The details of the discovery are well recorded thanks to numerous
published works, including several books authored by Travers later in his life. "The blaze of crimson light from the tube
told its own story, and it was a sight to dwell upon and never to forget," he remembered
in The Discovery of the Rare Gases, published in 1928: "nothing in the world gave a glow such as we
had seen."
Sir William Ramsay's discovery of neon and the other noble gases helped earn him the Nobel Prize for Chemistry in 1904. It was Ramsay's adolescent son Willie whose suggestion led the gas to be called "neon" in 1898. (NobelPrize.org)
At risk of some reckless oversimplification, I will attempt to reduce the science to layman's terms. Ramsay and Travers spent years isolating the various gases that exist in the earth's atmosphere – in other words, breaking the air we breathe down into its component parts. To do this, they cooled air to an extremely low temperature, turning it to liquid. As the liquid air then warmed, its component elements returned to a gaseous state in sequence, making it possible to collect small samples of them individually. In addition to neon, this basic principle enabled Ramsay to discover argon, krypton and xenon. Neon's luminous properties became apparent almost immediately: as a matter of course, Ramsay and Travers passed an electric current through a glass-enclosed sample of the gas, an analysis of the resultant glow helping to determine whether they indeed had found a new gas.
All of this happened in the last years of the long reign of
Queen Victoria: odd as it may seem, neon is a bona fide product of the Victorian
era. By at least one account, Ramsay and
Travers used neon together with several other gases to make an illuminated sign
in tribute to Victoria in 1898. (My efforts to find primary documentation of
this sign have thus far come to naught.)
Another decade would pass before other developments facilitated the commercial viability of neon illumination. For all the controversy that would haunt the evolution of neon signs in the years that followed, credit for neon's place on the periodic table remains securely with Ramsay and Travers.
Hooray!
