Semmelweisas
Semmelweis is a surname of German origin. It is most famously associated with Ignaz Semmelweis, a Hungarian physician who is credited with saving countless lives by pioneering antiseptic procedures. In the mid-19th century, while working at the Vienna General Hospital, Semmelweis observed a high mortality rate from puerperal fever, or childbed fever, among women in one of the maternity clinics. He noticed that the mortality rate was significantly lower in the clinic attended by midwives, compared to the one attended by physicians and medical students who also performed autopsies.
Semmelweis hypothesized that "cadaverous particles" were being transferred from the autopsy rooms to the maternity ward,
