The Italian physicist Alessandro Volta is known for his pioneering work in electricity. Volta was born and educated in. In 1774 he became professor of physics at the Royal School in Como and in 1779 he became professor of physics at the University of Pavia, a chair he occupied for 25 years. By 1800 he had developed the so-called voltaic pile, a means of converting chemical energy into electrical energy formed the basis for nearly all modern batteries, which produced a steady stream of electricity. In honor of his work in the field of electricity, Napoleon made him a count in 1801.
Beginning his work in 1793, Volta observed the electrical interaction between two different metals submerged near each other in an acidic solution. Based on this principle, in 1779 he presented his first battery consisted of a series of alternating copper and zinc rings in an acid solution known as an electrolyte. He called his invention a column battery, although it came to be commonly known as the Volta battery or Voltaic cell. The term volt, a unit for measuring electrical potential difference and electromotive force, is also derived from his name.
One curious note: the alkaline storage battery, in common use today, was developed in 1914 by Thomas Alva Edison. It is so called because the electrolyte is alkaline, or basic, rather than acidic.
