Delphine LaLaurie, also known as Madame Lalaurie, was a wealthy New Orleans socialite and slave owner; she first moved into the mansion in 1832 with her third husband Dr. Leonard Louis Nicolas LaLaurie, where she hosted many lavish parties. Upon moving into the house, LaLaurie immediately took control of the large number of slaves that were used as servants and began her sadistic and horrid treatment of the enslaved workers.
