The museum, formerly called the Army Medical Museum, is now part of the Armed Forces Institute of Pathology in Washington, D.C. It houses millions of artifacts in a variety of historically significant collections. Selections from their photographic archives have been assembled in a Flickr photostream, which "began as unofficial 'favorite photos' of the staff of the Otis Historical Archives" at the museum.
The subject material is understandably weighted toward anatomic and pathologic specimens, but also includes historical photos re public health and the delivery of health care in war and in peacetime.
