St. Elizabeths Hospital has had its fair share of infamous patients. Would-be Presidential assassins Richard Lawrence and John Hinckley, silent film actress Mary Fuller, and “The Shotgun Stalker” James Swann have all called the psychiatric hospital home. But the building has also had some lesser-known, but equally significant, guests – or at least parts of them. St. Elizabeths quite literally got a piece of Benito Mussolini’s mind when sections of his brain were sent there for research in 1945.That’s right: as literary great Ezra Pound spent time in the Chestnut Ward, a portion of his fascist idol was just next door. And while Pound left after twelve years, the brain remained, shrouded in obscurity, until its eventual disappearance more than twenty years later.
