Dr Simon Campbell is not technically the guy who invented Viagra, but he co-wrote the research proposal that lead to it. It was originally meant to treat a heart condition called angina, but unfortunately didn’t help that much. Still, it’s aided the sexual health of millions of older men, which is nothing to sneeze at.
