When people ask me what my favorite episode of 99% Invisible is, I have a hard time answering. Not because they’re all my precious little babies or some such nonsense, but mostly it’s because I just can’t remember them all and there’s no simple criteria to judge them against each other. But the show is definitely in contention for the best episode we’ve ever made. It just has everything– engaging storytellers, brilliant reporting, and a compelling history of a moment when the world really changed. It’s called the Freedom House Ambulance Service. It originally aired in the summer of 2020, when a lot of the fundamental aspects of work, life, health, law enforcement, structural racism, cities were all being questioned by more and more people because of COVID and the George Floyd protests. Kevin Hazzard, who reported the piece, subsequently released a whole book on the Freedom House Ambulance Service  called American Sirens: The Incredible Story of the Black Men Who Became America's First Paramedics. It’s new, it’s out now, you should buy it. should read it, it should be on all your Christmas lists. To celebrate the book’s release, I’m proud to re-present to you: The remarkable story of the Freedom House Ambulance Service.
