It’s a pretty terrifying thought, to simply vanish without a trace. Imagine the family members worried sick, never knowing for sure what happened. Imagine the investigations, perpetually stalling out because no one has any real clues by which to go on. Every time there seems to be a leader, or a witness who swears he knows the truth, it fizzles and you’re right back at square one.

And amazingly, it’s not just us anonymous, everyday people who go missing, either. Sometimes well known, famous, and notorious people simply disappear without any sign of where they went. Here are some of the most mysterious famous disappearances in history.

12Jimmy Hoffa

Chances are you don’t know the name here, but you no doubt immediately recognize “A dingo ate my baby!” Chamberlain was an infant who vanished from her home in Australia, and her mother was convicted of murder – only to be released when evidence was found supporting her claim that a dingo really did take the child.

9Harold Holt

Again, this is a name you wouldn’t immediately recognize, but Virginia Dare was the first English settler ever born in the New World in 1587. Her father returned to England to try to earn more money for his young family, and when he returned to America, his daughter, and the entire colony – yes, this is the Roanoke colony – was gone.

7Frank Morris

Perhaps the most famous big band leader of all-time, Glenn Miller was leading the US Army Air Force Band and was headed to Paris in 1944, when his plane simply vanished. No evidence of what happened to either the plane or Miller has ever been uncovered.

2Ambrose Bierce

An author and philosopher, Ambrose Bierce was also a veteran of the American Civil War and gained fame as a journalist. His writing led him to Mexico during the revolution led by Pancho Villa, and ultimately, his disappearance in that nation in 1914.

What, did you honestly think we could make this list without including Amelia Earhart? The most famous female pilot of all-time was attempting to cross the Pacific Ocean when her plane went down, and neither the plane nor Earhart was ever found.
