The Langhorne House is the birthplace of Nancy Langhorne, Viscountess Astor, the first woman seated in the British House of Commons. Her sister Irene married the artist Charles Dana Gibson who immortalized his wife as the "Gibson Girl," the international fashion ideal of the turn of the 20th century. Their father, Chiswell Langhorne, worked in the tobacco industry while in Danville and is credited with developing the tobacco auctioneer's chant at Danville's famous loose-leaf tobacco auctions. A historical marker is located at the corner of Broad and Main Streets. The Langhorne House museum is open Saturdays 2:00-5:00 pm, or by appointment.
