Alessandro Volta
1775
Volta invents the electrophorus which is a simple electrostatic generator with an insulating layer of resin and a metal plate. This type of device was the first of its kind to not be based off of continuous friction and rotation
1777
He invented the electrical pistol
• It is a glass container in the form of a pistol that is sealed with a tap in which a spark forces a mixtures of hydrogen and oxygen
• Was an attempt at building a new weapon

He invented the eudiometer
• A device for measuring the amount of oxygen in the air
• Mixes the air with a known amount of hydrogen and ignites it

1779
Appointed to the University of Pavia where he continued his work in static electricity
1791
Professor Luigi Galvani published his findings on “animal electricity”
1782
Proved that there was no “animal electricity” but metallic electricity.
1794
Married Teresa Peregrini. They had 3 sons
1800
March 14- Luigi Chiaramonth is crowned Pope Pius VII






April 16- William Chamber, Author/publisher (Basis of Communications and Codings) Birthday
1795
1805
1815
1825
1835
February 18 1745
Alessandro Volta is born in Como, Italy (then known as Lombardy, Italy)
July 15 1750
Halifax, Nova Scotia is almost completely destroyed by fire
October 23, 1760
1780
Professor Luigi Galvani investigated the contractions of a dead frog leg and called it “animal electricity”
1782
Volta invented the condensing electroscope
• An extremely sensitive measuring device that detected the existence of negatively charged particles in water vapour and in the smoke of burning coal

1797
He produced current electricity
1800
Volta later proves that Galvani’s “animal electricity” was not just metallic electricity that caused the frogs leg to move but it also came from the electrochemical reaction of the wet cardboard or metal which the leg was placed on
1800
Humphry Davy had established that Volta’s cells were providing electricity through chemical reactions and he reasoned that the reverse was true. The use of electricity might produce chemical reactions
1796-1801
Volta developed his battery.
• The idea came from Luigi Galvani’s discovery of “animal electricity”
• The original model was 2 bowls of salt water were connected and were placed on metal or a cardboard surface
• His later model was stacked on itself with alternating disks of saltwater soaked cardboard disks and copper or zinc disk. These piles of disks created a useful battery
• His stacked model lead to the term battery
• Was the first useable battery that provided a continuous source of electricity
• before he invented his battery, electricity could not be used or seen except in little spurts through static electricity
• Volta’s battery lead physicists and chemists to analyze chemical substances more easily

1806
Humphry Davy discovered potassium when he modified Volta’s cell, making it bigger, and the splitting bonds of potash
1810
Volta was made Count Volta and Senator of the Kingdom of Lombary by Napoleon I
1812
Joe Brammer (Brammah) patented a telescoping hydraulic jack that was applied to provide slow lift for heavy loads
1819
Volta Retired to his estate in Camnago, Lombardy, Italy



Hans Christian Oerstead discovered that when a wire that electricity flows through was brought near a compass, the compass needle would swing which concludes that magnetism and electricity are linked
1820
The Frenchman Andre Ampere and the German physicst S.C. Schweigger made a device to measure current which Ampere named the Galvanometer after Luigi Galvani
March 5th 1827
Alessandro Volta dies as age 82
March 15th 1827
The University of Toronto is chartered
1832-1833
Karl Friedrich Gauss developed an early type of telegraph
1885
1881
The unit of measurement of electromotive force is called the volt in honour of him and was adopted internationally in 1881
In his honour, a museum in Como, the Voltian Temple, has been reformed and houses some of his original instruments that he used to conduct experiments
1st Jewish Prayer book is printed in the United States
