Johan Gottlieb Gahn (19 August 1745 – 8 December 1818) was a Swedish chemist and metallurgist who isolated manganese in 1774. Gahn studied in Uppsala 1762 – 1770 and became acquainted with chemists Torbern Bergman and Carl Wilhelm Scheele.
Johan Gottlieb Gahn (born Aug. 19, 1745, Voxna, near Söderhamn, Swed.—died Dec. 8, 1818, Stockholm) was a Swedish mineralogist and crystallographer who discovered manganese in 1774.

Johan Gottlieb Gahn. 1745-1818. Swedish chemist and mineralogist who first isolated the pure metal manganese (1774). Gahn interacted closely with Karl Scheele, and conversations they had regarding Scheele's research led to Gahn's demonstration that bones contain phosphorus (1770).
Johann Gottlieb Gahn. 1745-1818. Swedish chemist and mineralogist who, with Karl Scheele, discovered that phosphorus is essential to the structure of bone. In fact, bones and teeth are formed of a calcium phosphate mineral, apatite, secreted by bone-forming cells.
