Ami Argand (5 July, 1750–14 October, 1803) was a Swiss physicist and a chemist who invented the Argand Lamp, which was a huge success on the usual oil lamp. Fascinated by the aptitude of science, he became an apprentice of Benedict de Saussure, a renowned meteorologist and a botanist. He began his invention in the 1780’s when he was a teacher in Chemistry. His idea was to develop a lamp which could overcome the drawbacks of the traditional ones. A series of experiments led to the prominent discovery of what we now know as the Argand Lamp.
Later in 1783, he was thrilled by the idea of hot air balloons which was originally a thought of Etienne Montgolfier. The invention of the lamp was not so easy. After a huge series of experiments, and partnerships of many other significant people, he was finally able to manufacture his lamp. It was in 1784 that he received a patent for his discovery. The design and the usability of the lamp was so good that people were highly demanding for this product.
