Manganese processing Britannica

Metallic manganese was first isolated in 1774 by Johan Gottlieb Gahn, a Swedish mineralogist who reduced pyrolusite, a manganese dioxide ore, with carbon. In 1856 Robert Forester Mushet, a British steelmaker, used manganese to improve the ability of steel produced by the Bessemer process to withstand rolling and forging at elevated temperatures.
