Giovanni Maria Lancisi

Giovanni Maria Lancisi (* October 26, 1654 in Rome, † January 20, 1720 ) was an Italian physician and naturalist.

Lancisi studied medicine at the University of Rome and received his doctorate in med at the age of 18 years to Dr.. He was in 1688 by Pope Innocent XI. appointed as personal physician and served in this capacity also his successors Innocent XII. and Clement XI ..

His scientific achievements include findings on hygiene, which he won, particularly through systematic documentation of epidemiological observations. He had found that fevers, which often led to death, fell sharply, as the marshes were drained around Rome.

He drew in 1717 in his De noxiis paludum effluvis the conclusion that midges and mosquitoes acted as carriers of pathogens, where he " harmful substances" accepted as transmitted agent. He sat down with it in contrast to the former idea that these diseases would be triggered by the effect of mal aria, or " bad air ". His further findings relate to, among other diseases such as influenza, rinderpest and especially on malaria. Other important works are De subitaneis mortibus (1707 ) and De motu cordis et aneurysmatibus (1728).

Together with Luigi Ferdinando Marsigli he published in 1714 a book entitled Dissertatio de Generatione Fungorum .... in which contradict both of the popular since ancient view, mushrooms would arise from putrefaction, the mycelium is an intermediate stage between decaying plants and fungi. They follow a determined stance against the existing since the ancient idea of spontaneous generation.

After Lancisi the septal papillary muscle of the tricuspid valve of the heart - muscle Lancisi is named. The medial longitudinal stria of the corpus callosum ( a fine fiber bundles on the large commissure between the cerebral hemispheres ) is referred to as " nerve Lancisii ".

After Lancisi is named in Sassia in Rome, founded in 1714 Biblioteca Lancisiana in Santo Spirito.
