Alessandro Volta

Early Life

  • Alessandro Volta was born the 18th of February 1745 in

  • Como, Italy.

  • When he was in his teens, he decided to be a scientist. So in 1774,

  • at the age of 30, he became a physics professor at the Royal School in

  • Como. Then one year later, he was appointed professor of physics at

  • the University of Pavia.

  • In the years between 1776-78 he studied the chemistry of gases

  • and descovered methane by reading a paper written by Benjamin

  • Franklin on “flammable air”. In November, of 1776, he found methane

  • at Lake Maggiore and then finally, in 1778, he managed to isolate

  • methane.

Volta and Galvani

  • In 1780 a friend of Volta’s, a scientist as him called Luigi

  • Galvani, told him about an experiment that he had tried.

  • Galvani explained that he was cutting up frogs and was holding their

  • muscles up on a brass hook. One muscle had come in contact with

  • some iron wire and it had twitched. Galvani thought that the muscle

  • was producing its own electricity but Volta didn’t quite agree. In fact,

  • he showed him that the contact was with the two different metals and

  • not with the muscle and the wire. This contact with the hook and the

  • wire made the muscle twitch.

Volta’s Experiment

  • Volta did many experiments to find out about the electricity that could

  • be produced. One of these experiments consisted in taking two piles

  • of coins, each pile made of a different metal, and separated them

  • with card soaked in a salt solution. This produced an electric current

  • and was, in fact, the world’s first battery.

  • Volta became very famous. Even Napoleon rewarded him by giving

  • him the title of Count.

  • Then at last, in 1827, he died at the age of 82 there in Como.

  • Volta’s legacy is celebrated by a Temple located in the public gardens

  • by the lake. It is also a museum which has been built in his honour

  • and some of his original equipment is shown.

  • The volt was then named after him in 1881.

  • Furthermore, he was depicted upon the italian 10,000 Lire.

Of course, if Alessandro Volta didn’t invent the battery, the electric

  • Of course, if Alessandro Volta didn’t invent the battery, the electric

  • objects we have now could have not been used because without a

  • battery these objects can’t work. So we are so lucky that Alessandro

  • Volta was brought to light.

  • The museums have immediately major renovations on the

  • becentenial of the invention of the battery. To these were added

  • several temporary exhibitions that have toured Italy, Europe and the

  • world.
