Invention
Georges Claude, a French chemist, is credited as the originator of the neon sign. The invention publicly debuted on December 11, 1910.
Process
The illuminated signs are constructed with glass tubes bent to desired shape. Only the tubes that produce red hues contain neon. Secondary colors such as gold and green are created through the use of argon or mercury.
Importation
The earliest neon signs within the United States date to the 1920s. The first sign advertised a Los Angeles Packard automobile dealership in 1922.
Popularity
Demand for signs crested in the 1950s and 1960s. Flashing neon was perceived to distract drivers and cause accidents. The signs were replaced with low maintenance and economical backlit signs.
Collecting
As the popularity of neon signs faded, a collector's market was created.
Modern Signs
Modern neon signs most commonly consist of cathode tubes shaped into adjoining letters, or channel letters.
