He was the chemist for The Swedish Board of Mines Bergskollegium from 1773 – 1817. Gahn was however very reluctant to publish his scientific findings himself, but freely communicated them to Bergman and Scheele. One of Gahn's discoveries was that manganese dioxide could be reduced to manganese metal using carbon, becoming the first to isolate this element in its metal form.
