Manganese: historical information

Manganese was discovered by Johann Gahn at 1774 in Sweden. Origin of name: from the Latin word "magnes" meaning "magnet", or "magnesia nigri" meaning "black magnesia" (MnO2).

Manganese metal was isolated by Gahn in 1774. He reduced the dioxide (MnO2, as the mineral pyrolusite) with charcoal (essentially carbon) by heating and the result was a sample of the metal manganese.
