Giovanni Maria Lancisi

Italian physician

Giovanni Maria Lancisi belongs to the record of natural history as one of those whose work outlasted the questions that prompted it.

Giovanni Maria Lancisi was born at Rome in 1654. He was educated at Sapienza University of Rome.

The seventeenth century built the machinery of modern science - societies, journals, instruments - and a reputation could now be made by a result rather than by a patron.

His research centred on malaria.

His name is attached above all to studies about cardiovascular diseases, an examination of the corpus callosum of the brain, and is remembered in the eponymous Lancisi's sign. Natural history was the discipline in which the modern sciences were incubated, built on observation before instruments existed to help.

Recognition followed: Fellow of the Royal Society (1706).

What that record amounts to is a body of natural history that later workers could build on without re-checking. That is the practical test of a scientific life, and it is a harder one than fame.

Giovanni Maria Lancisi died in 1720, aged 66. What survives is not the reputation but the result: the part of natural history that no longer has to be argued for.
