Facts about the Discovery and History of the Argon Element Argon was discovered by Sir William Ramsey in 1894. Sir William Ramsay (1852 - 1916) Sir William Ramsay discovered the noble gases and received the Nobel Prize in Chemistry in 1904 "in recognition of his services in the discovery of the inert gaseous elements in air". These elements included neon, krypton and Xenon. Ramsay also isolated Helium which had been observed in the spectrum of the sun but had not been found on earth. In 1910 Ramsay also made and characterized radon.
