  Ignatius Gottfried Kaim was an Austrian chemist. In his dissertation De metallis dubiis published in 1770 Kaim describes the reduction of manganese oxide with carbon and the formation of a brittle metal. This is the first description of manganese metal several years before the better known synthesis of Johan Gottlieb Gahn in 1774.
