Here’s Dr. Douglas Owsley, a forensic anthropologist at the Smithsonian National Museum of Natural History, giving a talk at the Clara Barton Missing Soldiers’ Office Museum on the examination and interpretation of Civil War soldier remains and how those investigations give us a better understanding of historical events. This is a fascinating talk.
The video’s description tells us, “Forensic anthropologist Douglas Owsley gave an illustrated talk on his work with Civil War remains, including excavations from the Gettysburg and Manassas battlefields, as well as from the H.L. Hunley, a Confederate submarine that sank just off Charleston, South Carolina. Mr. Owsley is the head of Biological Anthropology at the Smithsonian National Museum of Natural History. This event took place at the Clara Barton Missing Soldiers Office Museum.”

This is a great technical talk well presented to a general audience.
The modern anthropologist has a tremendous tool kit for exploring the unknown.
