Google has celebrated the 270th birthday of the Italian physicist Alessandro Volta with a doodle on its homepage.

Volta, who was born Alessandro Giuseppe Antonio Anastasio Volta, is best known for inventing the first battery.

Born in Como, Italy, he gave his name to the electrical unit 'volt' in 1881.
In 1774, Volta became the professor of physics at the Royal School of Como. A year later, he invented the electrophorus: a device used to generate static electricity.

During his tenure at the university, he also discovered and isolated methane gas.
By 1779, Volta was appointed to the chair of physics at the University of Pavia.
 
The turning point for Volta’s development of the battery was in 1780, when his friend Luigi Galvani 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.

Just six years later, Volta invented the first electric battery, which he would go on to showcase at year later in front of Napoleon in Paris. The leader was so impressed that he made Volta a count and senator of the kingdom of Lombardy.
Later, the emperor of Austria made him director of the philosophical faculty at the University of Padua in 1815.

Volta died on 5 March, 1827 in Como.
