Started in 1858 thanks to a donation from Dr. Thomas Dent Mütter, the museum has collection of the rare, strange, and bizarre specimens that have grown ever since. It has specimen collection of medical oddities, anatomical and pathological specimens, wax models, and antique medical equipments. It is the current home of the Hyrtl Skull Collection, a nine-foot-long human colon, a collection of inside-out babies, and the conjoined liver from the famous Siamese twins Chang and Eng Bunker. `
