Oddlets from Hungary.
In 1847, Ignaz Semmelweis figured out that doctors were carrying death on their hands from autopsy room to delivery ward. He made them wash. The death rate dropped from eighteen percent to under two. The medical establishment called it an insult, not science. They dismissed him, committed him to an asylum, and when he tried to leave, guards beat him. He died two weeks later of septicemia — a hand infection. The same disease, in the same place, he'd tried to stop.
