In 1847, seventy slaves went to the Maryland courts to enforce a deed of manumission granting them their freedom. What should have been a simple matter exploded into a nine-year court case that spun furiously around the ominous question at its core: if a man frees his slaves on moral conviction, does that make him insane?

Warren G. Harding, Henry Ford, Thomas Edison, and Harvey Firestone were some of the biggest names of the early 1920s.

Read about the President's camping trip in the summer of 1921.

It's no secret that the CIA sometimes thought more about whether it could and less about whether it should. Project Acoustic Kitty was one of those times. Does "trained cat" sound like an oxymoron to you? It should, but it cost the CIA $15 million to find out the same thing!

Victor Frankenstein wasn't the only scientist to raise the dead! In 1903, Alexander Graham Bell departs for Italy to escort the Smithsonian's founder back to the United States. The only problem? James Smithson has been dead for almost 75 years. How exactly do you declare THAT at customs?

Where can you see lacy Arabic architecture, the tombs of ancient Romans, and artifacts from medieval France? Why, in Washington DC, of course!

The Washington Monument we know today is iconic, but it was never really planned to look that way. Before it grew up, the monument went through many, many proposed designs. After decades in limbo and a construction mired in drama, one engineer's vision triumphed over artists, politicians, and critics.

Mount Vernon is a priceless national treasure and symbol of America's foremost founding father. But were it not for a tiny staff guarding it through the 1860s, it might not have survived the Civil War.
