"The Etiology, Concept, and Prophylaxis of Childbed Fever" was published by Semmelweis in 1859-61 in German. An English version was published by the University of Wisonsin Press, Madison, Wisc. in 1983. Translated and edited by Codell Carter, Carter also provided an Introduction.
For an opinion that Semmelweis "was in fact beaten to death" while trying to escape from the asylum, see p.58 of the Translator's Introduction.
