@DensetsuNoGomez Do you know about Thomas Midgley Jr?
@DensetsuNoGomez Dude was a chemist who is responsible both for leaded gas and freon refrigerant.
He was, by all accounts, a very good chemist.
He just happened to develop two things which later turned out to cause planetary-scale ecological damage.
@starkatt
I'm not familiar with him, actually!
