Early Life and Works
Volta was born in Como, a town in present day northern Italy (near the Swiss border) on February 18, 1745. In 1774, he became a professor of physics at the Royal School in Como. A year later, he improved and popularized the electrophorus, a device that produced static electricity. 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 the Swedish experimenter Johan Wilcke.
In the years between 1776–78, Volta studied the chemistry of gases. He discovered methane after reading a paper by Benjamin Franklin of America on "flammable air", and Volta searched for it carefully in Italy. In November, 1776, he found methane at Lake Maggiore, and by 1778 he managed to isolate methane. He devised experiments such as the ignition of methane by an electric spark in a closed vessel. Volta also studied what we now call electrical capacitance, developing separate means to study both electrical potential (V ) and charge (Q ), and discovering that for a given object, they are proportional. This may be called Volta's Law of capacitance, and it is likely that for this work the unit of electrical potential has been named the volt.
In 1779 he became a professor of experimental physics at the University of Pavia, a chair that he occupied for almost 25 years. In 1794, Volta married an aristocratic lady also from Como, Teresa Peregrini, with whom he raised three sons: Giovanni, Flaminio and Zanino.

Famous quotes containing the words early, life and/or works:
“The science, the art, the jurisprudence, the chief political and social theories, of the modern world have grown out of Greece and Rome—not by favor of, but in the teeth of, the fundamental teachings of early Christianity, to which science, art, and any serious occupation with the things of this world were alike despicable.”
—Thomas Henry Huxley (1825–95)
“His life itself passes deeper in nature than the studies of the naturalist penetrate; himself a subject for the naturalist. The latter raises the moss and bark gently with his knife in search of insects; the former lays open logs to their core with his axe, and moss and bark fly far and wide. He gets his living by barking trees. Such a man has some right to fish, and I love to see nature carried out in him.”
—Henry David Thoreau (1817–1862)
“We do not fear censorship for we have no wish to offend with improprieties or obscenities, but we do demand, as a right, the liberty to show the dark side of wrong, that we may illuminate the bright side of virtue—the same liberty that is conceded to the art of the written word, that art to which we owe the Bible and the works of Shakespeare.”
—D.W. (David Wark)
