This Welsbach lamp is named after Dr. Carl Auer von Welsbach (1858-1929), an inventor born in Vienna, Austria. He is best remembered for inventing the electric metal filament light bulb, still used today. He also specialised in the design of gas lamps.
A Welsbach burner was a light operated by the combustion of a mixture of air and gas, which was used to heat a gas mantle to incandescence. A mantle of ash was protected by a shade. Later on gas lanterns were worked by pressurised gasoline being vaporised while passing through a fine jet.
