#9 – Leonardo da Vinci
The 9th place goes to the undeniably great inventor, visionary, anatomist, and more. Anything Leonardo put his mind to, he would perfect. Without a doubt, he is the greatest inventor that ever lived. To say he was ahead of his time doesn’t even start to define his brilliance. The sniper rifle, the helicopter, the parachute, and the diving suit are just a few of things he is credited for inventing. He also gave us the first precise drawings regarding human anatomy. He earned his spot on this list thanks to over four million searches on Google a month, and having more than 600 books written about him.
