I’m very biased, but I would remove Edison from your list, and I would add Newton.

All great men and we were lucky to have had them. But Da Vinci seems to have been in a class all his own... From Wiki:

Leonardo di ser Piero da Vinci ... was an Italian polymath of the Renaissance whose areas of interest included science and invention, drawing, painting, sculpture, architecture, music, mathematics, engineering, literature, anatomy, geology, astronomy, botany, paleontology, and cartography. He has been variously called the father of palaeontology, ichnology, and architecture, and is widely considered one of the greatest painters of all time (despite perhaps only 15 of his paintings having survived).

Edison was not an inventor. He was a business man and an innovator, who’s company improved upon other people’s designs.
