Who invented the lamp?
The first artificial lamp came from fire. Then some 20, 000 years ago, people realized that they could get light by burning oil. Lamps with vegetable fibres as wicks, were first made in 1000BC. Candles appeared about 2000 years ago. In 1859, drilling for petroleum oil began, and the kerosene lamp was first introduced in 1853 in Germany. Coal gas was first used as lighting fuel as early as 1784. A German inventor Freidrich Winzer was the first person to patent coal gas lighting in 1804.
