Upper Louviers was a residence located on the east bank of the Brandywine Creek in Brandywine Hundred, Delaware, opposite the powder mills of E. I. du Pont de Nemours & Company. It was supposedly built circa 1802 by Peter Bauduy (1769-1833), one of the original partners of E. I. du Pont (1771-1834), and later served as the home of the family of Victor du Pont (1767-1827) from about 1810 to 1833, Admiral Samuel Francis Du Pont (1803-1865) and his wife Sophie Madeleine du Pont (1810-1888) from 1833 to 1888, and Francis I. du Pont (1873-1942) and his children from 1918 to 1984. It was demolished circa 1986.

Elise du Pont Elrick (1902-1984) was an architect and translator. She was the daughter of Francis Irénée du Pont (1873-1942) and Marianna Rhett du Pont (1875-1967). She graduated from the Massachusetts Institute of Technology School of Architecture in 1931. In 1952, she established Delrock Company and formed a partnership with the contractor Hugh Smyth (1885-1965) in Wilmington, Delaware. They designed and built residences throughout the Wilmington area, including the development of Forest Hills. She also specialized in institutional buildings, and one of her designs included the library at the Alva Belmont House in Washington, D.C., then the national headquarters of the National Woman’s Party.
