The
art and science of medicine is not advanced by consensus. Indeed it is inhibited by it.
"In 1847, he proposed hand washing with chlorinated lime solutions at Vienna General Hospital's First Obstetrical Clinic, where doctors' wards had three times the mortality of midwives' wards.[3] The maternal mortality rate dropped from 18% to less than 2%, and he published a book of his findings, Etiology, Concept and Prophylaxis of Childbed Fever, in 1861.
Despite his research,
Semmelweis's observations conflicted with the established scientific and medical opinions of the time and his ideas were rejected by the medical community. He could offer no theoretical explanation for his findings of reduced mortality due to hand-washing, and some doctors were offended at the suggestion that they should wash their hands and mocked him for it."
It was decades and countless lives lost, before his ideas and findings began to be accepted
