Mütter museum in Philadelphia, Pennsylvania.
Over 25,00 specimens inhabit the Mütter museum, showcasing human mutations, injuries, and abnormalities. Thomas Mütter, a surgeon, collected abnormal and unique specimens in an effort to show his students the wide variety in human bodies. He donated his collection of 1,300 anatomical and pathological materials to a museum that opened in 1863.
Included here is a 70-pound ovarian cyst, skulls affected by syphilis, a stone fetus, and more. All of these existed inside living, breathing humans, as you see them, testaments to the fragility of humans and their development.
