Nikola Tesla
Inventor
Nikola Tesla is here because he worked from a picture he could already see. The machine came second. I come back to that when I am sketching around a thing I have not actually looked at.
He was born in 1856 in Smiljan, built the alternating-current system that won, and died in New York in 1943 with the later inventions unfinished. The useful part is the finished picture, not the myth.
