  • 100 Objects #13: The Sand Letters
    Aug 14 2026

    This episode is sponsored by Claude. For problems worth solving, get started with Claude at Claude.ai.

    On his deathbed, President Chester Arthur ordered that all of his personal and professional papers be burned. Three barrels of documents went up in flames. But 23 letters survived, initialed only "J.I.S." Comedian Elliott Kalan joins Roman Mars to tell the story of how a politician who owed so much to a corrupt government system became the one to dismantle it, thanks to one woman: Julia Isabella Sand. It’s the story of how a woman no one had ever heard of helped transform a president few remember, and in the process created the American government as we know it.

    A History of the United States in 100 Objects is a production of 99% Invisible and BBC Studios.

  • 100 Objects #12: "Negro Cloth"
    Aug 7 2026

    In 1821, two Rhode Island brothers went looking for buyers for their woolen fabric, and stumbled into a lucrative, captive market: Southern slave plantations. Roman Mars and historian Seth Rockman trace the strange life of so-called "Negro cloth" — a textile category defined by nothing but who it was worn by. Along the way, they uncover how enslaved people shaped the very cloth used to control them, and how New England manufacturers convinced themselves they were the good guys.
