Mysteries at the Monument: Chrysler Building, Stanford Mausoleum, Hedy Lamarr

The Chrysler Building is one of Manhattan's most iconic skyscrapers. But its construction was fueled by a bitter rivalry between two one-time colleagues in a competition that transfixed the nation. A mausoleum on the campus of California's Stanford University commemorates one of this school's founding figures, whose chilling murder remains unsolved to this day. And in Hollywood, California, a star commemorates an iconic legend who graced the silver screen with her beauty and the world with a technological innovation that is still in use.
