On June 12, 1898, William Ramsay and Morris Travers were systematically liquefying air and distilling it into fractions at University College London, searching for new elements among the noble gases. They had already found krypton ('hidden') and were running out of air to distill. That evening they isolated a tiny quantity of a gas that, when electrified in a vacuum tube, produced a brilliant crimson-orange glow unlike anything they had seen. Ramsay's thirteen-year-old son suggested the name novum, Latin for 'new.' Ramsay chose the Greek equivalent: neon (νέον), meaning 'new thing.'

Neon is extraordinarily rare in earth's atmosphere — about 18 parts per million, less than argon, less than helium. But its rarity is invisible. What made neon famous was its light. In 1902, the French engineer Georges Claude developed a method for liquefying air industrially. By 1910, Claude had sealed neon in glass tubes and electrified it, producing the first neon lamp. He displayed it at the Paris Motor Show in December 1910. The city of light had a new kind of light.

Claude brought neon signs to America in 1923, selling two to a Packard car dealership in Los Angeles. The signs cost $1,250 — roughly $22,000 in today's money. Passersby reportedly stopped their cars to stare. Within a decade, neon signs defined the American commercial landscape — Times Square, the Las Vegas Strip, Route 66 diners. Neon became the visual language of nightlife, commerce, and the twentieth-century city.

By the 1960s, cheaper fluorescent and LED alternatives began replacing neon signs, and the crimson glow retreated to vintage aesthetics and nostalgia. Today 'neon' is used loosely to describe any bright color, even when no noble gas is involved. The word has drifted from its element. But in a few cities — Tokyo, Hong Kong, old Las Vegas — real neon still burns, and the new gas that Ramsay found in the last dregs of liquefied air still lights up the night in its unmistakable red.
