In the middle of the 19th century, almost one in three women who gave birth died of puerperal fever. The Hungarian doctor Ignaz Philipp Semmelweis also observed these terrible occurrences in his clinic in Vienna. He came to the conclusion that it was primarily the unhygienic conditions in the clinic itself that led to this disease, as his colleagues were constantly shuttling back and forth between the anatomy department and the delivery room. He tries to convince the doctors of the absolute necessity of thorough disinfection by washing their hands with chlorinated lime. He meets with fierce resistance from his colleagues until he himself sets up an exemplary clinic in Budapest.
