Neon (Greek neos meaning "new") was discovered (1898) by the British chemists Sir William Ramsay and Morris W. Travers. The reddish-orange color that neon emits in neon lights is widely used to make advertising signs. "Neon" is also used generically for these types of lights when in reality many other gases are used to produce different colors of light. Other uses: high-voltage indicators, lightning arrestors, wave meter tubes, television tubes. Neon and helium are used to make gas lasers.
