In 1861 a guy named Semmelweis published the findings from a study he performed. He required medical students and doctors to wash their hands in chlorinated water before attending delivery of babies. The mortality rate of women cared for by these providers dropped from 18% to 2%.
His theory of transmissible disease carried on the hands of doctors was dismissed by colleagues. He was comitted to an asylum, beaten by the guards, and died of sepsis weeks later.
RFK is those fucking guys.
