François Pierre Ami Argand (5 July 1750 – 14 October 1803)

------- During this period, in 1780, he started to invent improvements on the conventional oil lamp. The basic idea was to have a cylindrical wick which air could flow through and around, increasing the intensity of the light produced. A cylindrical chimney enhanced the air flow and a series of experiments gave the proportions for optimum operation.^[2] A mechanism for raising and lowering the wick allowed some adjustment and optimization as well. The light was much brighter than a candle (by a factor of five to ten), burned cleanly, and was cheaper than using candles. ----------
