Tell me about Ignaz Semmelweis

Ignaz Semmelweis (1818–1865) was a Hungarian physician whose work fundamentally changed medical practice by highlighting the critical importance of hand hygiene [2, 3].

He is best known for discovering the cause of puerperal fever, also referred to as "childbed fever," which was a frequent and deadly infection among women who had recently given birth [1, 3]. While working at a maternity clinic in Vienna, Semmelweis observed that mortality rates were significantly lower in wards where doctors washed their hands with a chlorine solution after performing autopsies and before examining patients [1, 3].

Although he successfully reduced death rates through these antiseptic practices, his findings were not immediately accepted by the medical community of his time [1, 2]. It was only later, with the development of the germ theory of disease by Louis Pasteur and the subsequent work of Joseph Lister, that Semmelweis's observations gained widespread scientific validation and led to the adoption of modern antiseptic methods [2]. Today, he is often remembered as the "Savior of Mothers" for his pioneering contributions to medicine [3].
