Ignaz Semmelweis Ignaz Philipp Semmelweis (; hu, Semmelweis Ignác Fülöp ; 1 July 1818 – 13 August 1865) was a Hungarian physician and scientist, who was an early pioneer of antiseptic procedures. Described as the "saviour of mothers", he discovered that t ...

, a Hungarian physician who discovered in 1847 that childbed fever mortality rates fell ten-fold when doctors disinfected their hands with a chlorine solution before moving from one patient to another, or, most particularly, after an autopsy. (At one of the two maternity wards at the university hospital where Semmelweis worked, physicians performed autopsies on every deceased patient.) Semmelweis's procedure saved many lives by stopping the ongoing contamination of patients (mostly pregnant women) with what he termed "cadaverous particles", twenty years before

was discovered. Despite the overwhelming empirical evidence, his fellow doctors rejected his hand-washing suggestions, often for non-medical reasons. For instance, some doctors refused to believe that a gentleman's hands could transmit disease. In 1865, most likely because of the offense many so-called peers felt, János Balassa wrote a document referring Semmelweis to a mental institution. On 30 July, Ferdinand Ritter von Hebra lured him, under the pretense of visiting one of Hebra's "new Institutes", to a Viennese insane asylum located in Lazarettgasse (Landes-Irren-Anstalt in der Lazarettgasse). Semmelweis surmised what was happening and tried to leave. He was severely beaten by several guards, secured in a straitjacket, and confined to a darkened cell. Apart from the straitjacket, treatments at the mental institution included dousing with cold water and administering castor oil, a laxative. Treatments there, most likely as a response to his many letters condemning other contemporary doctors for unhygienic practices, were especially cruel. He died after two weeks, on 13 August 1865, aged 47, from a gangrenous wound, due to an infection on his right hand which might have been caused by the beatings, and the lack of disinfection and clean-up of any wounds received at the mental asylum. While there is uncertainty regarding its origin and generally accepted use, the expression "Semmelweis Reflex" had been used by the author
