I've read about this chap before and his story not only makes my heart bleed but it goes to show one thing - some things never change and doctors are as arrogant and stupid now as they were back in the 1800s.
I'm not going to go through specific details, but Semmelweis was a doctor. He noted that pregnant women who got infections did so when they were touched with dirty hands. He started washing his hands and made his staff do the same. Illness and mortality dropped to virtually zero.
He tried for many years to get his peers to do the same thing. But, guess what, because he couldn't 'prove' why it worked they wouldn't do it. They just kept on letting their female patients die.
In the end Semmelweis was committed to a lunatic asylum. Only 14 days later the guards beat him to death. He was only 47 years old.
Later that century, after Pasteur 'proved' his germ theory, the washing of hands became compulsory. Semmelweis had been right.
See, the 'knobs' as Hillwoman puts it, are still in existence today. Much better to let the patients and even doctors die, rather than admit they had been getting something wrong.
I think the lunatics really are in charge of the asylum.
Edited to add - just found this about something now known as the Semmelweis Reflex - ""Mob behavior found among primates and larval hominids on undeveloped planets, in which a discovery of important scientific fact is punished"
That's from the book The Game of Life by Timothy Leary. Quite possibly worth reading
