The Wikipedia article kind of suggests he was railroaded due to people not liking his ideas: In 1865, János Balassa wrote a document referring Semmelweis to a mental institution. On July 30, 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).[60] 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. He died after two weeks, on August 13, 1865, aged 47, from a gangrenous wound, due to an infection on his right hand which might have been caused by the struggle. The autopsy gave the cause of death as pyemia—blood poisoning. https://en.m.wikipedia.org/wiki/Ignaz_Semmelweis https://en.m.wikipedia.org/wiki/Ignaz_Semmelweis
