Leclanché was born in Parmain, France in 1839, the son of Léopold Leclanché and Eugenie of Villeneuve. He was educated in England and completed his education in the École Centrale des Arts et Manufactures engineering school, graduating in 1860 to begin work as an engineer.
[edit] Leclanché cell
In 1866 he invented the Leclanché cell, one of the first electrical batteries and the forerunner of the modern dry cell battery. It comprised a conducting solution (electrolyte) of ammonium chloride with a negative terminal of zinc and a positive terminal of manganese dioxide.
Leclanche's "wet cell" (as it was popularly called) was the forerunner to the world's first widely used battery, the Zinc-carbon battery.
