Ok, what was the name of the guy from the 1800's (or 1900's?). He worked in a hospital I think, for delivering babies. The hospital had a high death toll and many women died because the doctors who were delivering the babies did not wash their hands. So this guy told them to wash their hands and the death toll fell a lot.
ETA - NVM, it just popped in my head right now. It was ignaz semmelweis.
Alright let me add a question. Are you lonely right now? I am :(
