Who was the madam that ran the Arlington Mansion, known for offering a sex circus for an additional fee?

The correct answer is Josie Arlington, who was a notable figure in New Orleans' history. She ran the Arlington Mansion in the late 19th century and was known for operating a high-profile brothel. The mansion became infamous for its lavish and extravagant offerings, which included what was termed a "sex circus," showcasing a variety of performances and erotic entertainment for her clientele. This reputation contributed significantly to the allure and notoriety of the Arlington Mansion in the context of New Orleans' colorful and often scandalous past.

Henriette DeLille is remembered for her religious contributions and founding the Sisters of the Holy Family, which is unrelated to the context of entertainment or brothel management. Margaret Haugherty was known for her role in operating a different establishment and is often remembered in connection with other aspects of the city's history but not with the Arlington Mansion specifically. Tennessee Williams, while an iconic playwright associated with New Orleans, did not play a role in the world of brothels or the scandalous entertainment scene that Josie Arlington was involved with.
