The Mütter Museum gets its name from Dr. Thomas Dent Mütter who, in 1858, donated the original collection of medical artifacts.

Mütter's purpose for donating his personal collection was to create a place for biomedical research and education.

But over the years, the Mütter Muesum has opened its doors to the public as its collection has grown.

This nine-foot-long human colon is one of the most popular attractions at the Mütter Museum. It contained at least 40 pounds of feces when it was removed from the body of a circus performer known as the Human Balloon.

The Mütter Museum even has pieces of Albert Einstein's brain that are divided onto microscope slides.

Even though it seems like the creepiest place on Earth, the Mütter Museum welcomes over 130,000 visitors every year.
