1894 by Lord Rayleigh (Britain, London) and William Ramsay (Britain, Bristol) husband found.

Source

In the air to account for 1%, from air to remove nitrogen, oxygen, carbon dioxide and water, can get the argon.

Element USES

Used for lighting, as inert gas, used to prevent the oxidation of the items.
