National Museum of Health and Medicine

"The Army Medical Museum has evolved over time, and is now the National Museum of Health and Medicine in Silver Spring, Maryland. The museum maintains sizeable collections, still including the original Civil War collections. In addition to Guiteau’s brain, which was part of a 2013 exhibit on brains, it holds a great deal of paperwork on the assassination (such as the original autopsy) as well as specimens related to Lincoln’s killing. The museum’s core mission remains the same as it was in 1862: gather specimens for the dual purposes of training medical professionals in successful treatment methods and curating exhibits for the public."
