How America's Most Powerful City Quietly Lost Everything: Philadelphia, Pennsylvania

Philadelphia was once the largest city in America and the seat of the largest corporation in the world. This documentary traces the full arc — from William Penn's 1682 founding and his grid of tree-named streets, through the industrial golden age that made Philadelphia the Workshop of the World, to the quiet accumulation of closures that hollowed it out. Along the way: the Baldwin Locomotive Works producing 2,600 engines a year with 18,000 workers on Broad Street, the Stetson hat factory employing 5,000 on a nine-acre campus in Kensington, the Cramp shipyard launching battleships for the U.S. Navy, the Pennsylvania Railroad running the country from a Frank Furness–designed terminal, City Hall's thirty-year construction and the gentlemen's agreement that kept every building below William Penn's hat, the Bellevue-Stratford Hotel hosting fifteen presidents, and the Wanamaker Grand Court Organ — still the largest playable pipe organ in the world — filling a seven-story marble atrium with the sound of three orchestras. It is a story about what American cities built, what they lost, and what remains when the factories go silent and the grand hotels change hands.
