Italophilia priest and mathematician, born in 1598, is known for his work on indivisibles, a precursor of infinitesimal calculus, and for Cavalieri's principle in geometry, which partially anticipated integral calculus. Alessandro Volta, born in Como in 1745, invented the first true electrical battery, known as the voltaic pile. It provided a continuous source of electric current, which greatly benefitted Ampere, Ohm and other electrical experimenters in their development of basic electrical theory. A unit of electricity (volt) is named in his honor. Italians such as Fallopio, Eustachi, Malpighi, Morgagni and Valsalva were important pioneers of modern anatomy at the University of
University of Pavia that immediately preceded the Unification (1859–66). During the following centuries, through periods of both adversity and prosperity, the fame of the University of Pavia grew over the last years due to the large number of applicants. Throughout its history, the university has benefited from the presence of many learned men and distinguished scientists who wrote celebrated works and made important discoveries: mathematician Girolamo Cardano (born in Pavia, 1501–76), physicist Alessandro Volta (Pavia chair of natural philosophy 1769-1804), poet Ugo Foscolo (chair of Italian eloquence 1809-10). Three Nobel Prize winners also taught in Pavia: physician Camillo Golgi (at Pavia from 1861),
