Nikola Tesla was the most popular scientist of the 19th century, more popular than Edison. In fact, Tesla worked with Edison in the 1880s but had a falling out because he believed Edison stole his ideas. Tesla developed AC power used all over the world now and worked with George Westinghouse to promote it. He laid the foundation for radio, TV and many modern inventions. He fell into insanity & became a recluse. He died in poverty in a tiny apt'mnt, by then considered a "mad scientist" in 1943.
