Abbé Gasparo Ferdinando Felice Fontana (15 April 1730[1] – 9 March 1805) was an Italian polymath who contributed to experimental studies in physiology, toxicology, and physics. As a physicist he discovered the water gas shift reaction in 1780. He investigated the human eye and has also been credited with discovering the nucleolus of a cell. His work on the venom of vipers was among the earliest experimental toxicological studies. He served as a court physicist for Peter Leopold, Duke of Tuscany and taught at the University of Pisa. He was involved in the establishment of the La Specola museum in Florence.
