The question "Who is John Galt" is repeatedly throughout AtlasShrugged. Late into the book we learn the John Galt is the man who stopped the motor of the world and the leader of the /Strikers. He is also the same character as /MysteryWorker. There is a clothing store at 193 Gore Creek Drive, Vail Village, Colorado called John Galt Ltd. One presumes that, on occasion, a customer unknowingly walks in and asks, "Who is John Galt."
