The Most Mysterious People in History

Some people slipped through the one thing we assume can never be lost — their own name. A prisoner spent 34 years masked so no one could ever see his face. A boy walked out of a dark cell into a German town, spoke of a life no human should survive, and was murdered before anyone learned who he was. The true inventor of the movie camera vanished off a train weeks before he could prove it. And the most kissed face in the world belongs to a drowned woman nobody could identify. These are the most mysterious people in history — real, documented, seen by thousands — and yet we still don't know who they truly were. We uncover the Man in the Iron Mask, Kaspar Hauser, Louis Le Prince, the Isdal Woman, the Boy in the Box, D.B. Cooper, the Babushka Lady, and the Woman of the Seine. History remembers them perfectly, in every detail but the one that mattered most — who they actually were.
