7: The Mutter Museum, Pennsylvania
This museum is run by the College of Physicians of Philadelphia and is considered the top museum covering medical history in the country. Here you can find medical instruments, models, and anatomical specimens, all carefully displayed in a setting reminiscent of the 19th-century cabinet museums. Every year, 130,000 visitors come to the museum and there is also a Museum Education program for schools. Some of the most memorable items in this unusual place to visit include Einstein's brain, the tallest skeleton that is on display within North America, and President Grover Cleveland's jaw tumor.
