An Argand lamp is a lamp with a circular hollow wick and glass chimney which allows a current of air both inside and outside the flame.

Swiss chemist Aime Argand invented the oil lamp in the 18th century to provide a more efficient and brighter source of lighting compared to candles. His design featured a cylindrical wick and a glass chimney, which allowed for better airflow and reduced smoke, resulting in a more reliable and longer-lasting light source.

An Argand Diagram is a graphical representation of a complex number. The real part is the horizontal coordinate, and the imaginary part is the vertical coordinate. See Related Link at Wolfram MathWorld.
In the 18th century, the central burner was invented, a major improvement in lamp design. The fuel source was now tightly enclosed in metal, and a adjustable metal tube was used to control the intensity of the fuel burning and intensity of the light. Around the same time, small glass chimneys were added to lamps to both protect the flame and control the flow of air to the flame. Ami Argand, a Swiss chemist is credited with first developing the principal of using an oil lamp with a hollow circular wick surrounded by a glass chimney in 1783.
