The Hungarian people are proud of Ignaz Philipp Semmelweis (1818–1865), born in Pest to a catholic German family, the discoverer of the cause of childbed fever – fatal infectious complications in women in labor, and introduced effective measures of it's prevention in 1846. In his honour, the building where he was born in 1818 now houses a museum of the history of medicine bearing his name, which tells not only about Dr. Semmelweis, but also provides a multifaceted illustration of the main milestones in the development of European and world medicine. The remarkable permanent exhibition is complemented by regularly updated temporary exhibitions.
