The "Soap Lady" is a nickname given to a well-preserved mummy found in the 19th century in a cemetery in New Orleans. Her body was discovered in a crypt and is notable for its unique preservation, which is attributed to the high humidity and specific conditions of the burial site. The mummy is believed to be a woman who died in the early 1800s. The Soap Lady's skin has a waxy appearance, resembling soap, due to the process of saponification. This occurs when body fat is converted into a soap-like substance, often in anaerobic conditions. The mummy is now part of the collection at the Mardi Gras Museum in New Orleans, attracting interest from both tourists and researchers.
