Neon was discovered in 1898 by the British chemists Sir William Ramsay and Morris W. Travers in London.
It was discovered when Ramsay chilled a sample of air until it became a liquid, then warmed the liquid and captured the gases as they boiled off.
After 1902, Georges Claude's company, Air Liquide, was producing industrial quantities of neon as a byproduct of his air liquefaction business.
