4. Leonardo da Vinci
The ultimate “Renaissance Man,” Leonardo da Vinci was an artist, scientist, writer, botanist, musician, polymath, inventor, you name it, he could do it. Even if you can’t name it, he could probably do it. He painted masterpieces such as The Mona Lisa and The Last Supper. His enigmatic notebooks, which are sometimes written backward, contain drawings of things like prototype helicopters and anatomical depictions of humans. He is widely regarded to be one of the most widely-talented people who ever lived.
