Volta, Conte Alessandro

▪ Italian scientist
in full  Alessandro Giuseppe Antonio Anastasio Volta 
born February 18, 1745, Como, Lombardy [Italy]
died March 5, 1827, Como
 Italian physicist whose invention of the electric battery provided the first source of continuous current.

      In 1775 Volta's interest in electricity led him to invent the electrophorus, a device used to generate static electricity. He became professor of physics at the Royal School of Como in 1774 and discovered and isolated methane gas in 1778. One year later he was appointed to the chair of physics at the University of Pavia.

      In 1780 Volta's friend Luigi Galvani (Galvani, Luigi) discovered that contact of two different metals with the muscle of a frog resulted in the generation of an electric current. Volta began experimenting in 1794 with metals alone and found that animal tissue was not needed to produce a current. This finding provoked much controversy between the animal-electricity adherents and the metallic-electricity advocates, but, with his demonstration of the first electric battery in 1800, victory was assured for Volta. In 1801 in Paris, he gave a demonstration of his battery's generation of electric current before Napoleon, who made Volta (volt) a count and senator of the kingdom of Lombardy. The emperor of Austria made him director of the philosophical faculty at the University of Padua in 1815. The volt, a unit of the electromotive force that drives current, was named in his honour in 1881.
