These days it's fashionable to venerate Tesla and denigrate Edison. Tesla's contributions to AC motors and power are great and beyond dispute. The others, not so much. For those who like to denigrate Edison by comparison, I challenge to read "Edison" by Josephson and maintain that opinion. I.e. Tesla transformed AC power, Edison transformed multiple foundational industries.
Here’s an article, a few years ago and also from Smithsonian Magazine, telling of some of Tesla’s disturbing opinions.
For example, advocating forced eugenics to weed out ‘undesirables’ from the human race. He felt that the forced sterilisation of criminals and mentally ill in Nazi Germany didn’t go far enough.
