Winterthur, an American country estate, is the former home of Henry Francis du Pont (1880-1969), an avid antiques collector and horticulturist. In the early 20th century, H. F. du Pont and his father, Henry Algernon du Pont, designed Winterthur in the spirit of 18th- and 19th-century European country houses.
