Celebrated Swedish scientist and a respected and renowned professor at the University of Uppsala. He developed several branches of science and made important contributions in the field of inorganic chemistry. He made noteworthy contributions to mineralogy and should be considered a PIONEER in the classification of minerals according to their chemical composition. He also carried out studies on chemical affinity, and his tables were doubtless the most complete of the time. He was professor to Juan José Elhuyar, who attended Bergman's ‘advanced chemistry’ course in the city of Uppsala, achieving great academic performance.
