Leonardo Da Vinci, probably the genius of all genius, with an IQ of 220.

He made the greatest inventions like the helicoptor, planes,
ball bearings to overcome friction, weapons, etc.
He also drew great paintings like Mona Lisa and The Last Supper.
Mona Lisa - the one you will staring at, is not staring at you but just behind you.
The Last Supper - 3 years to complete. All the faces are not drawn any old how.
He spent months to observe the people around him so he could capture the best expressions
that is most suitable for the characters in the Last Supper.
