Who do you believe was the most underrated scientist to ever live?

Tesla.
His technology was maligned and suppressed.We are only beginning to employ a small fraction of his discoveries and theory.To this day,he is given little to no credit.

@lucillelucillelucille That was my pick as well, he was way ahead of his time. Faraday comes to mind too for me.

Tesla.

Yes, Tesla. And Ignaz Semmelweis.

Tesla. To the fifth power.

I was going to say Tesla as well. I know nothing about him, but every time people talk about underrated scientists, Tesla comes up. :\

Here’s two more: Aristarchus and Copernicus. I think they deserve more credit than Galileo. The heliocentric model of the solar system was their idea first.
