This is a good write-up about Semmelweis' findings - it has some points which I was not previously aware of.
"The Semmelweis reflex or "Semmelweis effect" is a metaphor for the reflex-like tendency to reject new evidence or new knowledge because it contradicts established norms, beliefs or paradigms."
- https://en.wikipedia.org/wiki/Semmelweis_reflex
The phenomenon of rejecting advancements is pervasive throughout medicine, even today.
