The Franklin stove is a metal-lined fireplace named after Benjamin Franklin, who invented it in 1741. It had a hollow baffle near the rear (to transfer more heat from the fire to a room's air) and relied on an inverted siphon to draw the fire's hot fumes around the baffle.
Swiss chemist, Aime Argand, invented a circular burner with a circular wick and used glass chimney to protect the flame from extinguishing. Gradually, the lamp fuel also evolved. As you may know, early lamps used animal fats, olive oil, beeswax or whale oil. The newer lamps ultimately used kerosene. However, kerosene, or coal oil, gave off an unpleasant odor and smoke. By the 1800's, paraffin oil, which is inexpensive and smokeless became the lamp oil of choice. With the invention of electricity in late 1800 by Benjamin Franklin and Thomas Edison, use of these lamps got scaled back.
