Aimé Argand (1755-1803),or Francois Pierre Ami Argand,Swiss physicist and chemist who revolutionised conventional oil lamps by producing the first scientifically designed oil burning lamp,patented in England in 1784. The Argand lamp consisted of a cylindrical wick positioned between two concentric metal tubes so that air was supplied to both inside and outside of the circular flame. The addition of a circular glass chimney created a greater draught and a steadier flame.It was manufactured by Matthew Boulton and was five to ten times brighter than a candle. Argand type lamps eventually became the standard source of illumination in homes,shops and public buildings throughout Europe and was much used in lighthouses | |
