Twin Peaks has only a small link to Philadelphia, Agent Dale Cooper was from here. However David Lynch has a profound connection to the city, particularly its gritty, dangerous past.
Lynch studied at the Pennsylvania Academy of Fine Art, living in the Callowhill neighborhood in the late 60s. At a time when the neighborhood was still largely industrial and trains still carried commuters atop the Reading Viaduct, Callowhill was another world, one Lynch blames for his dark and disturbing stories.
