonian Design Museum. In this episode of Sidedoor, we explore how one groundbreaking emoji is changing digital representation and the future of museum collections. Guests: Jennifer 8 Lee, Founder of EmojiNation Andrea Lipps, Contemporary Design Curator at Cooper Hewitt Smithsonian Design Museum Evan Bonnstetter, Director of Product Policy for Tinder Keith Broni, Deputy Emoji Officer for Emojipedia

Dorothy Liebes was a whirlwind in the weaving world. Throughout the 1930s, she spun luxury fabrics so bold and colorful that their style could only be described as the "Liebes Look." But when the United States entered World War II, she wondered how an artist like herself could be helpful at a time when “there would be no need for luxuries.” What she didn’t know was that wartime would bring an opportunity to put her weaving skills to work in an entirely new way. Joining forces with the American Red Cross, she brought professional artists to the bedsides of wounded soldiers - with results that surpassed Dynamo Dot's wildest expectations.   Guests: Alexa Griffith, manager of content and curriculum at the Cooper Hewitt Smithsonian Design Museum Susan Brown, acting head of textiles at the Cooper Hewitt Smithsonian Design Museum

In 19th century Japan, two sumo wrestlers faced down dozens of firefighters in a brawl so epic it inspired a Kabuki play. But the story of what really happened —and who the heroes are— is all a matter of perspective. Underdogs, antiheroes and villains. How do we decide who plays what role? Guests: Kit Brooks, Japan Foundation Assistant Curator of Japanese Art at the Smithsonian's National Museum of Asian Art Frank Feltens, Japan Foundation Associate Curator of Japanese Art at the Smithsonian's National Museum of Asian Art

"This is a war not only for the territory. This is war against our culture," says Ihor Poshyvailo, director of the Maidan Museum in Kiev, Ukraine. Ukraine has scores of museums, cemeteries, archeological sites, and places of worship where Ukrainian history and national identity are memorialized. But when bombs are exploding, who’s pulling a sculpture from the rubble? Enter the Smithsonian Cultural Rescue Initiative: a team flung together by a deadly earthquake in Haiti that grew through trial and discovery into an international network of professionals devoted to protecting the world’s treasures from threats by humankind and mother nature alike. Guests: Hayden Bassett, director of the Cultural Heritage Monitoring Lab at Smithsonian affiliate Virginia Museum of Natural History Olsen Jean Julien, project director of the Cultural Conservation Center at Quisqueya University in Haiti Cori Wegener, director of the Smithsonian Cultural Rescue Initiative Richard Kurin, Smithsonian Distinguished Scholar and Ambassador-at-Large, co-founder of the Smithsonian Cultural Rescue Initiative Ihor Poshyvailo, director of the National Museum of the Revolution of Dignity (Maidan Museum) in Kyiv, Ukraine Acknowledgments: The work of the Smithsonian Cultural Rescue Initiative would not be possible without the collaboration of countless partner organizations and collaborators, among them: the US government, including the Cultural Heritage Coordinating Committee, the Departments of State, Defense, Homeland Security and Justice, the FBI, Institute of Peace, FEMA, and the Heritage Emergency National Task Force; agencies of other governments like the Ministry of Culture in Haiti, the State Board of Antiquities and Heritage in Iraq, and the Ministry of Culture in Ukraine; other organizations like UNESCO, the International Centre for the Study of the Preservation and Restoration of Cultural Property, International Council of Museums, the American Association for the Advancement of Science, American Institute of Conservation, the US Committee of the Blue Shield, the Penn Cultural Heritage Center and the University of Pennsylvania Museum, the Virginia Museum of Natural History, the University of Maryland, Prince Claus Fund for Cultural Emergency Response, FOKAL in Haiti, the Mosul Museum, the Heritage Emergency Rescue Initiative, the National Center for Research Restoration, and the Kosciuszko Foundation for Ukraine.

Which came first, the flag or the song? Sidedoor is celebrating this Independence Day with a special bonus episode: the story behind our Star-Spangled Banner. Smithsonian’s National Museum of American History military curator Jennifer Jones explains the origin and meaning behind the national anthem through the tattered piece of wool that lies at the heart of the museum.

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 obsessed.   Guests: Cindy Brown, manager of collections, education, and access at Smithsonian Gardens Joyce Connolly, museum specialist at the Smithsonian’s Archives of American Gardens Abeer Saha, curator of agriculture and engineering at the Smithsonian’s National Museum of American History Sylvia Schmeichel, lead horticulturist at the Smithsonian’s National Museum of Natural History Jeff Schneider, deputy director of Smithsonian Gardens
