From the company wiki: "The chain was founded in 1906 in the Pittsburgh suburb of McKeesport, Pennsylvania, by George Clinton Murphy. Murphy had gotten his start in retail as a manager of a McCrory's store in 1896. Murphy later moved to Detroit, Michigan, to manage several stores there, and then returned to the Pittsburgh, Pennsylvania, area to launch his own stores. His namesake chain was founded in 1906. It was one of several large retailers to originate in Pennsylvania."
