Antonio Valisnieri

Antonio Vallisneri (Trassilico,3 May 1661 – Padua,18 January 1730) was an Italian medical scientist, physician and naturalist.

Vallisneri was born in Trassilico, a small village in Garfagnana, and graduated in medicine in 1684, in Reggio Emilia, under the guidance of Marcello Malpighi.

He studied at Bologna, Venice, Padua and Parma and held the chairs of Practical Medicine first and Theoretical Medicine later at the University of Padua between 1700 and his death.

Influenced by famous thinkers such as Leibniz and Conti he belonged to the Galilean school of experimental scientists. He worked in biology, botany, veterinary medicine, hydrology and the newly born science geology.

Vallisneri died in Padua in 1730.

He is known for being one of the first researchers in medicine to have proposed abandoning the Aristotelian theories for an experimental approach based on the scientific principles suggested by Galileo Galilei. Vallisneri stated that scientific knowledge is best acquired through experience and reasoning. This principle was followed in his anatomical dissections and carefully drawn descriptions of insects. For this reason, his medical career was at the center of heated controversy, as many of his contemporaries could not abandon prevailing medieval theories, even in the face of glaring experimental evidence.

He also was keenly interested in the natural sciences, and over his lifetime collected numerous specimens of animals, minerals and other natural objects. Unfortunately his scientific method was limited when it came to interpreting fossil evidence on mountain tops; the only possibility he allowed for was a miraculous Biblical Flood (Flood geology) as the cause for their deposition.
