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. n 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. While carrying out researches on the solar spectrum, Zantedeschi was among the first to recognize themarked absorption by the atmosphere of red, yellow, and green light
