Helen Hope Montgomery Scott (April 8, 1904 – January 9, 1995) was a socialite and philanthropist whom Vanity Fair once called "the unofficial queen of Philadelphia's WASP oligarchy." She is most famous as the inspiration for Tracy Lord, the main character in the Philip Barry play The Philadelphia Story, which was made into the film of the same name as well as the musical film High Society. Scott was a longtime chairman and executive director of the Devon Horse Show and sponsored other events to raise money for the Bryn Mawr Hospital, her favorite charity. She was considered the epitome of Main Line high society and symbol of an aristocratic, free-spirited elegance.
