Mad Scientists Through the Ages

OK, we've had enough of this good science gravitational wave stuff.  Now for some bad science.  Here's a list of fifteen mad scientists spanning from ancient times through the 19th Century.

Now, I have seen plenty of enraged scientists and several slightly eccentric scientists, but those were more of personal affairs.  The quality of their research didn't suffer though the quantity occasionally might.  The classic weird old dude in a castle seems to be creature of the past, when proto-science was the best horse running.  One might mourn that the world is a less colorful place for the lack of true mad scientists, but honestly, the real stuff we're doing these days is far more interesting and arguably even more bizarre.
