Louise was the daughter of the architect Alexandre-Théodore Brongniart (1739-1813),
famous for designing the Stock Exchange building in Paris
and transforming the Père Lachaise Cemetery.
Thanks to his mother who was a painter and
his father who was a caretaker at the Louvre museum,
Brongniart became acquainted at a very early age with the best sculptors of his time.
In 1777, he commissioned one such sculptor, Jean-Antoine Houdon (1741-1828),
(considered by many to be the most brilliant portraitist of the 18th century)
to sculpt in stone the portrait of his daughter, Louise.
