Mütter Museum's 'Soap Lady'

The Mütter Museum at the College of Physicians of Philadelphia houses the 'Soap Lady,' a human cadaver preserved by adipocere (saponification of body fat) that was recovered in 19th‑century Philadelphia. The specimen is a distinctive, long‑displayed example used by the museum to illustrate unusual forms of preservation and pathology. The Mütter is a specialized medical history museum with a collection of unique anatomical and pathological specimens.
