“Had superconductivity been discovered in the 19th century, Edison might have won the day vs Westinghouse and Tesla.”
Tesla worked for Edison who rejected Tesla’s AC power as splendid but impractical. Tesla quit and set up his own lab.
Due to lack of funds, he sold out to Westinghouse.
I know Tesla originally worked for Edison, but I recall him also working for Westinghouse before Westinghouse bought out his patents.
