Count Alessandro Volta Biography (1745 - 1827) (1745 - 1827) Born in Como, Italy, into a noble family, Count Volta was a physicist and pioneer in the study of electricity. "Volt," named after Count Volta, is a measurement of electricity. Count Volta also made discoveries in electrostatics, meteorology and pneumatics. Inventions and Discoveries His most famous invention, however, is the first battery. The idea came from Luigi Galvani, an anatomist. Galvani was dissecting a frog when the frog's leg began to twitch Galvani thought was because of some type of

electrical action in the vicinity, such as lightening Volta tried to duplicate the experiment, and he did on a clear day when there was no lightening. Through experimentation, Volta realized that the two different metal objects holding the frog leg might be the source of the action. Over a period of several years he worked out that the wet muscle tissue conducted a current between the two different types of metals. Around 1800, he invented a wet battery called a Voltaic Pile. The Voltaic Pile consisted of discs of copper and zinc separated by discs of paper or cardboard (soaked in salt water). In 1775, Volta improved and popularized the electrophorus , a device that produces a static electric charge. His promotion of it was so extensive that he is often credited with its invention, even though a machine operating in the same principle was described in 1762 by Swedish professor Johan Carl Wilcke. Honors In honor of his work in the field of electricity , Napoleon Bonaparte made him a count in 1810; in 1815 the Emperor of Austria named him a professor of philosophy at Padua. Before 1796, Lombardy was ruled by Austria. From 1796 to 1815, Lombardy came under Napoleon's rule. After 1815, Lombardy was once again under Austrian rule. Thus Volta was once a subject of the Emperor of Austria, later a subject of Napoleon and then later a subject of the Emperor of Austria again. Volta is buried in the city of Como . At the Templo Voltiano near Lake Como there is a museum devoted to explaining his work.
