When was the first neon sign made?

Neon sign - is the first neon sign was made by Georges Claude in France in 1910. Neon, an inert gas, was discovered in 1898 by the British scientists Sir William Ramsay and M. W. Travers. It is colourless, odourless and tasteless and is widely distri­buted in nature. Neon is called an inert gas because it is not affected by the usual chemical reactions.

 In 1850 a German physicist, Heinrich Gessler, demonstrated that a brilliant light is produced when electricity is discharged through such a gas. Neon proved to be ideal for advertising because of its unusually high electrical conductivity, its adaptibility, its high luminosity and the brilliant colours obtainable by the addition of other inert gases and mercury vapour.

 But neon light tubes do not give enough light for general illumina­tion, and the colours that can be produced from it are not suitable for indoor lighting.
