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.
funfact: though Elon Musk has a company named after Tesla, in an interview, he has said Edison is the better role model. e.g. It's not that Edison invented a light bulb - he created the first power grid. It's like inventing an internet client, and the internet.
Internet client?
