People of the Industrial Revolution

Pierre-Émile Martin (French: [pjɛʁ emil maʁtɛ̃]; 18 August 1824, Bourges, Cher – 23 May 1915, Fourchambault) was a French industrial engineer. He applied the principle of recovery of the hot gas in an open hearth furnace, a process invented by Carl Wilhelm Siemens.
In 1865, based on the Siemens process, he implemented the process which bears his name for producing steel in a hearth by remelting scrap steel with the addition of cast iron for the dilution of impurities.
His work earned him the award of the Bessemer Gold Medal of the Iron and Steel Institute in 1915 and of the French nation (knight in 1878 then Officer of the Legion of Honour in 1910).

Georges Leclanché (9 October 1839 – 14 September 1882) was a French electrical engineer chiefly remembered for his invention of the Leclanché cell, one of the first modern electrical batteries and the forerunner of the modern dry cell battery.
