What did Ignas Semmelweiss do?

Answer 1

Ignaz Semmelweis was a Hungarian physician known for his pioneering work in antiseptic procedures. In the 1840s, he discovered that the incidence of puerperal fever (childbed fever) among mothers could be dramatically reduced by requiring medical students to wash their hands with a chlorine solution before delivering babies. His findings emphasized the importance of hygiene in preventing infection, laying the groundwork for modern infection control practices, although his ideas were not widely accepted during his lifetime.
