St. Elizabeths Hospital Tested a Piece of Mussolini's Brain for Dementia. Then, They Lost It

After Benito Mussolini's execution in 1945, American psychiatrist Dr. Winfred Overholser of St. Elizabeth's psychiatric hospital had a hunch that some medical condition might have to been to blame for the dictator's extreme behavior. So he had samples of his brain sent to Washington, D.C., so that he could examine them. And then, one of the samples went missing.
