The firm Liotard was one of the french manufacturers of lighting.
One of the earliest publications goes back to the year 1906.
In this publication we find kerosene "NOËL" burners for upright "gas" mantles for a central lighting system

In an anouncement for clients in 1922 we read:
To our dear clients
The Liotard-Corporation is pleased to inform its clients that they took over from Mr. Ch. Liotard the well-known company, founded in 1858 and managed through the years by Liotard Jr., Liotard widow, Liotard. Bros. and finally Charles Liotard.
This company will go on manufacturing in the most perfect way the specialties of its predecessors for its numerous clients, keeping safe the house's reputation as a good brand.
Not more than previously, our company doesn't have any other premises in Paris than 22 rue de Lorraine.
Please don't become confused with companies that have similair names.
The trademark LILOR adopted by the company will guarantee for a good quality.

On the left an example of a gasoline pressure installation with three recervoirs. From the recervoirs a hollow wire (tombak) feeds lamps, heaters, stoves and even boilers.
Due to this wire such a system is often referred to as a "hollow wire" system.

Here we have the 120 "Bougies" "MAGIC" hollow wire burner.
The burner takes a steel ring mantle wich has a bajonet fixture.
Lighting is done by pre-heating section I which would work quickly.

Here we have the "ATOUT" hollow wire burner.
The burner is shown here with a hard mantle which has a bayonet ceramic fixture. (showed below)
Lighting is done by pre-heating the center section with a burning alcohol torch.

Here we have the "AINE" (hollow wire) burner.
The burner is shown here with a "three prong" burner head for mounting a soft mantle with has a metal ring. (showed below)

This is the 150 "Bougies" "LOR" hollow wire burner.
This burner has one knob for openening and closing the valve and one knob for cleaning the jet.
Lighting is done by pre-heating section I with a burning alcohol torch.

This is one nice design of Liotard with the LOR burner.
This lamp can be used as a table lamp or as a wall lamp.
Notice the fact that this is not a hollow wire system.

This is the 150 "Bougies" "STA" hollow wire burner.
This burner has only one knob for openening and closing and cleaning the jet.
Lighting is done by pre-heating section I with a burning alcohol torch.

But Liotard didn't make all appliances themselves they also operated
as a wholesaler for other brands for instance Coleman and Ditmar.
