My dad introduced me to Leonardo's work when I was a kid. We talked about it for hours. Today I'm thinking of both of them.
Their story
Leonardo da Vinci painted the Mona Lisa and The Last Supper and filled thousands of notebook pages with anatomy, flying machines and engineering. He spent his last years as guest of the King of France.
In their own words
“Learning never exhausts the mind.”

This made me cry. Thank you.
