Louise Evelina du Pont (1877-1958) was the daughter of Mr. and Mrs. Henry Algernon du Pont. In 1922 Henry A. du Pont purchased the original family home, Eleutherian Mills, for his daughter who, with her husband, began restoring the house and building a Renaissance garden adjoining it. This collection consists of twelve black and white photographs of Louise and Frank Crowninshield's garden at Eleutherian Mills, apparently taken by Horace Dugdale during a visit, circa 1938. Also two photographs of the abandon Hagley House which stood nearby.

Louise du Pont Crowninshield (1877-1958) was an early leader in the field of historic preservation and a collector of antiques and hooked rugs. The collection includes her papers as well as those of her husband Francis Boardman Crowninshield, her mother, and other family members.

Louise Evelina du Pont (1877-1958) was an heiress and preservationist, who was the great granddaughter of Eleuthère Irénée du Pont (1771–1834), the founder of E. I. du Pont de Nemours and Company. She was the last du Pont to live on the Eleutherian Mills estate. This collection consists of photographic and graphic materials primarily of Crowninshield's extended du Pont family and friends. The collection has been organized into four series: Family portraits, Travel photographs, Residences, and Mary Pauline Foster du Pont sketches and collection of travel souveniers.
