You may have heard of Thomas Edison, or at least a few small things he invented. You know, like the first movie camera, the incandescent light bulb, just a few minor things.
Anyway, Edison was close friends with Henry Ford, yes, the same Henry Ford that owned the car company. It is rumored that when Edison was passing away as a result of complications with his diabetes, Henry Ford convinced him to seal his last breathe in a test tube as a memento.
The test tube is stored in the Henry Ford museum. Edison wasn’t alone in having something stored like this. It is rumored that part of Einstein’s brain is being studied in a University in Canada! Learn more about Thomas Edison’s life in the source.
