What kind of business purchased the first commercial lit sign? Where?

Need help?
"1910 international Expo".

I know that the French auto company Citroen had a sign on the Eiffel Tower for a while, but I don't know what year it was. However, I am fairly sure that electrically-lit commercial signs existed before 1910.

I wasn't thinking about a 2 bulbs sign, but a real commercial neon sign.

Neon makes a difference. There were quite a few elecrrically-lit signs before neon signs, at least one was similar to neon in that it used a gas, carbon dioxide.

According to my source we are talking about the same guy. He started with Carbon dioxide and nitrogene.

The Citroen sign was hardly a two bulb sign.
The Art Deco work spanned the length of the Eiffel Tower. Designed for the Exhibition of Decorative Arts, the sign had 200,000 electric lights and needed its own power plant. Its message, touting the Citroen automobile, could be seen 24 miles away.

Your site mentions 74 years ago, which means 1931.The sign I'am talking about is older than that...... how about 1912.But you,ve found the right place...Paris.

Below is from Inventors.About.com. Generally a good site, it nevertheless has some errors in it. (One I noticed tonight was about the length of a Slinky. About says 80', Mr. Slinky's son told me 61-62' when I called the company a while back.) See AnswerPool Trivia Here for Mr. Slinky's son

The concept behind neon signs was first conceived in 1675, when the French astronomer Jean Picard observed a faint glow in a mercury barometer tube. When the tube was shaken a glow called barometric light occurred, but the cause of the light (static electricity) was not then understood.

The French engineer, chemist, and inventor Georges Claude (b. Sept. 24, 1870, d. May 23, 1960), was the first to apply an electrical discharge to a sealed tube of neon gas (circa 1902) to create a lamp. The word neon comes from the Greek "neos," meaning "the new gas." Georges Claude displayed the first neon lamp to the public on December 11, 1910, in Paris. In 1923, Georges Claude and his French company Claude Neon, introduced neon gas signs to the United States, by selling two to a Packard car dealership in Los Angeles. Earle C. Anthony purchased the two signs reading "Packard" for $24,000. Neon lighting quickly became a popular fixture in outdoor advertising. Visible even in daylight, people would stop and stare at the first neon signs dubbed "liquid fire."

History Note: Before there were neon signs in America, there were commercial sign tubes that used a carbon dioxide fill. The carbon dioxide signs were made by a man called Moore. Neon gas was discovered by William Ramsey and M. W. Travers in 1898 in London.

The first link in my post above was to a site about 1999, so it was referring to 1925, when the Citroen light was on the tower. I am not questioning the 1910 date for the first neon ommercial sign, just the first electrically-lit commercial sign.

I,ve got to give it to you DG, you kinda have the answer I was looking for, about Georges Claude.

The First Sign


Jaques Fonseque, Claude’s associate, sold the first commercial sign in 1912 to a Paris barber.

I guess "Paris ville-lumiere" came from there.!
