Dolcè, near Verona
|Died||29 March 1873
A native of Dolcè, near Verona, Zantedeschi was for some time professor of physics and philosophy in the Liceo of Venice. Later he accepted the chair of physics in the University of Padua, which he held until 1853 being then obliged to resign on account of failing sight. He was an ardent worker and prolific writer, 325 memoirs and communications appearing under his name in the Biblioteca Italiana and the Bibliotheque Universelle de Geneve.
Zantedeschi died at Padua in 1873.
In 1829 and again in 1830, Zantedeschi published papers on the production of electric currents in closed circuits by the approach and withdrawal of a magnet, thereby anticipating Michael Faraday's classical experiments of 1831.
He also thought that he had detected, in 1838, a magnetic action on steel needles by ultraviolet light. Though this effect was not confirmed, it is interesting to note that a connection between light and magnetism was suspected so many years before the announcement in 1867 by James Clerk Maxwell of the electromagnetic theory of light.
In a tract of 16 pages, published in 1859, Zantedeschi defended the claims of Gian Domenico Romagnosi to the discovery in 1802 of the magnetic effect of the electric current, a discovery which is usually accredited to Hans Christian Ørsted in 1820. Zantedeschi's experiments and papers on the repulsion of flames by a strong magnetic field (discovered by Padre Bancalari of the Pious Schools in 1847) attracted general attention at the time.
In his later years Zantedeschi dictated an autobiography which is kept in the archives of the Academy of Verona. His principal works are: Ricerche sul termo-elettricismo dinamico (1838) and Trattato del Magnetismo e della Elettricita (1843).
